AtomicReference toString() method in Java with Examples

The toString() method of a AtomicReference class is used to return the String representation of the current value of AtomicReference object.

Syntax:

public String toString()

Parameters: This method accepts nothing.

Return value: This method returns the String representation of the current value.

Below programs illustrate the toString() method:
Program 1:

// Java program to demonstrate
// AtomicReference.toString() method

import java.util.concurrent.atomic.AtomicReference;

public class GFG {
    public static void main(String[] args)
    {

        // create an atomic reference object.
        AtomicReference<Double> ref
            = new AtomicReference<Double>();

        // set some value
        ref.set(1234.00);

        // apply toString()
        System.out.println("Value = "
                           + ref.toString());
    }
}

Output:

Value = 1234.0

Program 2:

// Java program to demonstrate
// AtomicReference.toString() method

import java.util.concurrent.atomic.AtomicReference;

public class GFG {
    public static void main(String[] args)
    {

        // create an atomic reference object
        // which stores String.
        AtomicReference<String> ref
            = new AtomicReference<String>();

        // set some value
        ref.set("GFG");

        // apply toString()
        System.out.println("Value  = "
                           + ref.toString());
    }
}

Output:

Value  = GFG
