The java.DoubleAdder.toString() is an inbuilt method in java that returns the String representation of the sum() method. When the object of the class is created its initial value is zero.
Syntax:
public String toString()
Parameters: This method does not accepts any parameter.
Return Value: The method returns the string representation of the sum.
Below programs illustrate the above method:
Program 1:
// Program to demonstrate the toString() method import java.lang.*;import java.util.concurrent.atomic.DoubleAdder; public class GFG { public static void main(String args[]) { DoubleAdder num = new DoubleAdder(); // add operation on num num.add(42); num.add(10); // sum operation on num num.sum(); // Print after sum operation System.out.println(" the value after sum() is: " + num); // toString operation on variable num num.toString(); // Print after toString operation System.out.println("the value after toString() is: " + num); }} |
Output:
the value after sum() is: 52.0 the value after toString() is: 52.0
Program 2:
// Program to demonstrate the toString() method import java.lang.*;import java.util.concurrent.atomic.DoubleAdder; public class GFG { public static void main(String args[]) { DoubleAdder num = new DoubleAdder(); // add operation on num num.add(402); // sum operation on num num.sum(); // Print after sum operation System.out.println(" the value after sum() is: " + num); // toString operation on variable num num.toString(); // Print after toString operation System.out.println("the value after toString() is: " + num); }} |
Output:
the value after sum() is: 402.0 the value after toString() is: 402.0
