Java-通过JButton调用方法 [英] Java - Call Method via JButton

问题描述

如何通过按JButton调用方法?

How can I call a method by pressing a JButton?

例如:

when JButton is pressed
hillClimb() is called;

我知道在按下JButton时如何显示消息等，但是想知道是否可以这样做?

I know how to display messages etc when pressing a JButton, but want to know if it is possible to do this?

非常感谢.

推荐答案

如果您知道如何在按下按钮时显示消息，那么您已经知道如何调用方法，因为打开新窗口就是对方法的调用.

If you know how to display messages when pressing a button, then you already know how to call a method as opening a new window is a call to a method.

有关更多详细信息，可以实现ActionListener，然后在JButton上使用addActionListener方法. 此处是有关如何编写.

With more details, you can implement an ActionListener and then use the addActionListener method on your JButton. Here is a pretty basic tutorial on how to write an ActionListener.

您也可以使用匿名类:

yourButton.addActionListener(new ActionListener() { 
    public void actionPerformed(ActionEvent e) { 
        hillClimb();
    } 
});
