NetBeans IDE

|
|
- The above skeleton is created by the
IDE according to the information
provided before. Now you can add your
lines of code in the appropriate place of
the file. For our application, the line “//
TODO code application logic here”
has been replaced by the line “System.out.println(“Hello
World”);”
Finally, HelloWorld.java file will look like
the following:
/*
* HelloWorld.java
*
* Created on November 28, 2007, 2:31
PM
*
* To change this template, choose Tools |
Template Manager
* and open the template in the editor.
*/
package javajazzup;
/**
* This application displays “Hello World” to
the standard output.
*/
public class HelloWorld {
/** Creates a new instance of |
|
|
HelloWorld */
public HelloWorld() {
}
/**
* @param args the command line
arguments
*/
public static void main(String[] args) {
System.out.println(“Hello
World”);
}
} |
- Save the changes by choosing File-
>Save or pressing keyboard keys
Ctrl+S.
- Compile the source file by selecting
“Build -> Build Main Project” from
the main menu.
- The result of compilation appears in the
Output window as shown below:
If you get BUILD SUCCESSFUL
statement then you have compiled the
file successfully and if you get BUILD
FAILED then there may be any
syntactical error. Errors are shown in the
Output window as hyper-linked text.
Click the link to reach the place of error
in the code. Remove the error from the
code and compile it again. After
successful compilation of the code the
bytecode file HelloWorld.class is
generated which can be seen by
expanding the File window as shown
below:
