Actually I am gonna demonstrate the simple way to create the jar file which is a combination of multiple jars’ .
Requirements:

  • Firstly We need the NetBeans
  • JDK 1.6

(Also you can create a project where there is presence of jar files)

Let’s make a project File>New Project> …. and as your requirement you can make a project but there

is need of some extra jar files . If you are not familiar with adding jar files to Projects then ,

GUI (Graphical User Interface)

An applet is the software components or a small application which can run the program via JAVA programming Language.

Applets are on either desktop or on the web pages too.
The applets are mostly used for the GUI end user clients. The Applets are in GUI form.

Basically GUI is being used by the help of the JFrame which is located at the javax.swing

  • JPanel
  • JLabel
  • JButton
  • JTextField
  • and other classes ..

First of all if we are going to develop a small GUI program which can display the only the text;

[source language=’java’]
//import directives
import javax.swing.*;

public class Text1 extends JFrame{

public Text1() {
//FOR LABEL
JLabel label = new JLabel(“Hello JAVA !!!”);

//ADDING CONTAINERS TO COMPONENTS
this.getContentPane().add(label);
this.setSize(200,200);
this.setVisible(true);

}

public static void main (String[] args) {
// invoking constructor
new Text1();
}

}
[/source]
