AtomicReferenceArray setPlain() method in Java with Examples

The setPlain() method of a AtomicReferenceArray class is used to set the value of the element at index i to newValue. Both index i and newValue are passed as parameters to the method. This method set the value with memory semantics of setting as if the variable was declared non-volatile and non-final.

Syntax:

public final void setPlain(int i, E newValue)

Parameters: This method accepts:

• i which is an index of AtomicReferenceArray to perform the operation,
• newValue which is the new value to set.

Return value: This method returns nothing.

Below programs illustrate the setPlain() method:
Program 1:

// Java program to demonstrate
// setPlain() method

import java.util.concurrent.atomic.*;

public class GFG {

    public static void main(String[] args)
    {

        // create an atomic reference object.
        AtomicReferenceArray<Integer> ref
            = new AtomicReferenceArray<Integer>(5);

        // set some value and print
        ref.setPlain(0, 9876);
        ref.setPlain(1, 1234);
        ref.setPlain(2, 3212);

        System.out.println("Value of index 0 = "
                           + ref.get(0));
        System.out.println("Value of index 1 = "
                           + ref.get(1));
        System.out.println("Value of index 2 = "
                           + ref.get(2));
    }
}

Output:

Program 2:

// Java program to demonstrate
// setPlain() method

import java.util.concurrent.atomic.*;

public class GFG {

    public static void main(String[] args)
    {

        // create an atomic reference object
        AtomicReferenceArray<String> ref
            = new AtomicReferenceArray<String>(5);

        // set some value
        ref.setPlain(0, "JS");
        ref.setPlain(1, "EMBER");
        ref.setPlain(2, "REACT");
        ref.setPlain(3, "C++");
        ref.setPlain(4, "C");

        // print
        for (int i = 0; i < 5; i++) {
            System.out.println(ref.get(i));
        }
    }
}
