Modern Java Overview
Learn the newer Java features that make your code cleaner and more powerful. Use generic collections for type safety, lambdas and streams for better data processing, and JavaFX to create desktop applications with visual interfaces.
Generic Collections
Type-safe collections
Learn how to use Java Collections (like List, Set, and Map) with generic types (like List<Customer> and Map<Integer, Customer>) so the compiler can catch type errors early and you don’t need unsafe casts.
You'll learn: List<T>, Set<T>, Map<K,V>, diamond operator (<>), iterating safely over typed collections, and avoiding raw types in collection-based programs.
Lambdas & Streams
Functional programming in Java
Use lambda expressions and the Stream API to process collections more efficiently. Replace long loops with short, clear operations for filtering, mapping, and reducing data in your programs.
You'll learn: Lambda syntax, functional interfaces, stream operations like map/filter/reduce, method references, and processing data collections effectively.
JavaFX & GUI
Build desktop applications
Create desktop programs with graphical interfaces using JavaFX. Build interactive applications with buttons, text fields, layouts, and event handling for user-friendly software.
You'll learn: JavaFX components, scene structure, event handling, layouts, styling with CSS, and building complete desktop applications.
Start here: Begin with Generic Collections to understand type safety, then learn Lambdas & Streams for data processing. Finish with JavaFX & GUI to build visual applications. Complete the exercises after each topic—these features will make your Java code more effective and modern.
