AtomicReference setRelease() method in Java with Examples

Last Updated : 27 Dec, 2019

The setRelease() method of a AtomicReference class is used to set the value of this AtomicReference object with memory effects as specified by VarHandle.setRelease(java.lang.Object...). This method has memory ordering effects compatible with memory_order_release ordering. Syntax:

public final void setRelease(V newValue)

Parameters: This method accepts newValue which is the new value to set. Return value: This method returns nothing. Below programs illustrate the setRelease() method: Program 1:

Java

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

import java.util.concurrent.atomic.AtomicReference;

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

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

        // set some value using setRelease method
        ref.setRelease(123457876L);

        // print value
        System.out.println("value = " + ref.get());
    }
}

Output:

Program 2:

Java

// Java program to demonstrate
// AtomicReference.setRelease() method
import java.util.concurrent.atomic.AtomicReference;

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

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

        // set some value using setRelease()
        ref.setRelease("String Builder");

        // print value
        System.out.println("Class = " + ref.get());
    }
}
