Java.util.Arrays.toString(Object[]) Method

Description

The java.util.Arrays.toString(Object[] a) method returns a string representation of the contents of the specified Object array. If the array contains other arrays as elements, they are converted to strings by the Object.toString() method inherited from Object, which describes their identities rather than their contents.

Following is the declaration for java.util.Arrays.toString() method

public static String toString(Object[] a)

Parameters

Example

The following example shows the usage of java.util.Arrays.toString() method.

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {
   public static void main(String[] args) {

   // initializing Object array
   Object[] ob1 = new Object[] { 10, 20 };

   // let us print all the elements available in list
   System.out.println("The array is:");
   for (Object number : ob1) {
      System.out.println("Number = " + number);
   }
	
   System.out.println("The string representation of array is:");
   System.out.println(Arrays.toString(ob1));    
   }
}  

Let us compile and run the above program, this will produce the following result −

The array is:
Number = 10
Number = 20
The string representation of array is:
[10, 20]
