Please help me understand two things about JVM:
1. Is JVM partly software and partly hardware?
2. Is JVM platform independent?
Where can I find more info about JVM.
Thanks in advance

JVM is just a software. Java as a language is platform independant but as JVM are platform oriented. There are different JVMs available for different platforms.

In addition, Sun just publishes the specs for the JVM. Each browser vendor writes their OWN JVM, so they each act a bit differently. Sun did write the JVM in the JRE (Java runtime environment) which you would use if you have an application that does not run in a browser.

We should make a non-virtual java machine...one that objects to everything.
