Tutorial 3

Due May 24 at 6 am.

For this tutorial, you are to create a NetBeans project that will be used for the rest of the course. This project will contain all of the Programming Activities that you code from now on.

Activity One

Download these three files to a directory on your local computer. Name the directory ProgrammingActivitiesFiles.

Create a NetBeans project from these existing source files. Review the steps that you followed from Tutorial 2: Creating a NetBeans Project from Existing Sources

Before you modify the files, I want you to move them to a directory inside the Source Packages folder.

Right-click the Source Packages and select New -> Java Package.
Create a package that is named username.ch5.one (replace username with your webmail user name). Click Finish.
While holding down the control key, select all three files that are in the default package. Right-click on one of the highlighted files and select Cut.
Right-click on the new package that you created and select Paste -> Refactor Move. It is very important that you select Refactor Move and not just Move. When you refactor, it changes all the files that are affected by the move.
You will be asked to confirm what is to be refactored. Click Refractor.
When you are done, you will see that all the files are in the new package.

Open the PathClient.java file. Only make changes to the workWithIfElse method. Very Important: this is a method that has an int parameter named score. Do not create a variable named score, just use the parameter to the method.

Add an if...else block that implements what is explained in the comments in the program.
Be sure to do it in the exact order that is explained in the comments.
Par is 72. Run the program with values that are less than 72, equal to 72 and greater than 72.
If you do it correctly, the path that was followed will be shown to you graphically.
Be sure that all options in your logic are correct.

To run the PathClient.java file, right-click the name of the file and select Run.

Activity Two

In your operating system, navigate to the ProgrammingActivitiesFiles folder that you created in the first part of this tutorial.

You will see that you now have a directory structure that agrees with the package that you created, above.
Any changes to this folder will change the folders and packages that you have in NetBeans. As a matter of fact, a package in Java represents a folder in the operating system. This folder is the actual folder that corresponds to the package in NetBeans. You can work with the package in NetBeans or with the folder in the operating system.
Copy the files for Activity Two into the ProgrammingActivitiesFiles folder.
Go back to NetBeans and you will see that these files have been added to the default package. Create a new package named username.ch5.two (replace username with your webmail user name). There will now be two packages in the application. Follow similar steps as to those in part one of the tutorial and refactor the files that are in the default package into the username.ch5.two package.

Open the MultiPathClient.java file. Only make changes to the workWithSwitch method. Very Important: this is a method that has an int parameter named value. Do not create a variable named value, just use the parameter to the method.

Add a switch block that implements what is explained in the comments in the program.
For each case statement in the switch, do two things
1. Display a message dialog that contains a complete sentence that indicates what value the user entered.
2. Call the animate method, as is explained in the program comments.
Test your code with the values of all the case constants, as well as other values.

To run the MultiPathClient.java file, right-click the name of the file and select Run.

Submitting the Tutorial

To submit the tutorial, perform a Clean and Build on for the project. Be sure that you have followed the instructions for adding .java files to the JAR file before you do this step. If you are not sure, then review the steps in the Creating a NetBeans Project from Existing Sources page; it is in the section on Submitting Assignments.

You can verify that the JAR files are correct by clicking on the Files tab in NetBeans; open the project folder; open the dist folder; expand the JAR file. You should see the .class and .java files in the JAR. If you only see the .class files, then you need to review the instructions for adding the .java files. This is the same for NetBeans 5.5 and 6.

Using the operating system, not NetBeans, navigate to the dist directory for the project and upload the JAR file to me: Submit Assignment.
