AtomicReferenceArray getPlain() method in Java with Examples

  • Last Updated : 15 Jul, 2021

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

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

Java




// Java program to demonstrate
// AtomicReferenceArray.getPlain() method
  
import java.util.concurrent.atomic.*;
  
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, 987);
        array.set(1, 988);
        array.set(2, 989);
        array.set(3, 986);
  
        // get and print the value
        // using getPlain method
        for (int i = 0; i < 4; i++) {
  
            int value = array.getPlain(i);
            System.out.println("value at "
                               + i + " = "
                               + value);
        }
    }
}
Output:
value at 0 = 987
value at 1 = 988
value at 2 = 989
value at 3 = 986

Program 2: 
 

Java




// Java program to demonstrate
// AtomicReferenceArray.getPlain() method
  
import java.util.concurrent.atomic.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a array of Strings
        String[] names
            = { "AMAN", "AMAR", "SURAJ" };
  
        // create an atomic reference object.
        AtomicReferenceArray<String> array
            = new AtomicReferenceArray<String>(names);
  
        // get and print the value
        // using getPlain method
        for (int i = 0; i < array.length(); i++) {
  
            String value = array.getPlain(i);
            System.out.println("value at "
                               + i + " = "
                               + value);
        }
    }
}
Output:
value at 0 = AMAN
value at 1 = AMAR
value at 2 = SURAJ
