Tutorial 6

Due Saturday, June 14 at 6 am.

For this tutorial, you will add to the project that you created in Tutorial 3. If you did not do Tutorial 3, then review the steps for creating the project and adding files to it.

Activity One

Download these files to the ProgrammingActivitiesFiles directory that you created in Tutorial 3.

Before you modify the files, I want you to move them to a directory inside the Source Packages folder. Reivew these steps in Tutorial 3 for screen shots.

Right-click the Source Packages and select New -> Java Package.
Create a package that is named username.ch7.two (replace username with your webmail user name). Click Finish.
While holding down the control key, select all the 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 Refactor.
When you are done, you will see that all the files are in the new package.

Only edit the Airport.java file. Follow the instructions in the file. This is a summary of what is to be done.

Add a static variable for the count of airports.
Modify the constructors so they add one to the count.
Write a static accessor for the count variable.
Write the toString method. Include the static count.
Write the equals method. Do not inlcude the static count.

Run the AirportClient program to test your work. If there are errors, then make corrections in your class.

Activity Two

Download these files to the ProgrammingActivitiesFiles directory that you created in Tutorial 3.

Before you modify the files, I want you to move them to a directory inside the Source Packages folder. Reivew these steps in Tutorial 3 for screen shots.

Right-click the Source Packages and select New -> Java Package.
Create a package that is named username.ch9.two (replace username with your webmail user name). Click Finish.
While holding down the control key, select all the 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 Refactor.
When you are done, you will see that all the files are in the new package.

Only edit the ArrayListPractice.java file. Follow the instructions in the file. This is a summary of what is to be done.

In each method, access a predefined instance variable that is an ArrayList of Autos. Do not define the array list, it has been defined for you, even though you don't see it in the class.
Display the list of autos.
Set all the models in the array list to the same model. Use the string that is passed to the method as the model name for setting all the autos.
Find the maximum miles driven of all the autos in the array list.
Find the number of autos in the array list that have the model name that is passed to the method.
Clear all the autos from the list. The list will be empty after calling this method.
Remove the last element in the array list.

Run the ArrayListPractice program to test your work. If there are errors, then make corrections in your class.

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.
