How to remove Java JButtons with a loop?

I am building a program in java and I was wondering if there is any function to remove a a list of JButtons when on is pressed?

This is what I have so far:

public void actionPerformed(ActionEvent e) {
    if(e.getSource() == button[0]) {
        for(int x = 0; x < 19; x++) {
            button[x].remove(this);

        }
    }
}

ActionListener is already configure and it works fine. Thank you in advance for who ever gives me a solution.

image  1)     JButton b[]=new JButton[10];
    for(int i=0;i<10;i++)
       {
            b[i]=new JButton(""+i);
            b[i].setBounds(i*10,i*20,20,20);
        add(b[i]);  
        }
    b[0].addActionListener(this);

adding Buttons on Frame and setting Action Listenr to b[0] button.

  image 2)  public void actionPerformed(ActionEvent e) {
            if(e.getSource() == b[0]) {
            for(int 1 = 0; 1 < 5; 1++) {
        remove(b[x]);
      }
     }
  }

Try this: 

public void actionPerformed(ActionEvent e) {
    if(e.getSource() == button[0]) {
        for(int x = 0; x < 19; x++) {
            button[x].getParent().remove(button[x]);

        }
    }
}

Your current code looks to be trying to remove something, your this, whatever it represents, from the JButton, which is bassackwards.

The key information to tell is -- remove the button from what? If a JPanel, then you must do just this, call remove(...) on the containing JPanel, passing in the component (the JButton) that you want to remove.

i.e.,

public void actionPerformed(ActionEvent e) {
  containingJPanel.remove((AbstractButton) e.getSource());
}

The specific code solution will depend on the structure of your current program.
