AtomicReference getAndSet() method in Java with Examples

// Java program to demonstrate
// AtomicReference.getAndSet() 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);

        // get and replace value
        double oldValue
            = ref.getAndSet((double)3213);

        // print
        System.out.println("OLD Value = "

                           + ref.get());
