The Java.util.concurrent.atomic.AtomicLong.lazySet() is an inbuilt method in java that updates the previous value and sets it to a new value which is passed in the parameter.
Syntax:
public final void lazySet(long newVal)
Parameters: The function accepts a single mandatory parameter newVal which is to be updated.
Return value: The function does not returns anything.
Below programs illustrate the above method:
Program 1:
// Java program that demonstrates // the lazySet() function import java.util.concurrent.atomic.AtomicLong; public class GFG { public static void main(String args[]) { // Initially value as 0 AtomicLong val = new AtomicLong( 0 ); System.out.println( "Previous value: " + val); val.lazySet( 10 ); // Prints the updated value System.out.println( "Current value: " + val); } } |
Previous value: 0 Current value: 10
Program 2:
// Java program that demonstrates // the lazySet() function import java.util.concurrent.atomic.AtomicLong; public class GFG { public static void main(String args[]) { // Initially value as 18 AtomicLong val = new AtomicLong( 18 ); System.out.println( "Previous value: " + val); val.lazySet( 200 ); // Prints the updated value System.out.println( "Current value: " + val); } } |
Previous value: 18 Current value: 200
