AtomicReferenceArray getOpaque() method in Java with Examples Last Updated : 02 Jun, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report The getOpaque() method of a AtomicReferenceArray class is used to return the value of the element at index i for this AtomicReferenceArray object with memory effects as specified by VarHandle.getOpaque(java.lang.Object...). This VarHandle.getOpaque(java.lang.Object...) method handles operation with no assurance of memory ordering effects with respect to other threads. Syntax: public final E getOpaque(int i) Parameters: This method accepts the index i to get the value. Return value: This method returns the current value at index i. Below programs illustrate the getOpaque() method: Program 1: Java // Java program to demonstrate // AtomicReferenceArray.getOpaque() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create an atomic reference array // object which stores Integer. AtomicReferenceArray<Integer> array = new AtomicReferenceArray<Integer>(5); // set some value in array array.set(0, 987); array.set(1, 988); array.set(2, 989); array.set(3, 986); // get and print the value // using getOpaque method for (int i = 0; i < 4; i++) { int value = array.getOpaque(i); System.out.println("value at " + i + " = " + value); } } } Output: Program 2: Java // Java program to demonstrate // AtomicReferenceArray.getOpaque() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create a array of Strings String[] names = { "AMAN", "AMAR", "SURAJ" }; // create an atomic reference object. AtomicReferenceArray<String> array = new AtomicReferenceArray<String>(names); // get and print the value // using getOpaque method for (int i = 0; i < array.length(); i++) { String value = array.getOpaque(i); System.out.println("value at " + i + " = " + value); } } } Output: References: https://docs.oracle.com/javase/10/docs/api/java/util/concurrent/atomic/AtomicReferenceArray.html#getOpaque(int) Comment More infoAdvertise with us Next Article AtomicReferenceArray getAndUpdate() 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 AtomicReferenceArray getAcquire() method in Java with Examples The getAcquire() method of a AtomicReferenceArray class is used to return the value of the element at index i for this AtomicReferenceArray object with memory ordering effects compatible with memory_order_acquire ordering.
