## Creating a low-resolution of the night sky (...help?)

Greetings everybody =)

My assignment: create a low resolution image of the night sky using +'s as stars and spaces as the space.
-have to use a 2 dimensional array
-can be any type of array
-choose 100 cells at random to be stars

problem: for some reason, I can't print out 100 stars but only 80 .. i've been working for a long time on this code with much frustration and with little progress..

```   UW PICO(tm) 4.10                                                                      File: assignment11.java

// Programs purpose: prints out low resolution image of a night sky, using +'s as stars and " " as space.
// Step 1: Create a 80 x 20 2 dimensional array.
// Step 2: Choose 100 random cells to become stars.
// Step 3: Print out the night sky using " " as space and +'s as stars.

public class assignment11
{
public static void main(String []args)
{
// List of variables
final int scaleOne = 80; // Scale of 80
final int scaleTwo = 20; // Scale of 20

// Create an 80 x 20 2 dimensional array
int[][] nightSky = new int[scaleOne][scaleTwo];

// Randomize 100 cells for the array
int randOne = (int)(Math.random()*scaleOne);
int randTwo = (int)(Math.random()*scaleTwo);

// Set the random 100 cells to be 0
nightSky[randOne][randTwo] = 0;

// Prints out the night sky
for(int row = 0; row < nightSky.length; row++)
{
// If the random 100 cells are 0
if(nightSky[randOne][randTwo] == 0)
{
// Display a star for each cell that is zero
System.out.print("+");
}
for(int col = 0; col < nightSky.length; col++)
{
// Print out a space for the rest of the cells
System.out.print(" ");
}
}
}
}```

I can't seem to find a problem in my code.. It looks like i done everything correctly.
when i try to increase the number of the math.random..., i get a arraysOutofbounds exception.. sigh
