How to print an Array in Java without using Loop
  • Difficulty Level : Hard
  • Last Updated : 26 Aug, 2019

Given an array arr in Java, the task is to print the contents of this array.

Loop method: The first thing that comes to mind is to write a for loop from i = 0 to n, and print each element by arr[i].

for(int i = 0; i < Array.length; i++)
        System.out.println(Array[i]);

This article tells how to print this array in Java without the use of any loop.

For this, we will use toString() method of Arrays class in the util package of Java. This method helps us to get the String representation of the array. This string can be easily printed with the help of print() or println() method.

Example 1: This example demonstrate how to get the String representation of an array and print this String representation.






// Java program to get the String
// representation of an array and print it
  
import java.io.*;
import java.util.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        // Get the array
        int arr[]
            = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
  
        // Get the String representation of array
        String stringArr = Arrays.toString(arr);
  
        // print the String representation
        System.out.println("Array: " + stringArr);
    }
}
Output:
Array: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Example 2: This array can also be printed directly without creating a string.




// Java program to print an array
// without creating its String representation
  
import java.io.*;
import java.util.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        // Get the array
        int arr[]
            = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
  
        // Print the array
        System.out.println("Array: "
                           + Arrays.toString(arr));
    }
}
Output:
Array: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
