LongAdder class in Java creates a new adder with an initial sum of zero. The Java.LongAdder.decrement() is an inbuilt method in java that reduces the value by 1.
Syntax:
public void decrement()
Parameters: The function does not accepts any parameter.
Return value: The method do not returns any value.
Below programs demonstrate the above function:
Program 1:
// Java program to demonstrate// the LongAdder.decrement() 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 new value System.out.println("After addition" + " of 6, value is: " + num); // decrement operation on num num.decrement(); // Print after decrement System.out.println("After decrement, " + " value is: " + num); }} |
Output:
Initial value is: 0 After addition of 6, value is: 6 After decrement, value is: 5
Program 2:
// Java program to demonstrate// the LongAdder.decrement() 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 new value System.out.println("After addition" + " of 10, value is: " + num); // decrement operation on num num.decrement(); // Print after decrement System.out.println("After decrement, " + " value is: " + num); }} |
Output:
Initial value is: 0 After addition of 10, value is: 10 After decrement, value is: 9
