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
