Swing Java how to make multiple buttons That do different tasks on Click

I am a studying programming we just started Swing I have to make a simple boat management I need about 20 buttons. I am using the setVisible() method for every button I just wonder if is there another way of doing that. 

button.addActionListener(new ActionListener() 
            {
             public void actionPerformed(ActionEvent e) {
                button.setVisible(false);
                button1.setVisible(false);


                button2.setVisible(true);
                button3.setVisible(true);
            }
       });

If I understand your question, you could define two utility methods like

static void setVisible(JButton... btns) {
    for (JButton btn : btns) {
        btn.setVisible(true);
    }
}
static void setInvisible(JButton... btns) {
    for (JButton btn : btns) {
        btn.setVisible(false);
    }
}

Then you could call those with any number of buttons; like

setInvisible(button, button1);
setVisible(button2, button3);

As for making different buttons do different things, define an ActionListener per button (or per unique action).

You can just implement the action listener in your class like:

public class XYZ implements ActionListener

Then add it to your buttons like:

b1.addActionListener(this);
b2.addActionListener(this); 
...

Then override the actionPerformed method:

public void actionPerformed(ActionEvent e) {
    //Here do your tasks.
    // To identify the button, use : e.getSource();
}

Just add another new ActionListener(){....} to each button and modify the actionPerformed(ActionEvent e) method accordingly
