The get() method of a AtomicReference class is used to return the value of this AtomicReference object with memory semantics of reading as if the variable was declared volatile type of variable.
Syntax:
public final V get()
Parameters: This method accepts nothing.
Return value: This method returns current value of this AtomicReference.
Below programs illustrate the get() method:
Program 1:
// Java program to demonstrate// AtomicReference.get() 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        ref.set(12);          // get and print value        int value = ref.get();        System.out.println("value = " + value);    }} |
Output:
value = 12
Program 2:
// Java program to demonstrate// AtomicReference.get() 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("GEEKS FOR GEEKS");          // get and print value        String value = ref.get();        System.out.println("V = " + value);    }} |
Output:
V = GEEKS FOR GEEKS
