To print an array, print each element in the array using a loop like the following:
public class Main { public static void main(String[] args) { int[] array = new int[5]; for (int i = 0; i < array.length; i++) { array[i] = (int)(Math.random() * 100); } //from w w w .j a v a2 s. c om for (int i = 0; i < array.length; i++) { System.out.print(array[i] + " "); } } }
