The exams are identical for all sections of CS 302. Here is the Exam Coverage.

Getting Help:

Aside from my office hours, there are also CS302 consultants on duty in 1370CS to answer questions and provide general help with your projects. Their hours are posted here.

Staying on top of things:

Check the Course Syllabus for the latest due dates, reading assignments, and other changes. Changes may also be communicated through the course email list, which is archived here: section 10, section 21.

Announcements

  • The Roster program, modified to read (and have ability to write) Students from a file in the specified format. Roster2.java. Example input file: roster1.txt

Examples

Note: the purpose of these examples is twofold: both to give you additional exposure to the course material as well as to allow you to download existing .java files, modify them, and experiment with the way the code works.

MIDTERM 2 REVIEW EXAMPLES (work in progress)
• ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
• Midterm conflict example from class. Illustrates boolean expressions. MidtermExample.java .
• If you need a review w/ boolean expressions, recall this LentilSoup.java. Tester shows example usage. LentilSoupMain.java
• ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
• Examples of common loop tasks. Contrasts do-while, while, and for. Includes a small menu program. Loops.java . Tester shows example usage. LoopUsage.java
• ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
• One-dimensional array examples. Arrays1D.java . Two-dimensional array examples. Arrays2D.java . Small sample tester provided. Practice fixing a bug in one of the above files. ArrayTests.java
• ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
• Vending Machine program from class: illustrates partially filled arrays and arrays of objects. VendMach.java . Tester includes some useful general review. VendTester.java
• ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

• ====================================================================================
• Program from the 1st day of class: computing the average. ComputeAverage.java .
• ====================================================================================
• Program that illustrates simple string manipulation. StringUsage.java .
• ====================================================================================
• Program that illustrates mathematical concepts you should know. Precision, implicit conversion vs. explicit casting, overflow and underflow. Precision.java , Conversion.java . Arithmetic.java .
• ====================================================================================
• The Point definition from class. This contains both the basic definition as well as both of the compareTo methods for Points (one instance and the other static). Point.java .
Also included a Tester class. PointMain.java .
• ====================================================================================
• Here is one solution to the Student exercise from the quiz: Student1.java .
Also included a Tester class. Student1Main.java .
• Here is an expanded solution that uses static: Student2.java .
Also included a Tester class. Student2Main.java .
• Here is a yet more expanded solution that uses Scanner and if/else: Student3.java .
Also included a Tester class. Student3Main.java .
• ====================================================================================
• An example of how to compare reference types (section 6.2 material). The Employee class has an equals() method that is used to compare two instances of Employee. Also illustrates String comparison. Employee.java .
• You may notice that an Employee has an Address. Here's the Address class definition. Address.java .
• A Tester class that shows the proper and erroneous ways to compare employees. EmployeeMain.java .
• A second tester class that illustrates aliasing in detail. Be sure you understand why the Employee class has a bug in this example, and what happens when EmployeeMain2 executes. EmployeeMain2.java .
• ====================================================================================
• An example I passed out last semester. It illustrates all of the static vs. instance, final vs. non-constant, public vs. private, and other important distinctions. Take a look if you want another example of these topics grouped into one class definition. Chair.java .
A Tester class is also provided. ChairMain.java .
