Java Virtual Machine consists of the following Components:
1. Class Loader
2. Byte Code verifier
3. Interpreter
4. Just In Time Complier
5. Security Manager
6.Garbage Collector
Class Loader loads the .class file and this file is verified by Byte code verifier, if the byte code is tampered a message will be displayed. Else the Interpreter interprets and byte code and translates it into machine language. Garabage collector will regularly check for unreferrenced variables and frees the memory.
