Java Float floatValue() Method

Java floatValue() method belongs to the Float class of the java.lang and is inherited from the Number Class. It is an instance method that returns the floating equivalent of the specified number.

It is generally an Unboxing method. Although after the introduction of Java 5, the conversion is done automatically(autoboxing), but it is important for you to know the concept of Boxing and Unboxing.

Unboxing: Conversion of a Float to float is referred to as the unboxing

Boxing: Conversion of an float to Float is referred to as boxing.


public float floatValue()  


No parameter is passed in this method.


Returns the floating value of the object after it is converted into the float.

Example 1:

Here, using the floatValue() function, the Float object is converted into its float equivalent.

import java.lang.Float;

public class StudyTonight 
    public static void main(String[] args) 
          Float n1 = 25.5f;  
          Float n2 = 46.2f;
          float i = n1.floatValue(); // returns the value of the Float object n1 as an float
          float j = n2.floatValue(); // returns the value of the Float object n2 as an float
          System.out.println("float value is " + i);  
          System.out.println("float value is " + j); 

float value is 25.5
float value is 46.2

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent float value.

import java.util.Scanner;  

public class StudyTonight
    public static void main(String[] args)
           System.out.print("Enter The Value ");  
           Scanner sc = new Scanner(;  
           Float f = sc.nextFloat();  
           Float n = f; 
           System.out.println("Float Value is: " + n.floatValue()); //Converting the Float object into float  
        catch(Exception e)
           System.out.println(" Invalid Input!!");

Enter The Value 352.4
Float Value is: 352.4
Enter The Value 0x77
Invalid Input!!
