floatValue() method of Integer class present inside java.lang package is used to convert the value of the given Integer to a float type after a widening primitive conversion which in general is mostly applicable when we want to truncate or rounding-off the integer value. The package view is as follows:
--> java.lang Package
--> Integer Class
--> floatValue() Method
Syntax:
public float floatValue()
Return Type: A numeric value represented by this object after converting it to type float.
Note: This method is workable when it is supported by java version 1.2 or onwards, so make sure to update java version if running on older(introductory) java versions.
Example 1:
java
// Java Program to Demonstrate floatValue() Method// of Integer Class// Importing required classesimport java.lang.Integer;// Classclass GFG { // Main driver method public static void main(String args[]) { // Creating a custom integer by // creating object of Integer class Integer a = new Integer(28); // Converting Integer number to float value // using floatValue() method float b = a.floatValue(); // Printing the float value System.out.println(b); }} |
Output:
Example 2:
Java
// Java Program to Demonstrate Working of floatValue()// Method of Integer Class// Importing required classimport java.lang.Integer;// Classclass GFG { // Main driver method public static void main(String args[]) { // Creating a custom integer value by // declaring object of Integer Class Integer a = new Integer(20); // Convert Integer number to float value // using floatValue() method float b = a.floatValue(); // Printing the float value on console System.out.println(b); }} |
