AtomicReferenceArray setOpaque() method in Java with Examples Last Updated : 03 Jan, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report The setOpaque() method of a AtomicReferenceArray class is used to set the value of the element at index i to newValue. Both index i and newValue are passed as parameters to the method. This method set the value with memory effects as specified by VarHandle.setOpaque(java.lang.Object...). In this way value is set in program order, but with no assurance of memory ordering effects with respect to other threads. Syntax: public final void setOpaque(int i, E newValue) Parameters: This method accepts: i which is an index of AtomicReferenceArray to perform the operation, newValue which is the new value to set. Return value: This method returns nothing. Below programs illustrate the setOpaque() method: Program 1: Java // Java program to demonstrate // setOpaque() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create an atomic reference object. AtomicReferenceArray<Integer> ref = new AtomicReferenceArray<Integer>(5); // set some value and print ref.setOpaque(0, 1324); ref.setOpaque(1, 144); ref.setOpaque(2, 322); System.out.println("Value of index 0 = " + ref.get(0)); System.out.println("Value of index 1 = " + ref.get(1)); System.out.println("Value of index 2 = " + ref.get(2)); } } Output: Program 2: Java // Java program to demonstrate // setOpaque() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create an atomic reference object.c AtomicReferenceArray<String> ref = new AtomicReferenceArray<String>(5); // set some value ref.setOpaque(0, "C"); ref.setOpaque(1, "PYTHON"); ref.setOpaque(2, "TS"); ref.setOpaque(3, "C++"); ref.setOpaque(4, "C"); // print for (int i = 0; i < 5; i++) { System.out.println(ref.get(i)); } } } Output: References: https://docs.oracle.com/javase/10/docs/api/java/util/concurrent/atomic/AtomicReferenceArray.html#setOpaque(int, E) Comment More infoAdvertise with us Next Article AtomicReference setOpaque() method in Java with Examples A AmanSingh2210 Follow Improve Article Tags : Java Java-Functions Java-util-concurrent-atomic package Java-AtomicReferenceArray Practice Tags : Java Similar Reads AtomicReference setOpaque() method in Java with Examples The setOpaque() method of a AtomicReference class is used to set the value of this AtomicReference object with memory effects as specified by VarHandle.setOpaque(java.lang.Object...).
