 Java virtual machine - Wikipedia, the free encyclopedia
A Java Virtual Machine (JVM), originally developed by Sun Microsystems, is a virtual machine that executes Java bytecode.
This binary is then executed by the JVM runtime which carries out emulation of the JVM instruction set by interpreting it or by applying a just-in-time compiler (JIT) such as Sun's HotSpot.
These JVMs interpret the byte code semantically the same way, but the actual implementation may be different.

 Java Virtual Machine Profiler Interface
The Java virtual machine is a multithreaded and garbage-collected execution environment that generates various events of interest for the profiler.
The Java virtual machine is a multithreaded execution environment.
A straightforward solution is to require the virtual machine to record all profiling events in a trace file, whether or not these events are enabled by the profiler agent.

 Alternative Java Implementations
The JVM can be implemented on real computers in many different ways, and that's the point: as long as your computer faithfully recreates this abstract computer, it can run programs stored in class files.
The JVM is an abstract computer that executes programs stored in "class" files.
The Java language is an object oriented computer programming language that resembles C++ and Objective-C in syntax, with its semantics being more like a cross between Ada (for typesafety) and Smalltalk.

 Java Programming: Section 1.3
There is no reason why Java bytecode could not be used as the machine language of a real computer, rather than a virtual computer.
Programs written in Java are compiled into machine language, but it is a machine language for a computer that doesn't really exist.
Virtual PC is an interpreter that executes machine-language programs written for IBM-PC-clone computers.

 Java Virtual Machine
Java problems for the average computer users started when Sun sued Micro$oft over their java virtual machine.
If you do encounter one of the rather rare web sites with java that was written to work with Sun java and not virtual machine, you can get the latest version from Sun here That is if you really want to see it.
New and average users should NOT "get Sun java" because there are too many places where it just does not work, and a multitude of places where it might work for advanced users but the average newbie will not know what to do.

 Java Virtual Machine
Since many of the Java VM instructions refer to data entities retrieved from a class file, understanding the contents of a Java class file is essential.
However the Java specification does not include a text format for Java class files (it only describes the underlying binary byte format of Java class files).
On the other hand, there are new classes in the java.* packages in 1.1, and some new attributes have been added to class files to support new features such as RMI and inner classes.

The Java architecture is very open -- it's easy to add programmatic extensions to Java, once you have used this book to learn the basic rules of the Java Virtual Machine.
Perhaps the most important reason for learning about the Java Virtual Machine is that it gives you additional tools for solving programming problems in Java.
The book is divided into three sections: the first section includes overview of the machine, information on the semantics and structure of the JVM.

 The Java Virtual Machine Specification
In The Java Virtual Machine Specification, Second Edition, Sun's designers of the Java virtual machine provide comprehensive coverage of the Java virtual machine class file format and instruction set.
In all, the book provides sufficient detail to enable you to implement your own fully-compatible Java virtual machine, or on the other hand, to just really understand what makes the Java technology work.
In addition, the book contains directions for compiling the virtual machine with numerous practical examples to clarify how it operates in practice.

 Inside the Java Virtual Machine
Inside the Java Virtual Machine describes the Java virtual machine, the abstract computer on which all Java programs run, and several Java APIs closely related to the virtual machine.
Eleven of the applets simulate the Java virtual machine executing bytecodes.
Similarly, Chapters 10 through 20 form a tutorial of the Java virtual machine's instruction set, and Appendices A through C serve as a complete reference of the instruction set.

 ERCB: Java Virtual Machine Specification
The body of the book is devoted to the Java virtual machine opcodes, which are discussed one at a time with their binary representations, stack effects, side effects, exception conditions, and miscellaneous programming notes.
Forth is based on a virtual machine architecture not terribly dissimiliar to Java, but I don't think I could program my way directly to a working JVM that would run any ol' Java applet I found on the Internet, using just the information supplied here.
Here at ERCB, we've received at least a dozen shelf-feet of Java books for review from various publishers, but on close inspection many of them are merely warmed over C/C++ programming books by the usual stable of C/C++ programmer-authors.

 Ghost Machine
Implementing a Java virtual machine for these devices provides a better way of developing and distributing software.
Off-loading virtual machine activity onto a server like machine allows Java byte code to run effectively on these devices.
Other platforms should work, however, since the server is written in pure Java using standard APIs and no graphical user interface.

 Amazon.com: Inside The Java Virtual Machine: Books: Bill Venners
This title provides a remarkably detailed tour of the internals of the Java platform, with plenty of technical information on the way virtual machines do business under the hood, from the way language statements are turned into bytecodes to in-depth coverage of loading and invoking classes, security, and garbage collection.
I found its reference section to be slightly less intuitively-organized than the JVM spec, and the rest of the book didn't really add a lot of new insight, beyond a semi-guided tour of the Java Class File format.
This book is mostly a rehashing of the Java Virtual Machine Specification (which is available online from Sun, or in printed form).
