Just a start-up example , let you get a rough idea how to init a desktop application:


import java.awt.Image;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;


public class TestJFrame {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		JFrame frame = new JFrame();
		JPanel panel = new JPanel();
		JButton button = new JButton();
		button.setText("im Paul");
		button.setSize(50, 50);
		button.addActionListener(new LoveListener(panel));
		panel.add("Center", button);
		frame.add(panel);
//		frame.show();
		//frame.setBounds(10, 10, 10, 10);
		//frame.pack();
		frame.setSize(100, 100);
		JFrame.setDefaultLookAndFeelDecorated(true);
		Image icon = Toolkit.getDefaultToolkit().getImage("icon.png");
		frame.setIconImage(icon);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setVisible(true);
	}
	
	static class LoveListener implements ActionListener{
		private JPanel panel;
		public LoveListener(JPanel panel){this.panel=panel;}
		@Override
		public void actionPerformed(ActionEvent e) {
			JOptionPane.showMessageDialog(panel, "Love Haohao!");
			System.out.println("Love Haohao!");
		}
		
	}
}
