Overview

This is an honors version of CS 2110/ENGRD 2110; credit is given for only one of CS 2110 and 2112. Transfer between CS 2110 and 2112 (in either direction) is encouraged during first three weeks. We cover intermediate software design and introduce some key computer science ideas. The topics are similar to those in CS 2110 but are covered in greater depth, with more challenging assignments. These topics include object-oriented programming, program structure and organization, program reasoning using specifications and invariants, recursion, design patterns, concurrent programming, graphical user interfaces, data structures, sorting and graph algorithms, asymptotic complexity, and simple algorithm analysis. Java is the principal programming language.

Prerequisites

Very good performance in CS 1110 or CS 1130 or equivalent course in Java or C++, or permission of the instructor. If you are unsure whether CS 2110 or CS 2112 is the right course for you, please talk to the instructor of either course. Both courses cover similar material and satisfy the same requirements, but CS 2112 covers material in more depth and has more challenging assignments. It is aimed at computer science majors.

Grading and submission policies

There will be about 7 assignments, mostly programming but also some written problems, totaling to 40% of your score. The first 2-3 assignments will be done solo; the final project will be done with a partner.

Assignment late penalties:

We are flexible about submitting assignments late. Unless otherwise specified, assignments may be turned in late with the following penalties applied to the score received:

  • 1 day late: 10%
  • 2 days late: 25%
  • 3 days late: 40%
  • >3 days late: 100%

Exams

There will be two prelims on October 2 and November 13. They will be 10% and 15% of total score respectively.

The final exam is during the final exam period (location and time TBD) and will be 30% of your score.

Other components

We expect you to participate in class and elsewhere. 5% of the score will be for participation (in-class, Piazza, course evals) and for in-class quizzes.

Resources

  • Java
  • Interactive development environments (IDEs)
  • Programming advice and resources
  • Computer labs
  • Support services

    • Java

    We will the use the Java 6 Standard Edition (Java SE 6) platform, which consists of the Java Development Kit (JDK) and the Java Runtime Environment (JRE). Java 7 is also ok, but we won't be using any features that are not available in Java 6. If you are using an earlier version than 6, please upgrade.

    To find out which version of the Java Runtime Environment (JRE) you are running, open a command window (in Windows, Start > Run... and type cmd, and in Mac OS X, Applications > Utilities > Terminal) and type java -version at the command prompt:

    C:\>java -version
java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) Client VM (build 20.2-b06, mixed mode, sharing)

    This says I have version 6 installed (6 and 1.6 are synonymous).

    If you are on a PC running Windows and have never installed a version of the Java Development Kit (JDK) on your machine, you probably don't have it. If you are on a Mac, you probably do. To find out, type javac -version:

    C:\>javac -version
javac 1.6.0_27

    If you get an error message or the version is earlier than 1.6, you must (re)install the JDK.

    Installing the JDK

    The JDK is already installed in CIT and ACCEL labs. However, installing it own your own machine will greatly facilitate your work. Please note that you should double check your work in a public lab, as privately owned machines occasionally exhibit different behaviors.

    Windows and Unix

    To download the JDK, visit Oracle's Java web site and download and install JDK 6 Update 27.

    Mac

    Oracle does not support Java for Macs. However, there is support available from Apple. If you are running Mac OS X version 10.4 (Tiger), 10.5 (Leopard) or 10.6 (Snow Leopard), your Mac already has the JDK installed. For 10.7 (Lion), you need to download and install it from here.

    Compiling and Running from the Command Line

    Compiling

    Say your main class is MyProgram and it is contained in the source file MyProgram.java. If it is not in a package, navigate to the folder containing MyProgram.java and type javac MyProgram.java.

    If it is in a package (say myPackage), the source should be in a folder called myPackage. Navigate to the folder containing myPackage and type javac myPackage/MyProgram.java.

    Running

    From the same folder you compiled from, type java MyProgram <program arguments> if it is not in a package, and java myPackage.MyProgram <program arguments> if it is.

    Specifying a Classpath

    Sometimes you may need to inform Java where to find auxiliary classes. You can do this with the -cp option to the java command. Supply a sequence of folders telling Java where to look for classes, separated by : (Mac) or ; (Windows).

    Brushing Up

    For students with limited Java experience, we recommend the online notes from CS 1130, Transition to Object-oriented Programming as a refresher. This is a self-paced course consisting of several modules that you can go through at your leisure.

    More Ways To Catch Up

    Local Software

    There are some basic Java utilities specifically for CS 2110 that you may find useful. These are contained in a package edu.cornell.cs.cs2110 contained in a .jar file which you can download from here. Follow the installation instructions on that page. Javadoc documentation is also available.

    IDEs

    IDE stands for integrated development environment. The use of an IDE is the best way to develop Java programs. IDEs provide many valuable aids such as syntax checking, debugging, and refactoring that can save you a lot of effort.

    There are many good IDEs. We recommend Eclipse, but you may use any one that you like, or none at all. Eclipse is installed in all the labs, along with some others. Early recitation sections will get you started with Eclipse if you are not familiar with an IDE.

    Here are some links:

    For consistency, the course staff use Eclipse with a common Java style. You can download the Eclipse style template here.

    Programming

    There are many valuable resources that can help you take your programming skills to the next level. Here are a few links:

    Computer Labs

    CIT Labs

    Cornell Information Technologies (CIT) runs several computer labs across campus for all members of the Cornell community. The JDK and Eclipse are installed on these machines. Check here for locations and times of operation.

    ACCEL Lab

    You can also find the course software in the Academic Computing Center (ACCEL), located in the Engineering Library in Carpenter Hall. Any CS student may register for an account.

    Support Services

    Academic Excellence Workshops

    The Academic Excellence Workshops (AEW) offer an opportunity for students to gain additional experience with course concepts in a cooperative learning environment. Research has shown that cooperative and collaborative methods promote higher grades, greater persistence, and deeper comprehension. The material presented in the workshop is at or above the level of the regular course. We do not require joining the AEW program, but do encourage students to join if they are seeking an exciting and fun way to learn. The AEW carries one S/U credit based on participation and attendance. The time commitment is two hours per week in the lab. No homework will be given. This is a wonderful opportunity for students to seek extra help on course topics in a small group setting.

    Your fellow undergraduate students, who are familiar with the course material, teach the sessions with material that they prepare. The course staff provide guidance and support but do not actually teach the AEW course content or any session. A representative from the AEW program will be speaking about the program and registration procedures in lecture.

    Your AEW liaison for this semester is Jason Zhao.

    See the AEW webpage for further information.
