在java中，如何通过单击按钮转到新框架？

我不熟悉java和实现GUI，我被卡住了。。。我必须在包含用户名和密码的框架上进行修改，当我点击提交时，我会被引导到另一个框架，即菜单，其中我有四个按钮，现在我想点击一个按钮并重定向到另一个框架，但我无法做到这一点。。。。请帮帮我

这是我的密码：

您需要以处理按下JButton的方式更改代码。您需要添加ActionListener以侦听按下的事件：

// make this class implements ActionListener
public class newframe extends imp implements ActionListener{

   JButton menu = new JButton("Customer");
   // add this as the action listener 
   menu.addActionListener(this);
}

这里是imp类：import java.awt.event.ActionEvent；导入javax.swing.JFrame；公共类imp扩展了JFrame{public imp（）{}public void isvisible（boolean t）{setVisible（t）；}}@MahNoor如果您有任何要添加到问题中的内容，而不是添加到问题中，请不要将其作为评论发布。
