[java] Help with code?-example incl. in post.

    
import java.util.*;

public class ArrayClass {
	String [] [] contents =new String[9][9];

	public void fill(){
		for (int i=0;i<9;i++){
			for (int j=0;j<9;j++) {
				contents[i][j]= "A";
			}
		}
	}

	public void print(){
		for (int i=0;i<9;i++){
			for (int j=0;j<9;j++) {
				System.out.print(contents[j]);
				if (j==8)
					System.out.println (" ");
			}
		}
	}

	public void mutate() {
		Random rand = new Random();
		int range=9;
		int x;
		int y;
		for (int mute=0;mute<6;mute++){
			x= (rand.nextInt(range));y=(rand.nextInt(range));
			contents[x] [y] = "*";
		}
	}

	public void getArray(String[][] secondArray) {
		for (int i=0;i<9;i++){
			for (int j=0;j<9;j++) {
				secondArray[i][j]= contents[i][j];
			}
		}
	}

	public static void main(String[] arguments) {
		ArrayClass poop = new ArrayClass();
		poop.fill();

		String[][] temp = new String[9][9];
		poop.getArray(temp);
		poop.contents[5][5]="7";
		poop.mutate ();
		for (int i=0;i<9;i++) {
			for (int j=0;j<9;j++) {
				System.out.print(temp[i][j]);
