The getAcquire() method of a AtomicReference class is used to return the value of this AtomicReference object with memory ordering effects on getting variable is compatible with memory_order_acquire ordering.
Syntax:
public final V getAcquire()
Parameters: This method accepts nothing.
Return value: This method returns the current value of this AtomicReference object with memory ordering effects.
Below programs illustrate the getAcquire() method:
Program 1:
Java
// Java program to demonstrate// AtomicReference.getAcquire() methodimport 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(1632798372); // apply getAcquire() and print value int value = ref.getAcquire(); System.out.println("value = " + value); }} |
Output:
Program 2:
Java
// Java program to demonstrate// AtomicReference.getAcquire() methodimport 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" + " LEARN AND APPLY"); // apply getAcquire and print value String value = ref.getAcquire(); System.out.println(value); }} |
