ch4_4label.java

里面所含源码是本人平时做程序的一些实例

import javax.swing.*;
import java.awt.*;
public class ch4_4Label extends JFrame{
	JLabel lblPwd,lblImage,lblUser;
	JPanel pnlMain;
	JTextField txtName;
	JPasswordField pwdPassword;
	public ch4_4Label(){
		Toolkit tk=Toolkit.getDefaultToolkit();
		Image pic=tk.getImage("image1/25.gif");
		lblUser=new JLabel("用户名:");
		lblPwd=new JLabel("密码:");
		Icon logo=new ImageIcon("image1/1.gif");
		lblImage=new JLabel(logo);
		txtName=new JTextField(10);
		pwdPassword=new JPasswordField(10);
		pwdPassword.setEchoChar('*');
		//lblTextImage=new JLabel("混合标签",logo,JLabel.LEFT);
		pnlMain=new JPanel();
		this.setContentPane(pnlMain);
		pnlMain.add(lblUser);
		pnlMain.add(txtName);
		
		pnlMain.add(lblImage);
		pnlMain.add(lblPwd);
		pnlMain.add(pwdPassword);
		setTitle("应用演示");
		setIconImage(pic);
		setSize(50,200);
		setVisible(true);
	}
	public static void main(String args[]){
		new ch4_4Label();
	}
}
