CHAPTER-1

INTRODUCTION TO TECHNOLOGY USED

Although the other programming languages which existed before the origin of Java were as good and

user friendly to the professional programmers, they still expected something advance to come up with all

those features which were definitely the cause of worry to them with respect to the security of their code

and this thought gave birth to a revolution which discovered another Programming Language-JAVA with

the features to ensure the security and the portability of their programs. Developing your applications

using the Java programming language results in software that is portable across multiple machine

architectures, operating systems, and graphical user interfaces, secure, and high performance.

Java was originally developed at Sun Microsystems in 1991 to provide a platform-independent

programming language and operating system for consumer electronics (TV sets, toasters and VCRs). In

syntax and execution, Java is a lot like a simplified version of C++.. It is a highly robust, distributed, high

performance, object-oriented, multi-threaded language with all of the usual features. As such, it builds

upon years of C++ development, taking the good and dispensing with the bad. As it so happened

however, Java did not make it into the consumer electronics market. Instead it wound up in our web

browsers. Java seemed to be a perfect fit for the web. The language itself was extremely small. Thus itcould quickly be transferred over the web.

Further, Java was platform independent. That is, any computer with a Java virtual machine can run a Java

program. Programs can be written anywhere and be run anywhere. This is crucial because if a language

can not run on any machine, it cannot be used on the web that must service every machine, language, and

environment imaginable. Platform independence works because Java is an interpreted rather than a

compiled language. Unlike C or C++ code, when Java is compiled, it is not compiled into platform

specific machine code, but into platform independent byte code. This byte code is distributed over the

web and interpreted by a virtual machine on whichever platform it is being run. Perhaps a picture would

be useful...

Thus, as a programmer, you need only concern yourself with the generic Java programming language and

compile your applications into byte code on whatever system you are using. You can then be assured that

your byte code will be executed correctly whether your clients are using Macs, Pcs, Unix boxes or

anything else. Perhaps the best summary of the design goals and accomplishments of Java comes from

Gary Cornell in the introduction to Core Java. In this introduction, Cornell outlines 12 design principles

used in the development of the Java language. To do so, he quotes from the Java White Paper from Java

soft. I will duplicate the quotes here, but you should not consider your Java Library complete without a

copy of Core Java. Java is Simple."We wanted to build a system that could be programmed easily without

a lot of esoteric training and which leveraged today's standard practices...

So even though we found that C++ was unsuitable, we designed Java as closely to C++ as possible in

order to make the system more comprehensible. Java omits many rarely used, poorly understood,

confusing features of C++ that, in our experience, bring more grief than benefit."

Not only the security, but there were few more areas which were taken care by this Programming

Language normally identified as the JAVA-BUZZWORDS. These words define the additional features

and considerations which gave JAVA- complete success and acceptance from the programmers of the

software World. Together, the above requirements comprise quite a collection of buzzwords .

1.1 Features of the Java Language

Having seen that Java is equally suited as a language for development both on and off the Internet, it's

time to look more closely at the Java language itself. The creators of Java at Sun Microsystems have

defined the Java language as "a simple, object-oriented, distributed, interpreted, robust, secure,

architecture-neutral, portable, high-performance, multithreaded, and dynamic language." Well, they

managed to fit all of the important 1990s buzzwords into one sentence, but we need to look more closelyat Java to see if they managed to fit all of these concepts into one language.

* Simple & Object-oriented

* Secure & Portable

* Robust

* Multithreaded & Architecture-neutral

* Interpreted

* Distributed & Dynamic

* High performance

Fig1. features of java

1.1.1.Simple and Object-Oriented

As mentioned above while discussing the overview of Java we understood that Java got its origin as a

result of the deep study of the pre-existing Programming languages like C and C++. It makes very easy

for any professional programmer to have a clear understanding of Java and its functionality if he has basic

knowledge of C++ and the OOPS (Object Oriented programming) concepts .And hence the fundamental

concepts of Java technology can be grasped quickly and the programmers can be productive from the

very beginning as its look and feel makes it comfortable to the programmers as the beginners of Java Too.

Not only this, the Founders of JAVA made sure that although Java is originated from the basics of the

pre-existing Programming Languages it still avoids the features of those languages which were confusing

and were not accepted happily by the Professionals. The Java programming language is designed to be

object oriented from the ground up. After thirty years of regular exercise finally the Object technology got

the acceptance in the programming mainstream. The Object Oriented Concepts made it possible to

function within increasingly complex, network-based environments, and so it can be concluded that Java

technology provides a clean and efficient object-based development platform to the programmers.

1.1.2.Secure & Portable

As discussed previously, under the head JVM (Java Virtual machine ) , the output which we get from the

Java Complier is not in the form of directly Executable Code b ut it is in the form of BYTE CODES.,

Byte code is nothing but the set of instructions which are executed by the Java Run time Environment, the

JVM. Irrespective of all the other programming languages which are complied, java is actually interpreted

by the JVM and hence makes it very much safe and secure to be downloaded through the internet as JVM

makes sure that the Java Program is in its complete control and do not effect anything outside its

environment.

Since the code gets converted into the Byte Code by the JVM, it gives huge amount of portability to Java

as it can run on any platform in any environment provided they have the JVM available on it. The Bytecodes will always be the same in spite of having variations in the JVM with respect to the environment

and this is one of the other very strong supportive features of JAVA.

1.1.3.Robust

Java is considered to be a very robust Programming language ass it ensures that the Java Programs run

easily and successfully on the variety of environments and platforms. Since Java is a strictly typed

language it helps the programmer to reduce the chances of making the run time errors and also handlingthem within the programs itself which normally cannot happen in other programming languages.

1.1.4.Multithreaded & Architecture-neutral

Multithreading is another feature of Java which lets programmer opt for Java as the programming

language as it facilitates the programmer to do various tasks within one program itself without having

issues of conflicts between the tasks. As its been discussed earlier in the sections above, that Java

Program gets converted into Byte Code which is very much platform independent it makes Java as highly

Architecture-neutral. And hence it can be stated that Java has successfully achieved write once; run

anywhere, any time, forever. which was the basic goal of the inventors of Java Programming Language.

1.1.5.Interpreted

Java programs get converted into Byte code which is easily interpreted by the JVM on any machine and

in any environment and although it gets interpreted by the JVM it is not the case that the Java Code cant


5/31


5

be complied into the native machine code and it is taken care by the JIT (JustIn-Time) Complier which

is available with the JVM and thus ensures very high Performance of the language.

1.1.6.Distributed and Dynamic

Since, Java was designed with the aim of making it accessible over the internet, providing it the feature of

being called as Distributed programming language was very important as it had to handle the TCP/IP

protocols of the internet .Java technology and its runtime environment have combined them to produce a

flexible and powerful programming system.

Since the byte codes are loaded in small application forms as applets it becomes

mandatory for Java programs to carry the sufficient amount of information related to the objects which

are executed at the run time so as to provide verification with respect to that particular object hence

giving it the feature of being called as Dynamic Language too. These above mentioned features can be

easily termed as the major wings of the Java Programming language which has given it the open

acceptance of the professions of the programming World.

1.1.7.High-Performance

For all but the simplest or most infrequently used applications, performance is always a consideration. It

is no surprise, then, to discover that achieving high performance was one of the initial design goals of the

Java developers. A Java application will not achieve the performance of a fully compiled language such

as C or C++. However, for most applications, including graphics-intensive ones such as are commonly

found on the World Wide Web, the performance of Java is more than adequate. For some applications,

there may be no discernible difference in performance between C++ and Java.

Many of the early adopters of C++ were concerned about the possibility of performance degradation as

they converted their programs from C to C++. However, many C++ early adopters discovered that,

although a C program will outperform a C++ program in many cases, the additional development time

and effort don't justify the minimal performance gains.

Of course, because we're not all programming in assembly language, there must be some amount of

performance we're willing to trade for faster development. It is very likely that early experiences with

Java will follow these same lines. Although a Java application may not be able to keep up with a C++

application, it will normally be fast enough, and Java may enable you to do things you couldn't do with

C++.

1.2 Java as a General-Purpose Language

Of course, the use of Java extends beyond the Web, and there is much to recommend Java as a general-

purpose development language. You've already seen that Java is completely portable to a variety of

hardware platforms and operating systems. In this section, you'll learn about some of Java's attributes that

make it a desirable general-purpose language.

For example, because Java borrows much of its syntax and many of its concepts from C and C++, there is

a preexisting pool of programmers who could quickly learn Java. However, Java goes far beyond being a

mere derivative of C++. It adds to C++ in the areas of automatic memory management and language-level

support for multithreaded applications. On the other hand, Java remains easier to learn and simpler to use

than C++ because of those C++ features that were left out of Java: multiple inheritance, pointers, and the

goto statement, among others.

Because implementations of the Java Virtual Machine can be very efficient, it is possible for Java

programs to run almost as quickly as C++ programs. This is a key feature in convincing developers that

Java is a viable language for non-Internet development. Because of Java's strengths as an Internet

language, many of these same strengths apply when Java is used as a language for client-server

development. It is very likely that as corporations do more and more Internet development in Java, they

will begin to apply these same Java developers to their client-server projects. Java's strengths in terms of

network awareness, security, portability, and performance make it ideally suited for corporate client-

server development, as well as Internet development.

1.3.Applications and Applets

In discussing Java programs, it has become standard to refer to Java programs that are embedded in

another language as applets and to stand-alone programs as applications. For example, when you use Java

to augment a World Wide Web page, the Java code is embedded within HTML code. Therefore, this is

referred to as an applet. On the other hand, a Java program that is not embedded within HTML or any

other language and can stand on its own is referred to as an application.

Of course, there is a subtle implication here that applications are larger (and, therefore, presumably more

complex) than applets. However, this is not necessarily true. Applications and applets alike can range

from simple one-class programs to programs with hundreds of classes. The implication that an applet is

somehow less than an application is unfortunately a connotation it is necessary to live with in an

otherwise valid distinction.


7/31

1.4.The Java Tools

Of course, in order to write Java applications or applets, you need more than a language-you need the

tools that let you write, test, and debug your programs. This section gives a very high-level overview of

the various Java tools that come with the Java Developer's Kit.

1.4.1.Compiler

There is, of course, a Java compiler, named javac. The Java compiler takes input source code files (these

files typically have the extension .java) and converts them into compiled byte code files. javac: The Java

Compiler."

1.4.2.Interpreter

The Java interpreter, known eponymously as java, can be used to execute Java applications. The

interpreter translates byte codes directly into program actions.

1.4.3.Debugger

The Java debugger, jdb, enables you to debug your Java classes. Unfortunately, the Java debugger is a

throwback to the pre-GUI debugger dark ages of programming. The Java debugger is a command-linedebugger that is enough to make you wish for even the 1988 version of CodeView. However, we can use

the jdb to set breakpoints, inspect objects and variables, and monitor threads.

1.4.5.Disassembler

One of the basic tenets of object-oriented programming is that programmers unfamiliar with a class need

only concern themselves with the public interface of that class. If you want to use a Queue or Stack class,

you shouldn't be concerned with (or need to be concerned with) how this class has been written. Whetherit uses a linked list, a statically sized array, or a dynamic array shouldn't influence whether and how you

use the class. Because you should be interested only in the public interface of a class, the Java

Developer's Kit includes a disassembler, javap, that can be used to display the public interface, both

methods and variables, of a class.

Additionally, the Java disassembler includes options to display private members or to display the actual

byte codes for the class's methods. This last option can be particularly useful if you want to achieve a

greater understanding of the byte codes used by the Java interpreter.

1.4.6.Header File Generator

Because Java is a new language and must fit in a world dominated by C and C++, included in Java is the

capability to use native C code within a Java class. One of the steps in doing this is using the Java header

file generator, javah.

1.4.7.JavaDoc

As programmers, we've fought it in every way possible. Unfortunately, there is no longer any excuse for

not documenting our source code. Using the JavaDoc utility provided with the Java Developers Kit, you

can easily generate documentation in the form of HTML files. To do this, you embed special comments

and tags in your source code and then process your code through JavaDoc. All of the on-line Java API

documentation was created with JavaDoc.

1.4.8.Applet Viewer

If you will be writing Java applets, you will definitely want to become familiar with the Applet Viewer.

This small program provides a real Java environment for testing applets. It loads the HTML file in which

the applet has been embedded and displays the application in a browser-like window.

CHAPTER-2

Introduction to JDBC

2.1 What is JDBC?

JDBC stands for "Java DataBase Connectivity". It is an API (Application Programming Interface) which

consists of a set of Java classes, interfaces and exceptions and a specification to which both JDBC driver

vendors and JDBC developers adhere when developing applications.

2.1.1.JDBC is a very popular data access standard.

RDBMS (Relational Database Management Systems) or third-party vendors develop drivers which

adhere to the JDBC specification. Other developers use these drivers to develop applications which access

those databases e.g. you'll use ConnectorJ JDBC driver to access MySQL database. Since the drivers

adhered to JDBC specification, the JDBC application developers can replace one driver for their

application with another better one without having to rewrite their application. If they had used some

proprietary API provided by some RDBMS vendor, they will not have been able to change the driver

and/or database without having to rewrite the complete application.

Who develops JDBC Specification?

SUN prepares and maintains the JDBC specification. Since JDBC is just a specification (suggestions for

writing and using JDBC drivers), third-party vendors develop JDBC drivers adhering to this specification.

JDBC developers then use these drivers to access data sources.

2.2.2.Why use JDBC?...

JDBC is there only to help you (a Java developer) develop data access applications without having to

learn and use proprietary APIs provided by different RDBMS vendors. You just have to learn JDBC and

then you can be sure that you'll be able to develop data access applications which can access different

RDBMS using different JDBC drivers.The purpose of this application is to introduce the concept of Java

Database Connectivity (JDBC) and illustrate the use of JDBC as a tool for database access. JDBC is a

mechanism that allows Java to communicate with databases using a standard Application Programming

Interface (API) to access databases regardless of the driver and the database product. This servlet-based

application provides the capability to connect to any relational database registered as an ODBC data

source using JDBC to browse the database meta-data and instance, and to manipulate the database by

issuing ad hoc SQL statements. The application can be run using a browser .

2.2.3.Registering an ODBC data source

To configure the ODBC data source implement the following steps:

1. Open the control panel from Windows settings and start the application "ODBC Data Sources

[32bit]"

NOTE: In Windows 2000, the Control Panel does not contain the pointer to the ODBC

DataSources". Using Help, search on ODBC and then select the topic "Using

Data Sources". From there, select "Data Sources" to bring up the ODBC .

2. Select the Add button to add a new data source.

4. Enter a string in the Data Source Name that you want to use to register your database, and click the

Database Select button.

5. Browse to find the actual file of your database and click OK when you're done.

6. Click OK to exit all the windows.

2.3.JDBC Architecture

We'll divide it into 2 parts:

*JDBC API (java.sql & javax.sql packages)

*JDBC Driver Types

2.3.1.JDBC API

The JDBC API is available in the java.sql and javax.sql packages. Following are important JDBC

classes, interfaces and exceptions in the java.sql package:DriverManager - Loads JDBC drivers in

memory. Can also be used to open connections to a data source. Connection - Represents a connection

with a data source. Is also used for creating Statement, PreparedStatement and CallableStatement objects.

Statement - Represents a static SQL statement. Can be used to retrieve ResultSet object/s.

PreparedStatement - Higher performance alternative to Statement object, represents a precompiled SQL

statement.

CallableStatement -Represents a stored procedure. Can be used to execute stored procedures in a

RDBMS which supports them.

ResultSet- Represents a database result set generated by using a SELECT SQL statement.

SQLException- An exception class which encapsulates database base access errors. javax.sql is part

of J2SE 1.4 and J2EE 1.3. It adds following features to JDBC in addition to the ones provided by java.sql

package.

DataSource- Abstracts a data source. This object can be used in place of DriverManager to efficiently

obtain data source connections (possibly using hidden connection pooling). Provides built-in connection

pooling.

XADataSource, XAConnection - Allows/supports distributed transactions. RowSet - It extends

ResultSet interface to add support for disconnected result sets.


13/31


13

2.4.JDBC Driver Types

There are 4 types of JDBC drivers. Commonest and most efficient of which are type 4 drivers. Here is the

description of each of them:

JDBC Type 1 Driver- They are JDBC-ODBC Bridge drivers. They delegate the work of data access

to ODBC API. They are the slowest of all. SUN provides a JDBC/ODBC driver implementation.

JDBC Type 2 Driver - They mainly use native API for data access and provide Java wrapper classes

to be able to be invoked using JDBC drivers.

Fig5.The Architectural Difference Between

Type1 and Type2 Drivers

While Type1 JDBC drivers offer convenience of access to ODBC data Sources, they are limited in their

functionality and performance.Type2 drivers are OS-specific and compiled and although they offer more

Java functionality and higher performance than Type1 drivers,still require a controlled environment
