Question: How to print values of an array in java?

We cannot print array elements directly in Java, you need to use Arrays. toString() or Arrays. deepToString() to print array elements. Use toString() method if you want to print a one-dimensional array and use deepToString() method if you want to print a two-dimensional or 3-dimensional array etc.

Quick Answer, how do you print the value of an array?

  1. public class PrintArray {
  2. public static void main(String[] args) {
  3. //Initialize array.
  4. int [] arr = new int [] {1, 2, 3, 4, 5};
  5. System. out. println(“Elements of given array: “);
  6. //Loop through the array by incrementing value of i.
  7. for (int i = 0; i < arr. length; i++) {
  8. System. out. print(arr[i] + ” “);
