java.lang.Float floatToIntBits(float value)


The floatToIntBits(float value) method returns true if the argument is a finite floating-point value; returns false otherwise (for NaN and infinity arguments).

Method Syntax

public static boolean isFinite(float f)

Method Argument

Data Type Parameter Description
float f the float value to be tested

Method Returns

The isFinite()  method of Float class returns true if the argument is a finite floating-point value, false otherwise.


Java 1.8


The method isFinite(float f) is simply a way to check if the method argument is a finite floating point. This is a very simple method of Float class however make note that this method is static. Thus it needs to be accessed statically which means that we should use this method in the format Float.isFinite(float f);

Java Float isFinite(float f) Example

Below is a simple java example on the usage of isFinite(float f) method of Float class.


import java.util.Scanner;

import static java.lang.System.*;

 * This example source code demonstrates the use of 
 * isFinite(float f) method of Float class.

public class FloatIsFiniteExample {

	public static void main(String[] args) {
		// Ask user input
		System.out.print("Enter Desired Value:");
		// declare the scanner object
		Scanner scan = new Scanner(;
		// use scanner to get value from user console
		Float userInput = scan.nextFloat();
		// close the scanner object
		// check if the float input is finite floating point
		boolean check = Float.isFinite(userInput);
		out.println("is the value entered finite? " + check);


Basically on the above example, we just ask for user input on the console and then we use the scanner object to get the float input. After that we assign the value to an Float wrapper class and we then we check if the user input is a finite floating point.
