The toString() method of a AtomicReferenceArray class is used to return the String representation of the current values of array.This method is used to represent the contents of AtomicReferenceArray as string
Syntax:
public String toString()
Parameters: This method accepts nothing.
Return value: This method returns the String representation of the current values of array.
Below programs illustrate the toString() method:
Program 1:
// Java program to demonstrate// toString() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create an atomic reference object. AtomicReferenceArray<Integer> ref = new AtomicReferenceArray<Integer>(5); // set some value ref.set(0, 234); ref.set(1, 134); ref.set(2, 325); // print the toString() return String toString = ref.toString(); System.out.println( "String representation of" + " AtomicReferenceArray:\n" + toString); }} |
Output:
String representation of AtomicReferenceArray: [234, 134, 325, null, null]
Program 2:
// Java program to demonstrate// toString() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create a array of Strings String[] names = { "AMAN", "AMAR", "SURAJ" }; // create an atomic reference object. AtomicReferenceArray<String> ref = new AtomicReferenceArray<String>(names); // print the toString() return String toString = ref.toString(); System.out.println( "String representation of" + " AtomicReferenceArray:\n" + toString); }} |
Output:
String representation of AtomicReferenceArray: [AMAN, AMAR, SURAJ]
