The java.LongAccumulator.reset() is an inbuilt method in java that resets variables maintaining updates to the identity value.
Syntax:
public void reset()
Parameters: The 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.LongAccumulator; public class GFG { public static void main(String args[]) { LongAccumulator num = new LongAccumulator(Long::sum, 0L); // accumulate operation on num num.accumulate( 2 ); num.accumulate( 10 ); // resets current value num.reset(); // Print after reset operation System.out.println( " the current value is: " + num); } } |
the current value is: 0
Program 2:
// Program to demonstrate the reset() method import java.lang.*; import java.util.concurrent.atomic.LongAccumulator; public class GFG { public static void main(String args[]) { LongAccumulator num = new LongAccumulator(Long::sum, 0L); // accumulate operation on num num.accumulate( 42 ); num.accumulate( 10 ); // resets current value num.reset(); // Print after reset operation System.out.println( " the current value is: " + num); } } |
the current value is: 0
