AtomicReference set() method in Java with Examples
  • Last Updated : 27 Dec, 2019

The set() method of a AtomicReference class is used to set the value of this AtomicReference object with memory semantics of reading as if the variable was declared volatile type of variable.

Syntax:

public final void set(V newValue)

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

Return value: This method returns nothing.

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






// Java program to demonstrate
// AtomicReference.set() method
  
import java.util.concurrent.atomic.AtomicReference;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create an atomic reference object
        // which stores Integer.
        AtomicReference<Integer> ref
            = new AtomicReference<Integer>();
  
        // set some value using set method
        ref.set(13243546);
  
        // print value
        System.out.println("value 1 = " + ref.get());
    }
}
Output:
value 1 = 13243546

Program 2:




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