Integer floatValue() Method in Java (original) (raw)

Last Updated : 3 May, 2022

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);
}

}
