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:
Return value: The function returns the updated value which is in Integer.
Below programs illustrate the above method:
Program 1:
// 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); } } |
The array : [10, 22, 33, 44, 55] The array after update : [26, 22, 33, 44, 55]
Program 2:
// 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); } } |
The array : [1, 2, 3, 4, 5] The array after update : [1, 2, 3, 20, 5]
