Java Programming 2 - Java Advanced Developer

Learn how to write robust, type-safe code using Java generics. You’ll explore generic classes and methods, bounded types, and type inference, before diving into Java’s core collection types. Understand when and how to use lists, sets, maps, and queues effectively, and develop key techniques for implementing hashCode, equals, compareTo, and Comparator properly to avoid common pitfalls in collection handling.  

Explore functional programming as it applies to modern Java. Understand the use of functions as first-class citizens and how to write pure and higher-order functions. Learn to apply Java’s built-in functional interfaces, compose functions effectively, and work with immutability to reduce side effects. These principles will help you write more predictable, maintainable, and efficient Java applications.  

Enhance your ability to write robust applications by creating and managing custom exceptions, using assertions appropriately, and applying structured error handling. You’ll also explore Java’s localisation features, including date/time formatting and resource bundles. This is especially useful if you’re developing applications for global audiences or working in environments that require robust, maintainable error and message handling.  

Understand how to design responsive, thread-safe Java applications. You’ll explore the fundamentals of Java threading, the memory model, and concurrency challenges such as race conditions and deadlocks. This course also covers how to implement synchronisation mechanisms and use tools like ExecutorService, thread pools, and parallel streams to improve performance while maintaining application stability and consistency.
