Course content
Topics from earlier classes
CS2110 course learning objectives
What’s the course all about? A quick tour

2. What’s CS2110 About? What do you think? From the Undergraduate Record:
A continuation of CS 1110, emphasizing modern software development methods. An introduction to the software development life cycle and processes. Topics include requirements analysis, specification, design, implementation, and verification. Emphasizes the role of the individual programmer in large software development projects.
I really ask them here! I expect to hear them talk about programming, Java.
Sometimes they talk about SW Engin like topics. That’s good.
In the first day I want to emphasize that it’s about more than programming and/or Java.

3. Better/replacement course description
A second course in computing and software development, with an emphasis both on modern software development and on principles central to computer science.
Topics related to software engineering include the development lifecycle, requirements analysis, specification, design, implementation, and verification.
Also addresses core computing principles such as abstraction, encapsulation, information hiding and recursion. More object-oriented programming techniques including inheritance, polymorphism, event-based programming.

4. Course Topics Object-Oriented programming: Modern PL features:
Abstraction, information hiding, recursive definitions
Design decisions, design for change and reuse
OO design: inheritance, polymorphism, etc.
Modern PL features:
Exceptions; streams
GUIs; Event-based programming
Networked programs
Concurrency, threads
Introduction to Software Development Practices:
Professional practices
Reading/writing specifications
Planning and designing programs
Debug and test
Basic documentation, standards, some maintenance
Use of tools
SW security

5. Course Objectives:
Upon successful completion of this course, students will:
Comprehend more advanced principles of object-oriented programming and how a programming language supports these, and apply these by developing larger and more complex programs than in their first programming course. (Topics include polymorphism, inheritance, collection classes, generics, etc.)
Comprehend and apply principles of design at the class and object level. These principles include abstraction, encapsulation, and information hiding. This also includes the ability to define and evaluate class interfaces to solve specified design problems, as well as the ability to understand, apply, and evaluate the use of reusable components to solve such problems.
I move through these pretty quickly. I note that they’re on the syllabus they have.
On this slide, I point out that:
#1 is about programming and OO.
#2 is about SW design principles (higher level than how to code Java).

6. Course Objectives:
Comprehend and analyze problems and programming issues such as dynamic memory management, indirect object references, and recursion. Also, be able to apply this knowledge by implementing software that includes these features.
Apply knowledge of software development practice to effectively use strategies, tools and environments such as interactive development environments, debuggers, testing frameworks, etc.
On this slide, I point out that:
#3 is about programming skills that apply to other languages besides Java.
#4 is about SW Engineering, programming in the large.

7. Course Objectives
Comprehend important basic concepts of software engineering and the development of large software systems, including the software lifecycle, requirements, design, and software quality. In their development activities, students will be able to apply basic unit testing and carry out a software inspection.
Comprehend the basic principles of the architecture of larger software systems, in particular object-oriented frameworks. Students will be able to apply this knowledge by developing a GUI using a framework.
On this slide, I point out that:
#5 is also about SW Engineering
#6 is too. This is a minor goal of the course.

8. Learning Sources Lectures and class activities Laboratories
Plan to attend!
Laboratories
You must enroll in one of Lab Sections ASAP
A textbook to read
Modern Software Development Using Java. (“MSD”)
2nd edition vs. 1st edition
Should have some Java reference text
See BOCM. One is on-line, free.
On-line resources: especially the Java API docs
Early in term: Javabat (

9. Necessary Background Pre-requisite (enforced!):
CS1110 at UVa (with a C- or better) or the equivalent
AP or IB exam counts
No university credit? Must take placement exam
First programming course in Java
Defining and using classes and objects
Loops and conditionals
No more than an overview of inheritance
Ability to use a Java development tool like JCreator, BlueJ, Eclipse
If you’re concerned, talk to me ASAP

10. Course Organization, Communication, etc.
Course web page:
Course TAs
One TA will be the Head TA for each lab-section
Like the instructor for the lab
Responsible for grade management (entering, reporting, updating)
More TAs will grade assignments and exams
Instructor’s role
Lectures, planning, course-design, student issues, etc.
Questions:
Send general questions to Collab Message board!
Send HW and grade questions to the staff:
Send your instructor on other things when appropriate
PLEASE include CS2110 in the subject line

12. Instructor Information
Prof. Tom Horton
Office: Olsson 228B. Phone:
Office hours: MWF 11am-noon; TTh 1:30-2:30pm

13. Laboratories
Lab activities are the central learning activity for CS2110
Sometimes a pre-lab activity. (Must do it!)
In lab: a lab exercise
Coding, group exercise, quiz, etc.
Graded on participation mostly
Programming Assignments AKA Homeworks
The “real” homework. Graded on quality.
Often done in pairs (according to certain rules).
Do outside of lab. Submit electronically.
Project(s): slightly larger assignments, done by groups of 4

14. Project Starts after Spring break Lasts 4 or 5 weeks Choice of project
Final week: demo in lab to TA
Choice of project
Instant Messenger Client
Android phone app
We have 25 Android phones for groups to use!
Project goals:
Put into practice SW Engineering knowledge
Create a significant application that’s fun and motivativing

15. Other Policies Etc. Honor Policy (read the course memo carefully)
It applies in CS2110!
Students and faculty at UVa should (re)commit to its principles and policies
See each assignment for rules about collaboration
Do not copy other people’s code! Do not give your code to others outside the rules!
Some assignments allow you to talk to classmates
This really shouldn’t lead to identical code, should it?
Violations: zero on the assignment, submission to the Honor Committee

16. Need Accommodation? Learning Needs (LNEC) students
Get in touch at least one week before an exam
If you need other things, contact me.
Any student who thinks s/he may qualify, contact the Learning Needs center
If you have an illness, trip, etc. that requires you to miss an exam or lab
Contact me in advance or as soon as possible
If you have any kind of issues that affect your attendance or performance, do not hesitate to contact me!

17. Expectations I expect you: You can expect me and the CS2110 team to:
To make your best effort
To prepare when required or do other activities
To come to class and do the readings
To let me know if there are problems or issues
You can expect me and the CS2110 team to:
Be objective and fair and understanding
To keep your informed about assignments and grades
To listen and respond when you make comments or suggestions
To make do my best to make this a good course

18. In-Class Activity In groups of 2-4, talk about the following things
Then, I’ll ask some groups to report to the class
First, share your name and major
Second, talk about what worries you about this class
Third, come up with at least 2 questions about the syllabus.
Go!
