- Requirements / Prerequisites:
- Basic understanding of core Java syntax (variables, loops, methods, classes, objects).
- Familiarity with a Java Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.
- Java Development Kit (JDK) 8 or a newer version installed and properly configured.
- A strong eagerness to write efficient, modern, and high-quality Java code.
- No prior specific experience with the Collections Framework, Generics, Lambdas, or Stream API is required.
- Skills Covered / Tools Used:
- Strategic Data Structure Selection: Master choosing optimal collection types (e.g., Lists, Sets, Maps) for various performance needs.
- Robust Type Safety with Generics: Develop and apply Generics to prevent compile-time type errors and enhance code reliability.
- Functional Programming with Lambdas: Leverage Lambda expressions to write compact, readable, and functional code for operations.
- Declarative Data Processing with Stream API: Design and execute complex data transformations using powerful Stream operations (filter, map, reduce, collect).
- Deep JCF Hierarchy Understanding: Navigate the relationships and functionalities within the Collection and Map interfaces.
- Efficient Iteration: Utilize both `Iterable` and `Iterator` for controlled and unified collection element traversal.
- Hashing and Tree-Based Collections: Grasp the underlying mechanics of Hash Tables and Binary Trees for collections like `HashMap`, `HashSet`, `TreeMap`, `TreeSet`.
- Modern Code Refactoring: Transform traditional imperative loops into concise, high-performance Stream API pipelines.
- Performance Optimization Techniques: Learn to analyze and optimize collection usage and Stream operations for application efficiency.
- Problem-Solving with Functional Constructs: Apply Lambdas and Streams to simplify and elegantly solve complex data processing challenges.
