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
