The getAcquire() method of a AtomicReferenceArray class is used to return the value of the element at index i for this AtomicReferenceArray object with memory ordering effects compatible with memory_order_acquire ordering.
Syntax:
public final E getAcquire(int i)
Parameters: This method accepts the index i to get the value.
Return value: This method returns current value at index I.
Below programs illustrate the getAcquire() method:
Program 1:
Java
// Java program to demonstrate// AtomicReferenceArray.getAcquire() methodimport java.util.concurrent.atomic.AtomicReferenceArray;public class GFG { public static void main(String[] args) { // create an atomic reference array // object which stores Integer. AtomicReferenceArray<Integer> array = new AtomicReferenceArray<Integer>(5); // set some value in array array.set(0, 1213); array.set(1, 1344); array.set(2, 1453); array.set(3, 1452); // get and print the value // using getAcquire method for (int i = 0; i < 4; i++) { int value = array.getAcquire(i); System.out.println("value at " + i + " = " + value); } }} |
Output: 
Program 2:
Java
// Java program to demonstrate// AtomicReferenceArray.getAcquire() methodimport java.util.concurrent.atomic.AtomicReferenceArray;public class GFG { public static void main(String[] args) { // create an atomic reference array object // which stores String. AtomicReferenceArray<String> array = new AtomicReferenceArray<String>(5); // set some value in array array.set(0, "GEEKS"); array.set(1, "FOR"); array.set(2, "GEEKS"); // get and print the value using getAcquire method for (int i = 0; i < 2; i++) { String value = array.getAcquire(i); System.out.println("value at " + i + " = " + value); } }} |
