what is the simplest way to print a java array

To make things simple, convert the array to list and then print it.

Example

import java.util.Arrays;
import java.util.List;

public class Tester {
   public static void main(String[] args) {
      Integer[] numbers = {1,2,3,4,5};
      List<Integer> list = Arrays.asList(numbers);
      System.out.println(list);
   }
}

Output

[1,2,3,4,5]
