What will I learn?
Java Crash Course gives you fast, practical skills to build reliable console applications. You will learn core syntax, primitive types, operators, methods, arrays, and ArrayList, then practice text processing with the String API and basic Unicode handling. You will handle input safely with Scanner, validate data, avoid crashes, write clear comments, format console output, and package clean deliverables with a short README and version notes.
