AtomicLongArray lazySet() method in Java with Examples
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]
