I wrote a simple program with GUI. Ever time I run the program and close it, 
the invoked VM, javaw.exe, still keep alive in the memory.  These processes of 
javaw.exe won't be terminated until the Eclipse is closed.  The JDK I 
installed is jdk1.5.0.  The program I wrote as follows:

//-----------------------------------------------------------------------------
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class MyFrame extends JFrame implements ActionListener{
	private JButton button;
	private JLabel label;
	private String name[]={"A","B","C","D"};
	private int idx;
	
	public MyFrame(){		
		super("Test it!");
		
		idx=0;		
		Container c=getContentPane();
		c.setLayout(new FlowLayout(FlowLayout.CENTER));
		label=new JLabel(name[idx]);
		button=new JButton("push me!");
		label.setToolTipText("I am tips!");
		c.add(label);
		c.add(button);
		setSize(800,600);
		setVisible(true);
		button.addActionListener(this);
	}
	
	public static void main(String args[]){
		MyFrame app=new MyFrame();		
	}

	public void actionPerformed(ActionEvent e) {
		if(idx==3)
			idx=0;
		else
			idx++;
		
		label.setText(name[idx]);
		repaint();
	}
	
}

//-----------------------------------------------------------------------------
These processes of javaw.exe do slow down my computer a lot because they 
consume too much memory.
