AtomicReference get() method in Java with Examples

Last Updated : 27 Dec, 2019

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

public final V get()

Parameters: This method accepts nothing. Return value: This method returns current value of this AtomicReference. Below programs illustrate the get() method: Program 1:

Java

// Java program to demonstrate
// AtomicReference.get() method

import 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(12);

        // get and print value
        int value = ref.get();
        System.out.println("value  = " + value);
    }
}

Output:

value  = 12

Program 2:

Java

// Java program to demonstrate
// AtomicReference.get() method

import 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("GEEKS FOR GEEKS");

        // get and print value
        String value = ref.get();
        System.out.println("V  = " + value);
    }
}

Output:

V  = GEEKS FOR GEEKS
