Thread: Passing command line args from main to another class

Hello everyone.
As the title mentions, is this possible? I have been tasked with passing command line args from main to the class drawOnGrid. I will have to pass much more but figured starting here would help later on. Could someone show me an example? I would appreciate it and here is what I have.

import java.awt.*;
import javax.swing.*;
 
public class Tictactoe extends JFrame {
 
    //construct a figurePanel
    public Tictactoe() {
 
        Container RandomTicTacToePanel = getContentPane();
        RandomTicTacToePanel.setLayout(new GridLayout(3, 3));
 
 
        for (int i = 0; i < 9; i++) {
            RandomTicTacToePanel.add(new drawOnGrid());
        }
    }
 
    //Main method
    public static void main(String[] args) {
 
        Tictactoe Tframe = new Tictactoe();
        Tframe.setTitle("Tic Tac Toe Panel: Random Entries");
        Tframe.setSize(350, 350);
        Tframe.setResizable(true);
        Tframe.setLocationRelativeTo(null);
        Tframe.setVisible(true);
        Tframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
 
    class drawOnGrid extends JPanel {
 
        //overide the paintComponent
        @Override
        protected void paintComponent(Graphics g) {
            super.paintComponent(g);
 
            int random = (int) (Math.random() * 3);
 
            for (int i = 0; i < 3; i++) {
                for (int j = 0; j < 3; j++) {
 
                    if (random == 0) {
                        System.out.print(" ");
                    } else if (random == 1) {
                        g.drawOval(10, 10, getWidth() - 20, getHeight() - 20);
                    } else if (random == 2) {
                        g.drawLine(10, 10, getWidth() - 10, getHeight() - 10);
                        g.drawLine(getWidth() - 10, 10, 10, getHeight() - 10);
 
                    }
                }
 
            }
        }
    }
}

Use the normal way to pass an argument to any constructor or method: put the variable inside the ()s that follows the method's name.

Your code is full of method calls that pass args to methods.

Thanks Norm! Didn't really look at it that way.
