The NetBeans IDE

CSIS 3701: Advanced Object Oriented Programming

Integrated Development Environment

• Single environment with tools for:– Generating and editing source code– Compiling and executing code– Testing and debugging code

• NetBeans IDE for Java– Available with Java from Sun (http://java.sun.com )– Available separately from http://www.netbeans.org – See “Homework 0” on course web site for more

details

NetBeans Organization

• Applications organized into projects– Contains all files associated with application

(source code, executables, testing, etc.)

• Projects contain packages– Groups of related files (like C++ libraries)

• Packages contain individual files– Each class in own file– Class is application if contains a main function

(can be executed in standalone mode)

Creating Projects

• Select File New Project

Creating Projects

• Choose Java as category and then Java Application

Creating Projects

• Give basic information about project– Project name– Where stored on computer

Automatically creates a “main” class with same name as project

Basic Project Structure

• Project listed on left

• Contains packages for that project

By default package with same name as project automatically created under Source Packages

• Package contains main class defined when project created

• Will see other packages besides source packages later (testing, etc.)

Editing a Class

• Source code written and edited in IDE• Color coded by type:

– Keywords blue– Identifiers green– Strings orange– Comments grey

Editing a Class

• Automatically checks syntax of class after every change• Syntax errors highlighted in red• Hints available on rollover

Compiling and Running a Project

• Can compile (“build”) and run from Run menu– Running automatically saves and compiles project

– Can use shortcut

Running a Project

• Code executed starting in main method of the main class• GUI output popped up in

separate window

• Text written to standard output displayed in “Output” tab on bottom of NetBeans window
