Architecture
About
The Java Virtual Machine (JVM) follows a well-structured architecture that enables Java programs to be executed efficiently. It consists of various interconnected components, each responsible for handling different aspects of execution, memory management, and performance optimization.

Component
Description
ClassLoader
Loads Java bytecode into memory dynamically.
Method Area
Stores class metadata, constants, and static variables.
Heap
Stores all Java objects and instance variables.
Stack
Stores method execution frames and local variables.
PC Register
Stores the address of the next instruction.
Native Method Stack
Stores native method calls executed by JNI.
Interpreter
Reads and executes bytecode line-by-line.
JIT Compiler
Converts bytecode into optimized native machine code.
Garbage Collector
Reclaims unused memory automatically.
JNI (Java Native Interface)
Connects JVM with native code (C/C++).
