Java Float shortValue Method

Introduction

The Java shortValue() method is used to convert a Float object to its corresponding short value. This lab will take you through step-by-step on how to use the shortValue() method in Java.

Create a new Java file

Create a new Java file using the command below:

touch FloatShortValue.java

Declare the import statements

The first thing you need to do is to declare the necessary import statements for the Float class. This is the class that contains the shortValue() method. Here is an example of how to declare the import statements:

import java.lang.Float;

Create a public class

After declaring the import statements, the next step is to create a public class. Here is an example of how to create a public class:

public class FloatShortValue {
}

Declare a main method

Now that you have created a public class, you need to declare the main method within the class. This is the method that will execute when you run the program. Here is an example of how to declare a main method:

public static void main(String[] args) {
}

Create a Float object

Inside the main method, you need to create a Float object. This is the object that you will be using to call the shortValue() method. Here is an example of how to create a Float object:

Float myFloat = new Float(3.14159f);

Call the shortValue() method

After creating the Float object, you need to call the shortValue() method on the object to convert it to a short value. Here is an example of how to call the shortValue() method:

short myShort = myFloat.shortValue();

Print the short value

Finally, you need to print the short value that was returned by the shortValue() method. Here is an example of how to print the short value:

System.out.println("The short value is " + myShort);

Compile and run the program

To compile and run the program, use the following commands:

javac FloatShortValue.java
java FloatShortValue

You should see the following output:

The short value is 3

Summary

Congratulations! You have successfully learned how to use the Java shortValue() method to convert a Float object to a short value. By following the steps in this lab, you can easily use the shortValue() method in your own Java programs.
