Java Float floatValue() method

The floatValue() method of Java Float class returns the float value of this object.

Syntax:

Parameters:

Return Value:

This method returns the float value of the argument.

Example 1

public class Float_floatValueMethod_Example1 {
    public static void main(String[] args) {

        Float f1=5f;

        System.out.println(f1);
        System.out.println( "Result after being converted to float value = "+f1.floatValue());

        //method would convert to float value

        Float f2 = new Float(5.7f);

        System.out.println("Result after being converted to float value = "+f2.floatValue());
    }

}

Test it Now

Output:

Result after being converted to float value = 5.0
Result after being converted to float value = 5.7

Example 2

public class Float_floatValueMethod_Example2 {
    public static void main(String[] args) {

        float f1=5f;

        Float  f2=f1.floatValue();

        System.out.println( "float value = "+f2);

        //this is the correct way of declaring Float class method

        Float f3 = new Float(5.7f);

        System.out.println("Result after being converted to float value = "+f3.floatValue());
    }

}

Test it Now

Output:

Error:(12, 21) java: float cannot be dereferenced

Here, float is a primitive data type. Its object can't be used to call Float class method. If you do so, it will give you an error.

Example 3

import java.lang.*;

public class Float_floatValueMethodExample3 {


        public static void main(String[] args) {

           //passing negative float value
            float f1 = -98797987876875698796.63655768769857694f;
            Float f2 =new Float(f1);
            //either call floatValue() method this way
            Float f3 = f2.floatValue();
            System.out.println("Float value = "+f3);


            //directly call the method in println function
            Float f4= new Float(-8276372f);
            System.out.println("Float value  = "+f4);
        }
    }

Test it Now

Output:

Float value = -9.879799E19
Float value  = -8276372.0
