推荐答案

对于每个框架，您都可以设置一个默认按钮，该按钮将自动侦听Enter键.在该框架中按Enter键时，actionPerformed()方法将调用.

For each frame, you can set a default button that will automatically listen to the Enter key .When you hit enter in that frame, actionPerformed() method will be invoked.

frame.getRootPane().setDefaultButton(Button);

允许输入"键来按下提交按钮，而不是仅使用MouseClick
