The java.DoubleAdder.floatValue() is an inbuilt method in java that returns the sum() as an float after a narrowing primitive conversion. When the object of the class is created its initial value is zero.
Syntax:
public float floatValue()
Parameters: This method does not accepts any parameter.
Return Value: The method returns the numeric value represented by this object after conversion to float data type.
Below programs illustrate the above method:
// Program to demonstrate the floatValue() method import java.lang.*;
import java.util.concurrent.atomic.DoubleAdder;
public class GFG {
public static void main(String args[])
{
DoubleAdder num = new DoubleAdder();
// add operation on num
num.add( 11 );
num.add( 10 );
// floatValue() operation on variable num
num.floatValue();
// Print after floatValue() operation
System.out.println( "the value after floatValue() is: " + num);
}
} |
Output:
the value after floatValue() is: 21.0
// Program to demonstrate the floatValue() method import java.lang.*;
import java.util.concurrent.atomic.DoubleAdder;
public class GFG {
public static void main(String args[])
{
DoubleAdder num = new DoubleAdder();
// add operation on num
num.add( 10 );
// floatValue() operation on variable num
num.floatValue();
// Print after floatValue() operation
System.out.println( "the value after floatValue() is: " + num);
}
} |
Output:
the value after floatValue() is: 10.0
