Is this correct in that loop to add kp1.wav - kp50.wav tp the buttons

onOffButton.setActionCommand("kp" + (i + 1) + ".wav");


looprow : for (int row = 0; row < 20; row++)
          {
               for (int col = 0; col < 3; col++)
               {
                    int n = (20 * col + row + 1);
                    if (n > 50)
                    {
                         break looprow;
                    }
                    JButton onOffButton = new JColoredButton("" + n, Color.green, Color.black);
                    onOffButton.addActionListener(this);
                    onOffButton.setActionCommand("kp" + (i + 1) + ".wav");
                    gridPanel.add(onOffButton);
               }
          }

                  onOffButton.setActionCommand("kp" + (i + 1) + ".wav");

should be

                   onOffButton.setActionCommand("kp" + n + ".wav");

surely?

for (int i=1; i<=50; i++)
{
    JButton onOffButton = new JColoredButton(Integer.toString(i), Color.green, Color.black);
    onOffButton.addActionListener(this);
    onOffButton.setActionCommand("kp" + i + ".wav");
    gridPanel.add(onOffButton);
}

for (int i=1; i<=50; i++)
{
    JButton onOffButton = new JColoredButton(Integer.toString(i), Color.green, Color.black);
    onOffButton.addActionListener(this);
    onOffButton.setActionCommand("kp" + i + ".wav");
    gridPanel.add(onOffButton);
}
 
OK I can see the difference in the code, it does make more sense.

Thanks for the support,

objects  TimYates answer was correct to fit the code I posted isn't that correct. I need to pay better attention. I want to be fair about this. I really try to do this.
 
onOffButton.setActionCommand("kp" + n + ".wav");



looprow : for (int row = 0; row < 20; row++)
          {
               for (int col = 0; col < 3; col++)
               {
                    int n = (20 * col + row + 1);
                    if (n > 50)
                    {
                         break looprow;
                    }
                    JButton onOffButton = new JColoredButton("" + n, Color.green, Color.black);
                    onOffButton.addActionListener(this);
                    onOffButton.setActionCommand("kp" + (i + 1) + ".wav");
                    gridPanel.add(onOffButton);
               }
          }

I asked for this question to be reopened again. Because Tim Yates answered the question more precise to the code I posted. I have doubled the points to reward both of you for your answers.

Thanks for all the support,
