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);
        }
    }
}
