The Java.util.concurrent.atomic.AtomicLongArray.lazySet() is an inbuilt method in Java that eventually sets a given value at any given index of an AtomicLongArray. The method takes the index value of the AtomicLongArray and the value to set as the parameters and updates the previous value without returning anything.
Syntax:
public final void lazySet(int i, long newValue)
Parameters: The function takes two parameters:
Return Value: The function does not return any value.
Below programs illustrate the above method:
Program 1:
// Java program that demonstrates// the lazySet() 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 lazySet arr.lazySet(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 program that demonstrates// the lazySet() 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 lazySet arr.lazySet(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]
