The floatValue() method of Double class returns a float value of this double object.

Syntax

Parameters

Return value

The floatValue() method returns the double value converted to type float .

Example 1

public class Double_floatValueMethodExample1 {
    public static void main(String[] args) {

        Double double1 = 55.05587687687;

        Double double2= new Double(double1);

        //widening the float object

        float f1= double2.floatValue();

        System.out.println(double1+ " after converted to float becomes : "+f1);

    }

}

Output:

55.05587687687 after converted to float becomes : 55.055878

Example 2

import java.lang.*;
public class Double_floatValueMethodExample2 {
        public static void main(String[] args) {
            //passing negative integer

            double d1 = 98797987876875698796.63655768769857694;

            Double d2= new Double(d1);

            System.out.println("Double value = "+d2);

            //Converting Double into float

           float f1 =d2.floatValue();

            System.out.println("Float value  = "+f1);
        }
    }

Output:

Double value = 9.87979878768757E19
Float value  = 9.879799E19

Example 3

import java.lang.*;
public class Double_floatValueMethodExample3 {
        public static void main(String[] args) {

            double d1 = 98797987876875698796.63655768769857694;
            System.out.println("Double value = "+d1);

            //Converting Double into float

           float f1 =d1.floatValue();

            System.out.println("Float value  = "+f1);

        }

    }

Output:

Error:(19, 24) java: double cannot be dereferenced
