100 Random, 2-digit, array elements.... help!!!!

Question

Hello. I need to populate an array with 100 random 2-digit elements, then, in a regular output window, print those elements on 10 separate lines, 10 elements per line.... After about 3-4 hours of failures with 'for', 'while', and 'if' statements, I admitted to myself that I am stumped. If anyone could help me out on this within the next 14-16 hours, I would greatly appreciate it.

here's what i've gotten so far:
import java.util.Random;
public class ArrayPopulation
final static int LIMIT = 10;
public static void main (String args [])
     Random generator = new Random ();
     int index = 0, index2 = 0;
     while (index < LIMIT)
          int random = generator.nextInt(99);
          if(random >= 10)
                  int[] TestScores = new int[random];
System.out.print (TestScores[index] + "
index] + "  ");
                   if (index > LIMIT && index2 < LIMIT)
System.out.println();
index2++;
          index++;
}my out put is always 0's for this, and i lost track
of the method that gave me numbers. unfortunately, it
is not printing 10 elements per line, not to mention
10 lines with 10 elements each line (totalling 100
elements). i'm going crazy because it is probobly
something small, but i really don't know at this
point.Well, one of the first problems you are having is that you are creating a new int array every time you execute the following line:
int[] TestScores = new int[random]The size of the new array is random and it is probably initializing to have all zeros in the array, which is why you print zeros.
You probably want to assign the value into an array, and keep the array around until it is populated. Then print it.
