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



The java.util.Arrays.toString(double[]) method returns a string representation of the contents of the specified double array. The string representation consists of a list of the array’s elements, enclosed in square brackets (“[]”). Adjacent elements are separated by the characters “, ” (a comma followed by a space).


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

public static String toString(double[] a)


a − This is the array whose string representation to return.

Return Value

This method returns a string representation of a.




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 double array
      double[] d1 = new double[] { 1.9, 2.9, 3.4 };

      // let us print all the elements available in list
      System.out.println("The array is:");
      for (double number : d1) {
         System.out.println("Number = " + number);

      System.out.println("The string representation of array is:");

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

The array is:
Number = 1.9
Number = 2.9
Number = 3.4
The string representation of array is:
[1.9, 2.9, 3.4]
