AtomicIntegerArray set() method in Java with Examples Last Updated : 27 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The Java.util.concurrent.atomic.AtomicIntegerArray.set() is an inbuilt method in Java that sets a given value at any position of the AtomicIntegerArray. This method takes the index value of the AtomicIntegerArray 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, int 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.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 operation is performed int idx = 0; // The new value to update at idx int val = 10; // Updating the value at // idx applying set arr.set(idx, val); // Displaying the AtomicIntegerArray 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.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 operation is performed int idx = 3; // The new value to update at idx int val = 100; // Updating the value at // idx applying set arr.set(idx, val); // 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, 100, 5] Reference: https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicIntegerArray.html#set-int-int- Comment More infoAdvertise with us Next Article AtomicInteger set() method in Java with examples G gopaldave Follow Improve Article Tags : Java Java-Functions Java-concurrent-package Java-AtomicIntegerArray Practice Tags : Java Similar Reads AtomicInteger set() method in Java with examples The java.util.concurrent.atomic.AtomicInteger.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.
