The lazySet() 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.setRelease(java.lang.Object…) to ensures that prior loads and stores are not reordered after this access.
Syntax:
public final void lazySet(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 lazySet() method:
Program 1:
// Java program to demonstrate// AtomicReferenceArray.lazySet() 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>(3); // set some value using lazySet() and print ref.lazySet(0, 1234); ref.lazySet(1, 4322); ref.lazySet(2, 2345); 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 program to demonstrate// AtomicReferenceArray.lazySet() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create an atomic reference object AtomicReferenceArray<String> HIMALAYAN_COUNTRY = new AtomicReferenceArray<String>(5); // set some value HIMALAYAN_COUNTRY.lazySet(0, "INDIA"); HIMALAYAN_COUNTRY.lazySet(1, "CHINA"); HIMALAYAN_COUNTRY.lazySet(2, "PAKISTAN"); HIMALAYAN_COUNTRY.lazySet(3, "BHUTAN"); HIMALAYAN_COUNTRY.lazySet(4, "NEPAL"); // print for (int i = 0; i < 5; i++) { System.out.println( HIMALAYAN_COUNTRY.get(i)); } }} |
