AtomicLongArray decrementAndGet() method in Java with Examples Last Updated : 05 Feb, 2019 Comments Improve Suggest changes Like Article Like Report The Java.util.concurrent.atomic.AtomicLongArray.decrementAndGet() is an inbuilt method in Java that atomically decrements by one the element at a given index. 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 final long decrementAndGet(int i) Parameters: The function accepts a single parameter i which is the index where decrement by one operation is performed. 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 compareAndSet() 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 operation is performed int idx = 3; // Updating the value at // idx applying decrementAndGet arr.decrementAndGet(idx); // 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, 3, 5] Program 2: Java // Java program that demonstrates // the compareAndSet() 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 operation is performed int idx = 0; // Updating the value at // idx applying decrementAndGet arr.decrementAndGet(idx); // Displaying the AtomicLongArray System.out.println("The array after update : " + arr); } } Output: The array : [1, 2, 3, 4, 5] The array after update : [0, 2, 3, 4, 5] Reference: https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicLongArray.html#decrementAndGet-int- Comment More infoAdvertise with us Next Article AtomicLongArray decrementAndGet() method in Java with Examples rupesh_rao Follow Improve Article Tags : Java Java - util package Java-Functions Java-AtomicLongArray Practice Tags : Java Similar Reads AtomicIntegerArray decrementAndGet() method in Java with Examples The Java.util.concurrent.atomic.AtomicIntegerArray.decrementAndGet() is an inbuilt method in Java that atomically decrements by one the element at a given index.
