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
