Java Programming: Collections, Multithreading, and Streams

Java is one of the most widely used languages in software development, but moving beyond basic syntax requires a deep understanding of its core APIs and modern features. This course guides you step-by-step through essential Java mechanisms, giving you the skills to write clean, concurrent, and maintainable code. You will build a solid practical foundation in data processing, concurrency, and functional design patterns. What you'll learn: Understand key Java terminology, standard API architecture, and modern features like records. Master the Java Collections Framework to organize and manipulate data structures effectively. Process files and data streams using standard I/O and modern NIO libraries. Write responsive applications using multithreading and concurrency fundamentals. Apply functional programming techniques with lambda expressions and the Streams API. Parse string patterns and manage temporal data using regular expressions and the Date-Time API. The course begins with foundational definitions and fundamental concepts before progressing into standard library usage and written code walk-throughs. This material is ideal for beginner and intermediate developers who want to solidify their understanding of core Java tools through structured text explanations.
