Answer 1

import java.awt.FlowLayout;
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.JPasswordField;
import javax.swing.JTextField;

public class Login {

public static void main(String args[]) {
LoginFrm frame = new LoginFrm();
}
}

class LoginFrm extends JFrame implements ActionListener{
JLabel nameLabel=new JLabel("用户名：");
JLabel pwdLabel=new JLabel("密码：");
JTextField name=new JTextField(10);
JPasswordField password=new JPasswordField(10);
JButton butnSure=new JButton("确定");
JButton butnCancel=new JButton("取消");
public LoginFrm() {
super("登陆");
setBounds(500, 200, 280, 220);
setVisible(true);
setLayout(null);
nameLabel.setBounds(45, 20, 100, 25);
add(nameLabel);
add(name);
name.setBounds(105, 20, 110, 25);
add(pwdLabel);
pwdLabel.setBounds(45, 60, 100, 25);
add(password);
password.setBounds(105, 60, 110, 25);
add(butnSure);
butnSure.setBounds(45, 100, 80, 25);
add(butnCancel);
butnCancel.setBounds(135, 100, 80, 25);
butnSure.addActionListener(this);
butnCancel.addActionListener(this);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
validate();//刷新
}

public void actionPerformed(ActionEvent e) {
if (e.getSource() ==butnSure){
System.out.println("用户名："+name.getText());
System.out.println("密码："+name.getText());
if("admin".equals(name.getText().trim())&&"123".equals(password.getText().trim())){
this.dispose();
new MainFrm("用户界面",name.getText().trim(),password.getText().trim());
}else {
JOptionPane.showMessageDialog(this, "用户不存在");
}
}else if(e.getSource()==butnCancel){
System.exit(1);
}
}

class MainFrm extends JFrame{
private JLabel info;

public MainFrm(String s,String name,String password) {
super(s);
setBounds(400, 200, 500, 400);
setLayout(new FlowLayout());
info=new JLabel("登陆成功，用户名："+name+"，密码："+password);
add(info);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
validate();
}
}
}
