LongAdder class in Java creates a new adder with an initial sum of zero. The Java.LongAdder.floatValue() is an inbuilt method in java that returns the sum as a float value. When the object of the class is created its initial value is zero.
Syntax:
public float floatValue()
Parameters: The function does not accepts any parameter.
Return value: The method returns a float value which represents the sum of this LongAdder
Below programs demonstrate the above function:
Program 1:
// Java program to demonstrate// the LongAdder.floatValue() 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); // floatValue operation on num num.floatValue(); // Print after value System.out.println("Sum of LongAdder as float: " + num); }} |
Output:
Initial value is: 0 After addition of 6, value is: 6 After addition of 5, value is: 11 Sum of LongAdder as float: 11
Program 2:
// Java program to demonstrate// the LongAdder.floatValue() 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 100 to it num.add(100); // Print the final value System.out.println("After addition" + " of 100, value is: " + num); // floatValue operation on num num.floatValue(); // Print after value System.out.println("Sum of LongAdder as float: " + num); }} |
Output:
Initial value is: 0 After addition of 10, value is: 10 After addition of 100, value is: 110 Sum of LongAdder as float: 110
