Java Float shortValue() method example

public short shortValue()

Note: This method overrides the method shortValue in class Number.

The shortValue() method of Float class returns the value of this Float as a short after a narrowing primitive conversion.

Java 1.1

The shortValue() method is used to transform this Float object to primitive short byte. This is basically the core functionality of this method. As we all know a float data type can have decimal digits, what will happen to that if we convert it to short? For example if we have the following expression: Float value = new Float(17.375f);. What will gonna happen is that, the decimal digit will get truncated if we use the floatValue method. What we mean we say the decimal digit will get truncated such that the value returned will be be 17.

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

package com.javatutorialhq.java.examples;

import java.util.Scanner;

import static java.lang.System.*;

/*
 * This example source code demonstrates the use of 
 * shortValue() method of Float class.
 */

public class FloatShortValueExample {

	public static void main(String[] args) {
		
		// Ask user input
		System.out.print("Enter Desired Value:");
		// declare the scanner object
		Scanner scan = new Scanner(System.in);
		// use scanner to get value from user console
		Float userInput = scan.nextFloat();
		// close the scanner object
		scan.close();		
		// convert the Float input to primitive short
		short value = userInput.shortValue();
		out.println("Value in short is " + value);
		
	}

}

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 get the value in primitive data type short using the shortValue() method of Float class.

Below is the sample output when you run the above example.
