• The Java Technology consist of 3 entities;

• The Java Language

• A Runtime Environment

• A Set of tools


Set of Tools

Tools that are provided allow developers to create java programs.

Mainly they include the java compiler interpreter and other tools needed to develop, test and debug java programs.


Creating and Running Java Programs

Operating Instructions::.


Creating the Source File

• Use Windows Notepad or any other pure text editor


Loading Notepad

Start>>Programs>>Accessories>>NotepadOr Start>> Run>> Type Notepad Press Enter


Enter the Source Code Instructions4x:


Saving the Source Code

• Go to the required path to save• Enter the file name same as the main class

name with the extension .java• Surround both the file name and extension

within double quotes.

4x: “HelloWorld.java”

Hit the [SAVE] button


Like this.


Compiling the Source Code

• Java Provides a set of command line tool which can be used in building applications

• In order to compile a java source file, the path should be set,

• Once the path is correctly set the system can locate the necessary files or command line tools from the specified path.


Start the Command Prompt

Start>>Programs>>Accessories>>Command Prompt


Or Start it from the Run

Start >> Run >> Type CMD >> Press enter


Navigate to the Folder

• By using MS-DOS command you can go to the folder where you have saved the Java Source Files

• MS-DOS ( Discussion)


Compile the Program

Fix errors if any
