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 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 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());
    }
}
