1:登录界面代码：
import java.awt.BorderLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JButton;
import javax.swing.JPanel;
import javax.swing.WindowConstants;

public class Login extends javax.swing.JFrame {
private JPanel jPanel1;

private JButton bntOk;

public static void main(String[] args) {
Login inst = new Login();
inst.setLocationRelativeTo(null);
inst.setVisible(true);

}

public Login() {
super("登录界面");
initGUI();
}

private void initGUI() {
try {
setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
{
jPanel1 = new JPanel();
getContentPane().add(jPanel1, BorderLayout.CENTER);
jPanel1.setLayout(null);
{
bntOk = new JButton();
jPanel1.add(bntOk);
bntOk.setText("登录");
bntOk.setBounds(100, 141, 69, 30);
bntOk.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
Login.this.setVisible(false);
Main main = new Main();
main.setVisible(true);
}
});
}
}
pack();
setSize(400, 300);
} catch (Exception e) {
e.printStackTrace();
}
}

}

2：主界面：

import javax.swing.WindowConstants;

public class Main extends javax.swing.JFrame {

public Main() {
super("主界面");
initGUI();
}

private void initGUI() {
try {
setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
pack();
setSize(400, 300);
} catch (Exception e) {
e.printStackTrace();
}
}

}
