I having a problem with Java GUI... PLEASE HELP ME!

Question

I try to create a radio button to get the size of my game board; but it didn't work and skipped right away to the other function(that logically creates the game board)...
(If you have more notices about my project, I would like to hear)

import java.util.Arrays;
import java.util.Scanner;

public class Rashi {
public static int N; //shura
public static int M; // amuda
public static int r; // random number
public static int index=0;
public static int []rand;//=new int[Rashi.N*Rashi.M];
public static int [][]logical;//=new int[Rashi.N][Rashi.M];

public static void main(String []args)
{
int ribe = CenteredFrame.inputR();//CenteredFrame.inputG();
M = ribe;
N = ribe;

rand=new int[Rashi.N*Rashi.M];
logical=new int[Rashi.N][Rashi.M];

Logical.makeBoard();
CenteredFrame board = new CenteredFrame();
board.show();

}

}
