Whole integer random, filling an array does not only produce integers

advertisements

I have code to fill an array with 10 integers but for some reason it is not only filling it with integers. EX. [I@5483cd or [I@1690726 Anyone know why?

public static void main(String[] args) {
    int[] array = new int[10];
    int length = array.length;

    for (int i = 0; i < length; i++) {
        array[i] = (int)(Math.random () * 10);
    }
    System.out.println(array);
}

System.out.println(array) is printing the hashcode for the array, not the values inside the array. Iterate over the values in the array and print those, like this:

for (int val : array)
{
   System.out.println(val);
}

Even simpler, use: Arrays.toString(array). See What's the simplest way to print a Java array?
