AtomicLongArray set() method in Java with Examples Last Updated : 08 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The Java.util.concurrent.atomic.AtomicLongArray.set() is an inbuilt method in Java that sets a given value at any position of the AtomicLongArray. This method takes the index value of the AtomicLongArray as parameter and updates the value at that index. This method does not return any value. The function set() is similar to getAndSet() function but the former does not return any value while the latter returns the value at the given index before setting the new value at that index. Syntax: public final void set(int i, long newValue) Parameters: The function takes two parameters: i - The index value where the update is to be made. newValue - The new value to update at the index. Return Value: The function does not return any value. Below programs illustrate the above method: Program 1: Java // Java program that demonstrates // the set() 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; // The new value to update at idx long val = 10; // Updating the value at // idx applying set arr.set(idx, val); // Displaying the AtomicLongArray System.out.println("The array after update : " + arr); } } Output: The array : [1, 2, 3, 4, 5] The array after update : [10, 2, 3, 4, 5] Program 2: Java // Java program that demonstrates // the set() 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; // The new value to update at idx long val = 100; // Updating the value at // idx applying set arr.set(idx, val); // 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, 100, 5] Reference: https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicLongArray.html#set-int-long- Comment More infoAdvertise with us Next Article AtomicReferenceArray set() 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 set() method in Java with examples The Java.util.concurrent.atomic.AtomicLong.set() is an inbuilt method in java that updates the previous value and sets it to a new value which is passed in the parameter.
