AtomicReferenceArray getAcquire() method in Java with Examples

Last Updated : 19 Apr, 2023

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() method

import 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() method

import 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);
        }
    }
}
