Java Programming 2 - Java Advanced Developer

Understand the structure and use of Java’s nested classes, including static, inner, local, and anonymous types. Learn how variable scope and shadowing behave within these contexts. You'll also gain fluency with lambda expressions and method references, enabling you to write more concise, expressive code - ideal for streamlining repetitive tasks and applying functional techniques in everyday Java development. 

Learn how to harness the power of Java Streams to process data declaratively. You’ll create streams from collections, apply intermediate operations like filtering and mapping, and use terminal operations such as collecting and reducing. The course also covers optional values, primitive streams, and stream chaining, helping you write cleaner, more efficient code for common data-processing tasks. 

Gain the skills to create modular applications in Java. Learn to migrate legacy codebases into modules, define and manage dependencies, and build modular services using the Java Platform Module System. This knowledge supports scalable application design and is key for developers working with large codebases or preparing for Java certification exams aligned to modular programming. 

Dive into advanced Java features that support real-world application development. Learn how to handle file I/O using both classic and NIO.2 approaches, create and use annotations, and write reflective code that adapts at runtime. You’ll also explore essential secure coding practices, from input validation to protecting sensitive data and defending against common Java security risks.
