LongAccumulator toString() method in Java with Examples

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
