AtomicReferenceArray get() method in Java with Examples

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:

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);
        }
    }
}
