Welcome to CSE 122: Introduction to Computer Programming II 🎉

What is this class? What will I learn?

Computing continues to play an ever-increasing role in today’s society. Having an understanding of computing is an essential skill for those in the 21st centry; from working in industries more reliant on technology, using computational methods to further scientific understanding, or being an informed citizen in a world with technology all around us.

This course is a second-level course in computer programming focused on the use of data structures and object oriented programming. It assumes students already have experience with some computer language and understand fundamental computing concepts such as control structures (loops and conditionals), variables, and arrays (see “Prior Experience and Expectations” for more details).

In this course, students will learn:

  1. Solving complex problems by decomposing them into smaller programming tasks, and assess the design trade-offs of particular solutions to these problems.
  2. The use of data structures such as lists, dictionaries, and sets to efficiently solve computational problems.
  3. Fundamental concepts in designing objected oriented programs to ensure abstraction between the interface of something and its implementation.
Prior Experience and Expectations

Prerequisite Material

This course is intended for students who already have some programming experience. Students entering CSE 122 should already be familiar with programming constructs for problem decomposition (methods or functions), control structures (loops and conditionals), variables and data types (such as integer data), and arrays or lists.

To better assess if CSE 122 is the right class for you, the Allen School has developed a Self-Guided Placement to help students assess which intro course is the right one for them to enroll in. Please see this website for more information on who to contact if you have questions about which introductory CSE course is the right course for you.

Programming Language

CSE 122 is taught in the Java programming language, but previous experience in Java is not expected to be successful in this course. Students who are familiar with another programming language will be provided with resources and tutorial to get up-to-speed with Java. If you would like to get started with practicing Java, please see our Java Tutorial.

If you want to learn more about the course and its policies, please check out our course syllabus.

Lessons

Anything listed in the “Lesson” materials for a day should be read before attending class that day. The Lessons are a first introduction to the most important terms and concepts for that day of class. It is okay if the Lesson doesn’t make complete sense as we have the rest of the class day to clarify the concepts, but if you don’t do the Lesson the class session won’t make any sense.
