AtomicReference setOpaque() method in Java with Examples

Last Updated : 27 Dec, 2019

The setOpaque() method of a AtomicReference class is used to set the value of this AtomicReference object with memory effects as specified by VarHandle.setOpaque(java.lang.Object...). In this way value is set in program order, but with no assurance of memory ordering effects with respect to other threads. Syntax:

public final void setOpaque(V newValue)

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

Java

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

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

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

        // set some value using setOpaque method
        ref.setOpaque((float)9999.79);

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

Output:

Program 2:

Java

// Java program to demonstrate
// AtomicReference.setOpaque() 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 setOpaque()
        ref.setOpaque("CP Algos");

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

Output:
