Essential Java: Data Types, Collections, and Exceptions

Ready to move beyond basic Java syntax? To build real applications, you need to effectively manage data and gracefully handle unexpected errors. This course provides a solid foundation in Java's data handling and resilience capabilities. You'll go from understanding simple data types to building your own, organizing them in powerful data structures, and writing code that can anticipate and manage runtime problems. By the end, you'll be able to structure data efficiently and write more reliable, professional Java code. What you'll learn: - Understand Java's primitive types and their object wrapper classes. - Model custom data structures using classes, enums, and the modern `record` keyword for immutability. - Learn to use the Java Collections Framework, including Lists, Sets, and Maps with generics. - Practice fundamental error handling with `try-catch` blocks and learn the difference between checked and unchecked exceptions. - Organize your code effectively using packages for better maintainability. - Apply basic logging principles to track your application's behavior and diagnose issues. The course begins with the building blocks of data in Java, then moves into organizing groups of data with collections, and finishes by teaching you how to write robust, error-proof code through proper exception handling. This course is designed for beginners. No prior experience with data structures or advanced error handling in Java is required, just a basic familiarity with the language's syntax.
