How could cb.setActionCommand(filename); be added to all of the 50 checkboxs through some method like below:

 for(int i = 0; i < checkboxes.length; i++) levels.add(checkboxes[i]);    //go through checkboxs and add them to levels

All the filenames start with kp  1-50 example (kp1.wav)


Total code below #2


#1
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;

public class MyClass4 extends JPanel {

ArrayList myArrayList = new ArrayList();

// Constructor
public MyClass4() {
// JPanel myPanel = new JPanel(); // No JPanel - why do we need it? I'M a JPanel...
setLayout(new GridLayout(0,3)); // Setting MY layout...
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;
JCheckBox check = new JCheckBox("" + n);

myArrayList.add(check);
add(check); // Adding it to ME
}
}
// myPanel.setLayout(new FlowLayout()); Why would I change the layout back to FlowLayout? All hell would break loose...
// add(myPanel); Don't need it at it's ME...
}
}


#2
// Create checkboxes, and group them in a CheckboxGroup to give them
    // "radio button" behavior.
    CheckboxGroup checkbox_group = new CheckboxGroup();
    Checkbox[] checkboxes = new Checkbox[3];
    checkboxes[0] = new Checkbox("Beginner", checkbox_group, true);
    checkboxes[1] = new Checkbox("Novice", checkbox_group, false);
    checkboxes[2] = new Checkbox("Intermediate", checkbox_group, false);
    checkboxes[3] = new Checkbox("Advanced", checkbox_group, false);
    checkboxes[4] = new Checkbox("Accomplished", checkbox_group, false);

    for(int i = 0; i < checkboxes.length; i++) levels.add(checkboxes[i]);//go through checkboxs and add them to levels

Something like:

for(int i = 0; i < checkboxes.length; i++) {
      checkboxes[i].setActionCommand("kp" + (i + 1) + ".wav");
      levels.add(checkboxes[i]);//go through checkboxs and add them to levels
}

CEHJ what is below was just for example. The #1 code is the code I will use. How would I name the checkboxs to add them?
 #2
// Create checkboxes, and group them in a CheckboxGroup to give them  // "radio button" behavior.
    CheckboxGroup checkbox_group = new CheckboxGroup();
    Checkbox[] checkboxes = new Checkbox[3];
    checkboxes[0] = new Checkbox("Beginner", checkbox_group, true);
    checkboxes[1] = new Checkbox("Novice", checkbox_group, false);
    checkboxes[2] = new Checkbox("Intermediate", checkbox_group, false);
    checkboxes[3] = new Checkbox("Advanced", checkbox_group, false);
    checkboxes[4] = new Checkbox("Accomplished", checkbox_group, false);

    for(int i = 0; i < checkboxes.length; i++) levels.add(checkboxes[i]);//go through checkboxs and add them to levels

You answered it. I was thinking that I had to name the group of checkboxs something, but I don't right. Because they are all seperate.
