推荐答案
Kapilkp,
在同一时间,我做了类似的事情.
在登录JFrame中,您必须将关闭操作设置为:
Hi Kapilkp,
Same time ago, I did something like that.
In login JFrame you must set the close operation as:
f.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
然后,当您单击按钮时,就已经放置了该框架:
And when you click on the button, you have dispose this frame:
dispose();
并创建一个存储第二个JFrame的类的新实例
and create a new instance of your class that store the second JFrame
dispose();
JSecondFrame secondFrame = new JSecondFrame();
希望对您有帮助
最好的问候,

--UPDATE--
// MyLogin.java
import javax.swing.*;
import java.awt.event.*;
public class MyLogin {
private JFrame f = new JFrame("Login");
private JButton bok = new JButton("OK");
public MyLogin() {
f.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
f.getContentPane().add(bok);
bok.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
f.dispose();
new SecondFrame();
}
});
f.setSize(100,100);
f.setVisible(true);
}
public static void main(String[] args) {
new MyLogin();
}
}
// SecondFrame.java
import javax.swing.*;
public class SecondFrame {
private JFrame f = new JFrame("Second");
public SecondFrame() {
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(300,300);
f.setVisible(true);
}
}
登录JFrame只是一个按钮,当您单击它时,将放置登录窗口并显示第二个窗口.
The login JFrame is only a button and when you click it, the login window is disposed and the second window appears.
