import java.awt.*;
public class ch4_5Jbutton extends JFrame{
	JButton btnText,btnImage,btnTextImage;
	JPanel pnlMain;
	public ch4_5Jbutton(){
		btnText=new JButton("退出(E)");
		btnText.setMnemonic('E');
		btnText.setToolTipText("退出系统");
		Icon logo=new ImageIcon("image1/1.gif");
		btnImage=new JButton(logo);
		btnTextImage=new JButton("退出（X）",logo);
		btnTextImage.setMnemonic('X');
		pnlMain=new JPanel();
		this.setContentPane(pnlMain);
		pnlMain.add(btnText);
		pnlMain.add(btnImage);
		pnlMain.add(btnTextImage);
		setTitle("JButton应有和演示");
		setSize(300,120);
