Hello everyone out there, another question.

How could I get the numbers to start at 1 and end in 50
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...
for (int row=0; row<20; row++) {
for(int col=0; col<3; col++) {
JCheckBox check = new JCheckBox("" + (20*col+row));
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...
}
}
