如何将actionlistener添加到整个类而不将其单独分配给各个组件？

Question

For example, lets say I have 5 JButtons

b1 = new JButton("Add");
b2 = new JButton("Add 2");
b3 = new JButton("Find Connection");
b4 = new JButton("Read File");
b5 = new JButton("Exit");

If I want to add Actionlistener to all 5 buttons, I'd have to do this 5 times for each button.

b1.addActionListener(this);

Is there a way to add actionlistener to all JButtons in the class in one line of code? Or even better add actionlistener to every component in the class?

Answer 1

You could make a loop that adds the listener to the buttons.

    for(int i=0; i<5; i++)
{
    button[i].addActionListener(new ButtonListener());
}
