AtomicReferenceArray toString() method in Java with Examples

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]
