DoubleAccumulator floatValue() method in Java with Examples
The Java.DoubleAccumulator.floatValue() is an inbuilt method in java that returns the current value as an float after a narrowing primitive conversion. It means the initial datatype is double which is explicitly converted into type float.
Syntax:
public float floatValue()
Parameters: The function does not accepts any parameter.
Return value: The method returns the numeric value represented by this object after conversion to type float.
Below programs illustrate the above method:
Program 1:
// Java program to demonstrate the // floatValue() 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 ); // Print before floatValue operation System.out.println( "Old value is: " + num); // Print after floatValue operation System.out.println( "Current float value is: " + num.floatValue()); } } |
Output:
Old value is: 52.0 Current float value is: 52.0
Program 2:
// Java program to demonstrate the // floatValue() 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( 7 ); num.accumulate( 85 ); // Print before floatValue operation System.out.println( "Old value is: " + num); // Print after floatValue operation System.out.println( "Current float value is: " + num.floatValue()); } } |
Output:
Old value is: 92.0 Current float value is: 92.0
