Core Java

Key Areas of Core Java: Object-Oriented Programming (OOP): Uses concepts like classes, objects, inheritance, polymorphism, encapsulation, and abstraction. Java Standard Edition (Java SE): Includes libraries for data types, networking, file handling, multithreading, collections, exception handling, etc. Platform Independence: “Write Once, Run Anywhere” (WORA) – Java code compiles to bytecode that can run on any system with a JVM. Memory Management: Uses automatic garbage collection, reducing the chances of memory leaks. Multithreading: Supports execution of multiple threads simultaneously. Security: Built-in security features like the Java Security Manager and automatic checks during runtime. Core Java Use Cases: Desktop Applications Basic Web Applications Utility Tools Data Processing Tools Android App Development (as a base language)
