将动作侦听器添加到netbeans中的按钮

Question

How to add an action listener to a button in netbeans

I tried to do that, but I don't know how

button.addactionlistener(null);

Answer 1

First you need to implement action listener in your class.

public class YourProject extends JFrame implements ActionListener{
yourbutton.addActionListener(this);

The you need to add the override method.

I hope this helps you.

Answer 2

YOu can also add by another way

JButton jb= new JButton("ok");

jb.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent ae)
      {System.out.println("You have clicked ok button");
    }
});
