button6.java

本人在JAVA学习中的一点小实验

import java.awt.*;
import javax.swing.*;

public class button6 extends JFrame{
	JPanel p1,p2;
	JButton b11,b12,b13,b21,b22,b23;
	Container cp =null;
	
	public button6(){
    	this("No Title");;
	}
	public button6(String title){
  	 super(title);
     p1 = new JPanel();
     p2 = new JPanel();
     p1.setLayout(new FlowLayout());
     p2.setLayout(new FlowLayout());
     
     b11 = new JButton("Button 1");
     b12 = new JButton("Button 2");
     b13 = new JButton("Button 3");
     b21 = new JButton("Button 4");
     b22 = new JButton("Button 5");
     b23 = new JButton("Button 6");
     
     cp = getContentPane();
     cp.setLayout(new FlowLayout());
     p1.add(b11);p1.add(b12);p1.add(b13);
     p2.add(b21);p2.add(b22);p2.add(b23);
     
     cp.add(p1);cp.add(p2);
     
     setSize(400,240);
     setVisible(true); 
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   } 
  
  public static void main(String args[]){
  	new button6("GUI Demo");
  }
}
