I want to print random Unicode characters in a JFRAME in java by using an infinite for loop.
I am a newbie in java programming and i hope the answer is not too complex.
this is the code so far-
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class Matrix extends JFrame
private static final int NUMBER_OF_REPS = 0;
public static void main(String[] args)
int a;
Random rand=new Random();
for(a=1;a>0;)
JLabel lbl=new JLabel();
lbl.setForeground(Color.GREEN);
lbl.setFont(new Font("MS Arial Unicode",Font.BOLD,12));
lbl.setText("\u30"+Integer.toHexString(rand.nextInt(96) + 160));
JFrame frame=new JFrame();
frame.setLocationRelativeTo(null);
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
frame.getContentPane().setBackground(Color.BLACK);
//error! lbl cannot be resolved to a variable
frame.getContentPane().add(lbl);
frame.getContentPane().setLayout(new FlowLayout());

General advice for new programmers: Break down your problem into smaller problems and focus on solving each independently. In this case, you can break it down into two problems: 1. Generate random Unicode characters with aforloop. 2. Create aJFrameand write text into it. Then, break down those problems into even smaller problems. This will help you learn in small steps and ask clear, concise questions. Good luck!

lblgoes out of scope at the end of the for-loop. Rewrite your code so that you can moveframe.getContentPane().add(lbl);inside the loop.

I used a while loop, they're easier for infinite numbers. As for JFRAME, you're going to want to look at another answer, as I'm not very good with javax.swing.* As of now it just puts it into the console
public Random random = new Random();
public static void main(String[] args)
while(true)
int i = random.nextInt(127);
System.out.print((char)i);
