JVM and Java Internals

[Nancy Antony]

Hi Ranchers,

Where can I find Java internals and JVM architecture and Internals?

Regards,
Nancy

You can have a look at the book: Inside the JVM- http://www.artima.com/insidejvm/ed2/

This would better be in- Java General (or Beginners Java?) forum.

check out VM Spec.
also, you can find the source code and documentation of JVM here.

Agreed.

This question has been asked a lot here, it is better to part of the FAQ.

You can get the source code of the JVM at http://openjdk.java.net/ but it is ofcourse not a small or simple project.

Hi,
You can find in detail of JVM and JVM internals if you find the book Java virtual machine internal architecture if I'm not mistaken.
It is a really a good book for a beginner.

Java Virtual Machine (JVM) Introduction
A Java virtual machine (JVM), an implementation of the Java Virtual Machine Specification, interprets compiled Java binary code for a computer's processor so that it can perform a Java program's instructions. Java was designed to allow application programs to be built that could be run on any platform without having to be rewritten or recompiled by the programmer for each separate platform. A Java virtual machine makes this possible because it is aware of the specific instruction lengths and other particularities of the platform.
JVM becomes an instance of JRE at runtime of a java program. It is widely known as a runtime interpreter.

According to the link you posted, it describes the Java 1.2 virtual machine. The current JVM is very different, so you would have to regard that book as out of date and obsolete. It was even out of date 4 years ago when you posted.
