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);     } } |
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);     } } |
String representation of AtomicReferenceArray: [AMAN, AMAR, SURAJ]
