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