Practice Labtest 3 Solution

For those of you who tried it, here is a solution to Practice Labtest 3 from the main course website.

Test 1 and 2 Solution

Test 1
Test 2

Practice GUI Problem

Implement the Controller and Model found in this API. Download the GUI and View. Solutions are Model and Controller.

Practice Recursion Problems

Here are some practice recursion problems. Hints are here. Solutions are here.

PEx07 and PEx08 Solutions

No JavaDoc, but solutions for for PEx07 are here:
GUI.java
Controller.java
Model.java
View.java

PEx08 solution is here:
PEx08.java

Labtest 2 Material

This practice test is fairly comprehensive. It tests if you can extend an abstract base class, use an array as an attribute, and return a new array from a method.

Implement the class NamedPolynomial given its API. You will need the abstract base class NamedFunction.java and the partial implementation of NamedPolynomical.java. The solution is here. The methods setCoefficient, evaluate (non-array version), and toString are a little tricky.

Note that there is a different practice labtest on the main website for the course here. A solution (without Javadoc) is here.

Finally, the solution to PEx06 (missing Javadoc) is here.

Written Test 2 Material

Here are some practice written questions covering aggregation, composition, and some of the inheritance material.

Labtest 1 Material

There are APIs for three classes on the following link. Each API represents a separate practice labtest. The Vector3d API is probably too long for a labtest. You should also try generating the Javadoc for each API. Extra practice labtests

Testers are here for Book, and Hamster, and Vector3d. Note that the testers do not test any of the toString() or hashCode() methods. The testers are just .java files (they are clients of Book, Hamster, and Vector3d). If you put them in the same directories as your Book, Hamster, and Vector3d classes, you can get eclipse to recognize them by right-clicking on the package (book, hamster, and vector) and selecting Refresh from the pop-up menu.

Solutions are here for Book, and Hamster, and Vector3d.

Solutions for the practice labtest Computer are here and here. An undocumented version of the Monitor class is here so that you don't need the jar file from the practice test.

Solution for the practice labtest Transfer is here. I am not sure if the toString method was supposed to emulate the formatting of the picture of the transfer shown in the API; this solution assumes that toString was supposed to emulate the formatting. I think that getting the format correct would have been the most time consuming part of this test.
