AtomicLong set() method in Java with examples
The Java.util.concurrent.atomic.AtomicLong.set() 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 set(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 set() 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.set(10); // Prints the updated value System.out.println("Current value: " + val); }} |
Output:
Previous value: 0 Current value: 10
Program 2:
// Java program that demonstrates// the set() 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.set(200); // Prints the updated value System.out.println("Current value: " + val); }} |
Output:
Previous value: 18 Current value: 200
