For now I created a frame with gridlayout.
The problem is I can;t seem to figure out how to color the spaces between the squares, and I still need to add a tooltip to each square which should tell the mul of the specific square's row and col (rowxcol).

I don;t think I can do that for the frame so I am thinking about a panel
but the labels I add (as squares) are not shown...

this is my code:

import javax.swing.JLabel;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.LineBorder;

import java.awt.Color;
import java.awt.GridLayout;
import java.util.Scanner;

public class Program {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		ShowGridLayout frame = new ShowGridLayout();			
		frame.setTitle("ShowGridLayout");
		frame.setSize(300, 400);
		frame.setLocationRelativeTo(null); // Center the frame
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setAlwaysOnTop(true);		    
		frame.setVisible(true); 
	}

}

class ShowGridLayout extends JFrame    
{
	public ShowGridLayout()       
	{ 	

		Scanner scan=new Scanner(System.in);

		System.out.println("Please enter number of rows");		
		int rows=scan.nextInt();

		System.out.println("Please enter number of columns");		
		int cols=scan.nextInt();

		//Set GridLayout,rows,columns,gaps between components:horizontally,vertically

		//setLayout(new GridLayout(rows, cols, 5, 5));	   	   

		JPanel p1=new JPanel(new GridLayout(rows, cols));
		JLabel label;
		for(int i=0;i<rows;i++)
			for(int j=0;j<cols;j++)
			{					
				 label=new JLabel(i+","+j);
				label.setOpaque(true);	

				if((i+j)%2==0)
					label.setBackground(Color.yellow);	    	    
				else
					label.setBackground(Color.blue);	
				
				p1.add(label);
				
			}

				//				JLabel label=new JLabel(i+","+j);
				//				label.setOpaque(true);	
				//
				//				if((i+j)%2==0)
				//					label.setBackground(Color.yellow);	    	    
				//				else
				//					label.setBackground(Color.blue);	
				//
				//				add(label);
			//}


	}
}



in green is what I had previously (which worked) before I added the panel.
But I couldn;t add lines in between.
and yet again I am worried about the tooltip.

But adding the panel does not work and I don;t know why...

This doesn't sound related to Eclipse at all. You're probably better to
try stackoverflow.
