The Java.DoubleAccumulator.toString() is an inbuilt method in java that returns the String representation of the current value. Numeric value is explicitly converted to a string where the initial datatype is double.
Syntax:
public String toString()
Parameters: The method does not accepts any parameter.
Return Value: The method returns the string representation of the current value.
Below programs illustrate the above method:
Program 1:
// Java program to demonstrate// the toString() method import java.lang.*;import java.util.concurrent.atomic.DoubleAccumulator; public class GFG { public static void main(String args[]) { DoubleAccumulator num = new DoubleAccumulator( Double::sum, 0L); // accumulate operation on num num.accumulate(42); num.accumulate(10); // before toString the value is System.out.println("DoubleAccumulator: " + num.get()); // Print String representation System.out.println("String representation: " + num.toString()); }} |
Output:
DoubleAccumulator: 52.0 String representation: 52.0
Program 2:
// Java program to demonstrate// the toString() method import java.lang.*;import java.util.concurrent.atomic.DoubleAccumulator; public class GFG { public static void main(String args[]) { DoubleAccumulator num = new DoubleAccumulator( Double::sum, 0L); // accumulate operation on num num.accumulate(75); num.accumulate(1); // before toString the value is System.out.println("DoubleAccumulator: " + num.get()); // Print String representation System.out.println("String representation: " + num.toString()); }} |
Output:
DoubleAccumulator: 76.0 String representation: 76.0
