How to Print an Array in Java Without using Loop?

Last Updated : 01 May, 2022

Given an array arr in Java, the task is to print the contents of this array without using any loop. First let's see the loop method.
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].
Pseudo Code:

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

Concept: We will be using the toString() method of the 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 the print() or println() method.
Example 1: This example demonstrates how to get the String representation of an array and print this String representation.

Java

// 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

// 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]
