Java Class Loader

A Java Class Loader is a component that dynamically finds and loads Java classes into the JVM at runtime. Think of it as a librarian that fetches and prepares books (classes) when needed. When a program runs, the Class Loader searches for class files in specified locations, loads their data into memory, and makes them available for use. This mechanism allows Java to load classes on demand, support modular applications, and update classes without restarting, improving flexibility and resource management during program execution.
