JVM Java Virtual Machine Architecture and Structure
- JVM is responsible for taking .class file and converting that .class file in machine code instructions that can be executed by microprocessor.
- It’s not a machine, it’s a program.
- JVM verifies the code before execution (Sandbox Security).
- JVM is platform dependent and it is heart of Java language.
There are four phases of JVM
- Load Code
- Verify Code
- Execute Code
- Provide Runtime Environment
