DoubleAdder reset() method in Java with Examples

The java.DoubleAdder.reset() is an inbuilt method in java that resets variables maintaining the sum to zero. When the object of the class is created its initial value is zero.

Syntax:

public void reset()

Parameters: This method does not accepts any parameter.

Return Value: The method returns the reset value.

Below programs illustrate the above method:

Program 1:

// Program to demonstrate the reset() 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); 
  
        // reset operation on variable num 
        num.reset(); 
  
        // Print after add operation 
        System.out.println(" the current value is: " + num); 
    } 
} 

Output:

the current value is: 0.0

Program 2:

// Program to demonstrate the reset() 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(10); 
  
        // reset operation on variable num 
        num.reset(); 
  
        // Print after add operation 
        System.out.println(" the current value is: " + num); 
    } 
} 

Output:

the current value is: 0.0
