AtomicLongArray addAndGet() method in Java with Examples Last Updated : 05 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The Java.util.concurrent.atomic.AtomicLongArray.addAndGet() is an inbuilt method in Java that atomically adds the given value to the element at an index of the AtomicLongArray. 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 long addAndGet(int i, long 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 long. Below programs illustrate the above method: Program 1: Java // Java program that demonstrates // the addAndGet() function import java.util.concurrent.atomic.AtomicLongArray; public class GFG { public static void main(String args[]) { // Initializing an array long a[] = { 10, 22, 33, 44, 55 }; // Initializing an AtomicLongArray with array a AtomicLongArray arr = new AtomicLongArray(a); // Displaying the AtomicLongArray System.out.println("The array : " + arr); // Index where value is to be added int idx = 0; // Value to add with value at idx long x = 16; // Updating the value at // idx applying addAndGet arr.addAndGet(idx, x); // Displaying the AtomicLongArray 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.AtomicLongArray; public class GFG { public static void main(String args[]) { // Initializing an array long a[] = { 1, 2, 3, 4, 5 }; // Initializing an AtomicLongArray with array a AtomicLongArray arr = new AtomicLongArray(a); // Displaying the AtomicLongArray System.out.println("The array : " + arr); // Index where value is to be added int idx = 3; // Value to add with value at idx long x = 16; // Updating the value at // idx applying addAndGet arr.addAndGet(idx, x); // Displaying the AtomicLongArray 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] Reference: https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicLongArray.html#addAndGet-int-long- Comment More infoAdvertise with us Next Article AtomicLongArray get() method in Java with Examples R rupesh_rao Follow Improve Article Tags : Java Java - util package Java-Functions Java-AtomicLongArray Practice Tags : Java Similar Reads AtomicLong addAndGet() method in Java with examples The Java.util.concurrent.atomic.AtomicLong.addandget() is an inbuilt method in java which adds the value which is passed in the parameter of the function to the previous value and returns the new updated value which is of data-type long.
