Java Miscellaneous Class

🧑‍🏫 Java Miscellaneous Class – Detailed Overview

The Java Miscellaneous class is a combined session focusing on key advanced and practical topics that are often used across real-world Java applications. The class begins with Java programming practices, covering logic-building exercises like number patterns, recursion, and common algorithm problems to boost coding skills. Next, we dive into String handling in Java, where students learn about the immutability of String, and how StringBuilder and StringBuffer offer efficient alternatives in different scenarios. We explore internal memory behavior, string pooling, and manipulation techniques with hands-on coding.

The session then covers Garbage Collection (GC) in Java—how memory is managed, what the JVM does during GC, and how developers can optimize application memory usage using GC tuning and best practices.

Finally, we introduce essential Design Patterns like Singleton, Factory, and Strategy with examples, helping students write reusable, maintainable, and clean code.
