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
