这样修改-

JButton btnNext = new JButton("Next");
btnNext.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {
        second_add second = new second_add();   
        setVisible(false); // Hide current frame
        second.setVisible(true);
    }
});

这样修改-

JButton btnNext = new JButton("Next");
btnNext.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {
        second_add second = new second_add();   
        setVisible(false); // Hide current frame
        second.setVisible(true);
    }
});

快速而肮脏的解决方案是在buttonclick操作中将第一帧的可见性设置为false，将第二帧的可见性设置为true。（见Sajal Dutta的回答）

但是，为了在超过2帧的情况下保持一致的行为，让每个帧都存储在主类（包含

main

方法和not扩展JFrame的类）的哈希表中，ID是帧的顺序（第一帧d1，第二帧：id2，等等）

然后创建一个静态方法

public void switchFrame(JFrame originatingFrame, int NextFrame){
    originatingFrame.this.setVisible(false);
    ((JFrame) myHashTable.get(NextFrame)).setVisible(true);
}

在主类中，可以使用

mainClass.switchFrame(this, IdOfFrameYouWantToGoTo);

这样，如果您想创建类似于向导的东西，还可以实现“后退”和“跳过”按钮

注意：我没有测试这段代码。这应该被看作是如何做到这一点的一般概述。
