Java Architecture: JDK, JRE, JVM

• JDK (Java Development Kit):
  Full development kit including compiler (javac), libraries, and tools.

• JRE (Java Runtime Environment):
  Includes JVM and core libraries to run Java applications but no development tools.

• JVM (Java Virtual Machine):
  Executes Java bytecode on a given platform providing portability.

Interaction:

Developers write code → JDK compiles code → JVM runs compiled bytecode with JRE supporting runtime.
