In this final project you examine the SerialNumber class, which is used by the Home Software Company to validate software serial numbers. A valid software serial number is in the form LLLLL-DDDD-LLLL, where L indicates an alphabetic letter and D indicates a numeric digit. For example, WRXTQ-7786-PGVZ is a valid serial number. Notice that a serial number consists of three groups of characters, delimited by hyphens. The class extracts the three groups of characters and validates them.

The SerialNumber UML Class Diagram

The fields first, second, and third are used to hold the first, second, and third groups of characters in a serial number. The valid field is set to true by the constructor to indicate a valid serial number, or false to indicate an invalid serial number. The table below describes the class's methods.

SerialNumber class'sMethod Description

Constructor

The constructor accepts a string argument that contains a serial number. The string is tokenized, and its tokens are stored in the first second, and third fields. The validate method is called.

isValid

This method returns the value in the valid field.

validate

This method calls the isFirstGroupValid, isSecondGroupValid, and isThirdGroupValid methods to validate the first, second, and third fields

isFirstGroupValid

This method returns true if the value stored in the first field is valid. Otherwise, it returns false.

isSecondGroupValid

This method returns true if the value stored in the second field is valid. Otherwise, it returns false

isThirdGroupValid

This method returns true if the value stored in the third field is valid. Otherwise, it returns false.

A few items (hints) that you will need to consider for the SerialNumber Class;

• The constructor breaks a serial number into three groups and each group is validated. You will need to use the trim method to eliminate whitespace and the split method to tokenize the string and return the tokens to an array.
• The isValid method returns a boolean value indicating whether the serial number is valid.
• The validate method sets the valid field to true if the serial number is valid. Otherwise it sets valid to false.
• The isFirstGroupValid (and Second, and Third) method validates each group of characters or digits. You will need to check each groups length and if each character is a letter or a digit.
• A valid serial number must have three groups of characters, so an if statement should be used to determine whether the tokens array has three elements. If not, the valid field is set to false. Otherwise, the three tokens are assigned to the first, second, and third fields.
• Last, the validate method is called. The validate method calls the isFirstGroupValid, isSecondGroupValid, and isThirdGroupValid methods to validate the three groups of characters. In the end, the valid field will be set to true if the serial number is valid, or false otherwise.

In addition to creating the serial Number Class, you will also SerialNumberTester that tests four strings, 1 is Valid and 3 are invalid;

String serial1 = "GHTRJ-8975-AQWR";

String serial2 = "GHT7J-8975-AQWR";

String serial3 = "GHTRJ-8J75-AQWR";

String serial4 = "GHTRJ-8975-AQ2R";

Your program output should indicate whether the 4 strings are valid or invalid.

Final Project Guidelines and Canvas Submission

Your Final Project is to be completed as a Java Project from your NetBeans or IntelliJ IDE.

The Final Projectfile must include in the NetBeans or IntelliJ Comment Section;

1. Your Full Name and Date
2. Class Name and Number (IntroJava-CSIS293)
3. Final Project

The Final Projectfile name isto be submitted as lastname_SerialNumber.zip (e.g. trzos_SerialNumber.zip).You need to doing this when you creating a NetBeans or IntelliJ Project.

How to submit your Final Project

1. Navigate to your Project Folder Default location in Windows Explorer
2. Right Click on the folder and select Send to Compressed (zipped) folder
3. Upload your zipped Final Project file to Canvas

NetBeans and IntelliJ Download and Steps to creating Project

Important, Important, Important!!!!

If you are new to Java Development with NetBeans IDE 8.2 then you willneed you need to install the Java SE Development Kit (JDK)JDK 8u121.You can download the latest JDK here(Links to an external site.)

This is the best solution!!!

After you have downloaded NetBeans 8.2 Standard Edition (Java SE) along with the development kit, then follow the instructions for installing

1. After the download completes, run the installer.

• For Windows, the installer executable file has the .exe extension. Double-click the installer file to run it.
• At the Welcome page of the installation wizard, click next.
• At the License Agreement page, accept and click next.
• At the NetBeans IDE installation page, do the following;
• Accept the default installation directory or specify another directory
• At the Summary page, do the following:
• Verify that the list of components to be installed is correct.
• Select the Check for Updates check box if you want to check the Update Center for possible updates.
• Verify that you have adequate space on your system for the installation.
• Click Install to begin the installation.
• At the Setup Complete page, provide anonymous usage data if desired, and click Finish.

Steps to Creating New NetBeans Java Project
