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
