AtomicReference lazySet() method in Java with Examples

  • Last Updated : 27 Dec, 2019

The lazySet() 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…) to ensures that prior loads and stores are not reordered after this access.

Syntax:

public final void lazySet(V newValue)

Parameters: This method accepts newValue which is the new value to set.

Return value: This method returns nothing.

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






// Java program to demonstrate
// AtomicReference.lazySet() method
import java.util.concurrent.atomic.AtomicReference;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create an atomic reference object.
        AtomicReference<Integer> ref
            = new AtomicReference<Integer>();
  
        // set some value using lazySet method
        ref.lazySet(67545678);
  
        // print value
        System.out.println("Integer value = "
                           + ref.get());
    }
}
Output:
Integer value = 67545678

Program 2:




// Java program to demonstrate
// AtomicReference.lazySet() 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 lazySet()
        ref.lazySet("GFG(GeeksForGeeks)");
  
        // print value
        System.out.println(ref.get());
    }
}
Output:
GFG(GeeksForGeeks)
