Need help with Java...

[XiS111]

Im not too fluent with Java programming, but my lecturer wanted me to do something with it to demonstrate algorithm of something like a cat and mouse chase...

so far i've managed to get a grid somewhat working with 1 error to get rid of, but cant seem to get a solution for it.

import java.awt.*;
import java.awt.event.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import java.util.*;

import javax.swing.JLabel;


class algorithm extends JLabel implements ActionListener
{

    private JFrame window = new JFrame("Cheetah Rabbit Game "); 			// creating window
    private static int R_Board;									//Change the number to set the grid size

	private JLabel [][]cell= new JLabel [R_Board][R_Board];
	private String letter="";
	private int count = 0;
	private int rowIn= 0;
	private int colIn =0;


public algorithm()
	{
		window.setSize(100*R_Board,100*R_Board);				//what size the window will appear
		window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		window.setLayout(new GridLayout(R_Board,R_Board));

                		for (int i=0;i<R_Board;i++)
		{
			for (int j=0;j<R_Board;j++)
			{
				cell[i][j] = new JLabel();
				cell[i][j].ActionListener();
				window.add(cell[i][j]);


				}
		}
	   window.setVisible(true);					//making the window visible


}
 public void actionPerformed(java.awt.event.ActionEvent a)
	{

		letter = "R";
		for (int x=0;x<R_Board;x++)
		{
			for (int y=0;y<R_Board;y++)
			{
				if(a.getSource()==cell[x][y])
				{
					cell[x][y].setText(letter);
					cell[x][y].setEnabled(true);
					rowIn=x;
					colIn=y;


					letter = "C";

			        { if(a.getSource()==cell[x][y])
							{
								cell[x][y].setText(letter);
								cell[x][y].setEnabled(true);
								rowIn=x;
								colIn=y;
							}

					    }

                    }
			    }
			}
}


}

Java is so highly frustrating... just this one error just wont go away no matter what i do (yes i've done my google searching and speaking to lecturers)

C:\Users\Chris\Desktop\Algorithm work\algorithm.java :35: cannot find symbol
symbol : method ActionListener()
location: class javax.swing.JLabel
cell[j].ActionListener();
^
1 error

Tool completed with exit code 1

Any help would be highly appreciated..

That error translates to: The method ActionListener() is undefined for the type JLabel

JLabel does not have a method called ActionListener.

What are you trying to do with this for loop?

for (int j=0;j<R_Board;j++) {
   celli][j] = new JLabel();
   cell[i][j].ActionListener();
   window.add(cell[i][j]);
}

You have an array that contains an array of JLabels, as RobH said

cell[i][j].ActionListener();

Doesn't make any sense?

Maybe he wants AddActionListener(); ?
