How do you pass variable values from one class to another?

[jbonifacejr]

I have two classes. One of them generates a random number and also creates an instance of a LabelFrame. I want the actual JLabel in the LabelFrame to display the value of the random number. Unfortunately, I can not figure out how to get to work. How do I pass the value of the random number generated in ShowTick.java to the JLabel in LabelFrame.java?

Here is my code..

ShowTick.java Text

import java.util.*;
import javax.swing.*;
import java.awt.FlowLayout;

public class ShowTick
{

public static void main (String[] args)
{
int iTick;
iTick = getTick();
System.out.println(iTick);

LabelFrame lf = new LabelFrame();
lf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
lf.setSize(275, 180);
lf.setVisible(true);

}

public static int getTick()
{
int intRet;
Random randomNumbers = new Random();
intRet = 1 + randomNumbers.nextInt(2);
return intRet;
}

}

LabelFrame.java text

import java.util.*;
import javax.swing.*;
import java.awt.FlowLayout;

public class LabelFrame extends JFrame
{
private JLabel label1;

public LabelFrame()
{

super("JLabel Test");
setLayout(new FlowLayout());

label1 = new JLabel("Lbl w/ text");
label1.setText("Hi");
add(label1);

}
}

Edit the line in ShowTick where I create the instance of the LabelFrame as follows:

LabelFrame lf = new LabelFrame(iTick);



In the LabelFrame class, edit the Public class so that it takes a parameter, then edit the label settext as follows:

public LabelFrame(int somenum)
label1.setText("" + somenum);

Now it works.
