The java.LongAccumulator.toString() is an inbuilt method in java that returns the String representation of the current value of the LongAccumulator instance.
Syntax:
public String toString()
Parameters: This method does not accepts any parameter.
Return Value: This method returns the string representation of the current value.
Below programs illustrate the above method:
Program 1:
// Program to demonstrate the toString() 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); num.get(); // before toString the value is System.out.println(" the old value is: " + num); ; // toStrings current value num.toString(); // Print after toString operation System.out.println(" the current value is: " + num); }} |
Output:
the old value is: 52 the current value is: 52
Program 2:
// program to demonstrate the toString() 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(5); num.accumulate(10); num.get(); // before toString the value is System.out.println(" the old value is: " + num); // toStrings current value num.toString(); // Print after toString operation System.out.println(" the current value is: " + num); }} |
Output:
the old value is: 15 the current value is: 15
