Collection Framework in Java

Introduction

This project showcases the extensive usage of the Java Collection Framework, which provides a unified architecture for representing and manipulating collections. It includes examples of various data structures such as lists, sets, and maps, along with advanced features like concurrent collections and custom implementations.

Features

• Detailed examples of List, Set, and Map implementations.
• Demonstrations of Java 8 Stream API, including intermediate and terminal operations, lazy evaluation, and parallel streams.
• Examples of concurrent collections such as ConcurrentHashMap, CopyOnWriteArrayList, ConcurrentLinkedQueue, and BlockingQueue.
• Custom implementations like an LRU Cache.
• Usage of specialized collections like IdentityHashMap, WeakHashMap, EnumMap, and ImmutableMap.
• Insights into Java features like garbage collection, hashCode and equals methods, and more.
