AtomicIntegerArray addAndGet() method in Java with Examples

Last Updated : 27 Feb, 2019

The Java.util.concurrent.atomic.AtomicIntegerArray.addAndGet() is an inbuilt method in Java that atomically adds the given value to the element at an index of the AtomicIntegerArray. This method takes the index value and the value to be added as the parameters and returns the updated value at this index. Syntax:

public int addAndGet(int i, int delta)

Parameters: The function accepts two parameters:

i - The index where value is to be added.

delta - The value to be added.

Return value: The function returns the updated value which is in Integer. Below programs illustrate the above method: Program 1:

Java

// Java program that demonstrates
// the addAndGet() function

import java.util.concurrent.atomic.AtomicIntegerArray;

public class GFG {
    public static void main(String args[])
    {
        // Initializing an array
        int a[] = { 10, 22, 33, 44, 55 };

        // Initializing an AtomicIntegerArray with array a
        AtomicIntegerArray arr = new AtomicIntegerArray(a);

        // Displaying the AtomicIntegerArray
        System.out.println("The array : " + arr);

        // Index where value is to be added
        int idx = 0;

        // Value to add with value at idx
        int x = 16;

        // Updating the value at
        // idx applying addAndGet
        arr.addAndGet(idx, x);

        // Displaying the AtomicIntegerArray
        System.out.println("The array after update : "
                           + arr);
    }
}

Output:

The array : [10, 22, 33, 44, 55]
The array after update : [26, 22, 33, 44, 55]

Program 2:

Java

// Java program that demonstrates
// the addAndGet() function

import java.util.concurrent.atomic.AtomicIntegerArray;

public class GFG {
    public static void main(String args[])
    {
        // Initializing an array
        int a[] = { 1, 2, 3, 4, 5 };

        // Initializing an AtomicIntegerArray with array a
        AtomicIntegerArray arr = new AtomicIntegerArray(a);

        // Displaying the AtomicIntegerArray
        System.out.println("The array : " + arr);

        // Index where value is to be added
        int idx = 3;

        // Value to add with value at idx
        int x = 16;

        // Updating the value at
        // idx applying addAndGet
        arr.addAndGet(idx, x);

        // Displaying the AtomicIntegerArray
        System.out.println("The array after update : "
                           + arr);
    }
}

Output:

The array : [1, 2, 3, 4, 5]
The array after update : [1, 2, 3, 20, 5]
