LongAdder class in Java creates a new adder with an initial sum of zero. The Java.LongAdder.add() is an inbuilt method in java that adds the given value.
Syntax:
public void add(long x)
Parameters: The function accepts a single parameter x that specifies the value to be added.
Return value: The method do not returns any value.
Below programs demonstrate the above function:
Program 1:
// Java program to demonstrate// the LongAdder.add() method import java.lang.*;import java.util.concurrent.atomic.LongAdder; public class GFG { public static void main(String args[]) { // Initialized with 0 LongAdder num = new LongAdder(); // Print the initial value System.out.println("Initial value is: " + num); // Add 6 to it num.add(6); // Print the final value System.out.println("After addition" + " of 6, value is: " + num); // Add 5 to it num.add(5); // Print the final value System.out.println("After addition" + " of 5, value is: " + num); }} |
Output:
Initial value is: 0 After addition of 6, value is: 6 After addition of 5, value is: 11
Program 2:
// Java program to demonstrate// the LongAdder.add() method import java.lang.*;import java.util.concurrent.atomic.LongAdder; public class GFG { public static void main(String args[]) { // Initialized with 0 LongAdder num = new LongAdder(); // Print the initial value System.out.println("Initial value is: " + num); // Add 10 to it num.add(10); // Print the final value System.out.println("After addition" + " of 10, value is: " + num); // Add -5 to it num.add(-5); // Print the final value System.out.println("After addition" + " of -5, value is: " + num); }} |
Output:
Initial value is: 0 After addition of 10, value is: 10 After addition of -5, value is: 5
