DoubleAdder floatValue() method in Java with Examples

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
