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 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:"); System.out.println(Arrays.toString(d1)); } }
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]
