Thread: Hello Family

Hey guys how are you all. I've created a program that displays my family's names in GUI. I decided now that i want to take it to the next level and have 2 command line arguments, the row and the column to display the names in a grid layout. I am not sure how to do this, i have converted the strings to Integers but don't know how to call them.

import java.awt.Container;
import java.awt.GridLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
 
// Program to display a greeting to family members.
public class HelloFamily extends JFrame
{
  // Constructor.
  public HelloFamily(noOfColumns, noOfRows)
  {
    setTitle("Hello Family");
    Container contents = getContentPane();
 
    // Family names to appear in one line.
    contents.setLayout(new GridLayout(0, noOfColumns, 10, 20));
 
    contents.add(new JLabel("Hello Shyam!"));
    contents.add(new JLabel("Hello Devesh!"));
    contents.add(new JLabel("Hello Dinesh!"));
    contents.add(new JLabel("Hello Ramila!"));
    contents.add(new JLabel("Hello Suresh!"));
    contents.add(new JLabel("Hello Vijya!"));
    contents.add(new JLabel("Hello Shashi!"));
    contents.add(new JLabel("Hello Manju!"));
    contents.add(new JLabel("Hello Premji!"));
    contents.add(new JLabel("Hello Kanta!"));
    contents.add(new JLabel("Hello Ronak!"));
    contents.add(new JLabel("Hello Rohini!"));
    contents.add(new JLabel("Hello Palvi!"));
    contents.add(new JLabel("Hello Jahanvi!"));
 
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    pack();
  } // HelloFamily
 
  // Create a HelloFamily and make it appear on screen.
  public static void main(String [] args)
  {
    int noOfColumns = Integer.parseInt(args[0]);
    int noOfRows = Integer.parseInt(args[1]);
 
    HelloFamily();
 
    HelloFamily theHelloFamily = new HelloFamily();
    theHelloFamily.setVisible(true);
  } // main
} // class HelloFamily

Any suggestions guys?

I would really appreciate it!

Kind regards

Shyam
