Java Generics & Collections: Master the Fundamentals

Unlock the power of Java generics and collections in this comprehensive workshop! This session dives deep into type safety and efficient data handling in Java, equipping you with practical skills for real-world development.

What You'll Learn:

• Generics in Java: Understand what are generics and how the type erasure mechanism works within Java classes. Learn to leverage generic types for enhanced code reusability and type safety.
• Generic Classes: Discover how to create generic classes that can operate on various data types while maintaining type safety.
• Generic Interfaces: Learn to define generic interfaces that can be implemented by different classes working with diverse data types.
• Generic Methods: Master the creation of generic methods that can handle different data types without explicit type declarations.
• The Importance of Generics: Explore the benefits of using generics and the potential problems encountered without them.
• Wildcards: Gain proficiency in using unbounded wildcards and upper bound wildcards to constrain generic type parameters. Understand lower bound wildcards for more precise type restrictions.
• Advanced Generic Use Cases: Analyze complex examples of generic usage to solidify your understanding.

Collections in Java: A Deep Dive

• Collection Basics: A quick review of fundamental Java collections.
• Lists: Explore various list implementations including ArrayList, LinkedList, and more. Includes a summary with Bartek K.
• Sets: Learn about set implementations like HashSet, LinkedHashSet, and TreeSet.
• Maps: Master map implementations such as HashMap, LinkedHashMap, and TreeMap.
• Queues: Understand queue implementations including ArrayDeque, Stack, and PriorityQueue.
• Null Handling: Learn how to effectively manage null values within different collection types.

Sorting & Comparison

• Comparing Elements: Introduction to comparing elements within collections.
• Comparator Interface: Learn to implement the Comparator interface for custom object comparison.
• Comparable Interface: Understand how to use the Comparable interface for natural ordering of objects.

Big O Notation

• Big O Notation: Introduction to Big O notation for analyzing algorithm time and space complexity.

Project!

• Apply your newly acquired skills in a practical project demonstrating the use of generics and collections in Java.

Workshop Details:

• This workshop is based on Java 11. While the concepts are broadly applicable, the examples and tests are tailored for Java 11.
• This is the first workshop in the Zajavka path, designed to progressively build your Java programming skills.
• This workshop is an excellent opportunity to deepen your understanding of Java generics and collections.
• Practical exercises, tests, and a final project will provide valuable experience for your programming career.
