Java Virtual Machine
Java Virtual Machine
Provides hardware platform specifications
Reads compiled byte codes that are platform independent
Is implemented as software or hardware
Is implemented in a Java technology development tool or a Web browser
JVM provides definitions for the:
- Instruction set (central processing unit [CPU])
- Register set
- Class file format
- Stack
- Garbage-collected heap
- Memory area
Bytecodes that maintain proper type discipline from the code.
The majority of type checking is done when the code is compiled.
Every Sun approved implementation of the JVM must be able to run any compliant class file.
