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
