当第二次调用jframe类时，它复制它但没有jbuttons，jtextarea，jtextfield等只是jframe背景

标签： java swing jframe

我正在开展一个学校项目，我遇到一个问题，当我打电话给JFrame课时，每当我在中调用 simSimi.java 时mainMenu.java 起初它会完美地调用它而没有任何问题，但第二次调用 simSimi.java 或 mainMenu.java 时它会产生一个副本框架，但没有按钮，textarea等只是框架和背景，如果你帮助我解决这个问题，它真的会帮助我很多，谢谢：）

这是我调用mainMenu

的simSimi的代码 
//if(e.getSource()==play){
        simSimi ss = new simSimi();
        ss.setVisible(true);
        ss.setSize(420,500);
        ss.setLocation(300, 154); 
        ss.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        ss.setResizable(false);
        this.setVisible(false);
        dispose();
  }

这是simSimi的代码，当按下退出按钮时我调用mainMenu 

//if(e.getSource==exitButton){
mainMenu MM = new mainMenu();
MM.setVisible(true);
MM.setSize(719,480);
MM.setLocation(300, 154);
MM.setResizable(false); 
MM.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(false);
 this.dispose();
}

here's the simSimi

enter image description here

enter image description here here's the mainMenu

这是simSimi源代码

您需要做的第一件事就是停止制作所有内容static。在static扩展的任何类中删除所有JFrame个关键字。
