Welcome to CSE 121: Introduction to Computer Programming I 🎉
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 century; 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 first course in computer programming focused on the basics of procedural programming in Java. It assumes students have not taken a previous programming course and do not have substantial other programming experience. (Students with previous experience are encouraged to consider CSE 122.)

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.
