What This Document Is
This document represents the foundational lecture material for a Computer Science I course (CSE 131) at Washington University in St. Louis. It serves as an introductory overview to the field of computer science and, specifically, the Java programming language. The lecture establishes core concepts and sets the stage for subsequent, more detailed explorations of programming principles. It’s designed to be the first in a series of lectures forming the basis of the course.
Why This Document Matters
This material is crucial for students beginning their journey into computer science. It’s particularly beneficial for those with little to no prior programming experience, as it aims to demystify the fundamental building blocks of how computers operate and how we instruct them to perform tasks. Students will find this lecture helpful as they begin to grasp the broader context of the course and understand the expectations for success. Reviewing this material *before* diving into hands-on coding exercises can significantly improve comprehension and retention.
Common Limitations or Challenges
This lecture provides a high-level introduction and does not delve into the specifics of coding syntax or implementation. It won’t teach you *how* to write Java programs, but rather *why* we use programming languages and *what* computers are capable of. It also assumes no prior knowledge but doesn’t offer a comprehensive review of prerequisite mathematical or logical concepts. It’s a starting point, not a complete guide.
What This Document Provides
* An overview of the course structure, including lectures, labs, and assessment methods.
* A foundational discussion of what computer science *is* and its relevance in modern society.
* A conceptual exploration of how computers function at a basic level, touching upon key components.
* An introduction to the Java programming language, including its history and current usage.
* An initial look at the development environment (Eclipse) that will be used throughout the course.
* Guidance on resources for seeking help and support, such as office hours and online forums.
