Whether you are preparing for a technical interview, looking to improve your coding skills, or aiming to optimize your Java applications, this course will provide the knowledge and hands-on experience needed to excel.

Module 1: Introduction to Collections

• Lay a solid foundation by understanding the core concepts of Java collections, making it easier to implement more advanced topics later.

• Understand the Collection Framework and learn how it can enhance your Java programming efficiency.

• Get familiar with Map collections, arrays, and the benefits of using generics, which will help you write safer, more efficient code.

Module 2: Core Interfaces of the Collection Framework

• Master Java's core interfaces such as List, Set, Queue, and Map, which are key to handling data effectively in real-world applications.

• Learn about essential methods like Iterator, forEach(), and spliterator(), and how they enable better data traversal.

• Gain a strong understanding of List and Set interfaces, so you can choose the best data structure for your applications.

Module 3: Collection Classes and Implementations

• Understand how to implement collections using ArrayList, LinkedList, HashSet, TreeSet, and others, and know when to use each for maximum performance.

• Learn thread-safe collections like Vector and Stack for scenarios where multi-threading is necessary.

• Develop an intuition for choosing the right collection class based on your application's requirements, optimizing both speed and memory usage.

Module 4: Advanced Concepts

• Master advanced topics like synchronized collections, immutable collections, and performance considerations, which are crucial for building high-performance applications.

• Learn how to effectively use Iterator vs ListIterator to handle data iteration more efficiently.

• Gain insights into concurrent collections, preparing you for modern, multi-threaded application development.

Module 5: Java 8 Enhancements to Collections & Stream API

• Learn how Java 8’s Stream API transforms data manipulation by simplifying your code with lambda expressions and parallel streams.

• Explore advanced operations like collectors, internal iteration, and functional programming in Java, allowing you to write cleaner and more efficient code.

• Boost your productivity by mastering the Stream API, which is widely used in modern Java applications.

Module 6: Concurrent Collections

• Master concurrent collections, a must-have skill for developing scalable, thread-safe applications that perform well under high load.

• Learn about key collections like ConcurrentHashMap, CopyOnWriteArrayList, and BlockingQueue, which will empower you to handle concurrency challenges in your projects.

• Gain practical knowledge to write multi-threaded code that works efficiently in a real-world environment.

Module 7: Algorithms and Utilities in Collections

• Learn essential algorithms like sorting, searching, and shifting to optimize data handling in your applications.

• Understand how to use utility methods for common tasks, which will save you time and effort when working with collections.

• Enhance your problem-solving skills by mastering useful operations like reversing, rotating, and filling, which are crucial for manipulating large data sets efficiently.

Module 8: Practical Examples and Use Cases

• Apply your knowledge with real-world projects such as managing a to-do list, implementing caching mechanisms, and task scheduling using collections.

• Develop practical skills that directly translate to job-ready expertise by working with collections to solve everyday software development challenges.

• Get valuable experience in building systems that handle real-world data management needs.

Module 9: Collection Framework in Interviews

• Prepare for technical interviews with a strong focus on Java collections. Understand common interview questions and practice real coding challenges to boost your confidence.

• Learn how to answer tricky interview questions like:

  • How does ConcurrentHashMap ensure thread-safety?

  • What’s the difference between HashMap and LinkedHashMap?

  • How does TreeMap handle sorting?

• Tackle HackerRank challenges to solidify your skills and prepare for interviews with confidence.
