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
