这是我的主要方法。

Answer 1

也许通过您的按钮单击或构造函数之一，您可以传递：

new BorrowSlipServer().setVisible(true);

同时还向 BorrowSlipServer(String s1,String s2) 添加了一些参数，以将您想要从 main 传递给它的任何内容传递给它。

仍然不清楚“链接”是什么意思，你想将东西从 MainMenu 传递到 BorrowSlipServer 还是相反？

在旁注中，您可能想添加：

setLocationRelativeTo(null);

这将使您的窗口在运行时居中，但请确保在设置帧大小后添加它。

Answer 2

尝试这个：

//add this button to the panel/frame of choice
JButton newLink= new JButton("New JFrame");
newFrame.addActionListener(new frameListener());

//put this listener class in file(s) you want to navigate in-between
private class frameListener() implements ActionListener
{
   public void ActionPerformed(ActionEvent e)
   {
        new NextJFrame();
   }
}
