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
