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 classes
import java.lang.Integer;
// Class
class 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 class
import java.lang.Integer;
// Class
class 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);
}
}
