ArrayIndexOutOfBoundsException

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1000
	at SortersTester.main(SortersTester.java:10)

Not sure why I'm getting this error. I'm trying to create arrays that gradually go up in size (start at 1,000 and increase by 1,000 each time until the last array created is 50,000) and fill them with random numbers between 1-1,000,000. Please help!

import java.util.Random;
public class SortersTester {
	public static void main (String[] args){
		Random r = new Random();
		for (int size=1000; size<=50000; size += 1000) {
			int [] anArray = new int[size];
			for (int i=0; i<=size; i++) {
				int randint = r.nextInt(1000000);
				anArray[i] = randint;
			}		

		}
	}
}

Hint: If an array has a size of 10, what will its last index be? Draw it out on paper.

Ah. So this:

for (int i=0; i<=size; i++) {

Should be this:

for (int i=0; i<size; i++) {

Correct? If so, thank you very much!

Yes that is correct.
