AtomicReferenceArray get() method in Java with Examples

Last Updated : 03 Jan, 2020

The get() method of a AtomicReferenceArray class is used to return the value of the element at index i for this AtomicReferenceArray object with memory semantics of reading as if the variable of index was declared volatile type of variable. Syntax:

public final E get(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 get() method: Program 1:

// Java program to demonstrate
// AtomicReferenceArray.get() 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, 12);
        array.set(1, 13);
        array.set(2, 14);
        array.set(3, 15);

        // get and print the value using get method
        for (int i = 0; i < 4; i++) {

            int value = array.get(i);
            System.out.println("value at "
                               + i + " = " + value);
        }
    }
}

 
// Java program to demonstrate
// AtomicReferenceArray.get() 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, 12);        array.set(1, 13);        array.set(2, 14);        array.set(3, 15);​        // get and print the value using get method        for (int i = 0; i < 4; i++) {​            int value = array.get(i);            System.out.println("value at "                               + i + " = " + value);        }    }}

Output:

value at 0 = 12
value at 1 = 13
value at 2 = 14
value at 3 = 15

Program 2:

// Java program to demonstrate
// AtomicReferenceArray.get() 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, "AMAN");
        array.set(1, "AMAR");

        // get and print the value using get method
        for (int i = 0; i < 2; i++) {

            String value = array.get(i);
            System.out.println("value at "
                               + i + " = " + value);
        }
    }
}
