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
