thanks for the Reply Json basically i have to modify my arrayUtil so it generates random chars im not too sure how to do it :S

Code :

---

import java.util.Random;
 
public class ArrayUtilOne
{
 
	public static int[] randomIntArray(int length, int n)
	{
		int[] a = new int[length];
		for (int i = 0; i < a.length; i++)
				a[i] = generator.nextInt(n);
		return a;
	}
	private static Random generator = new Random();
}
