There are many places that claim to be trustworthy downloads for the Java Virtual Machine, but most of those sites can be a very big risk to the safety of one's computer. The most trustworthy vendor of the Java Virtual Machine is the Java website which also offers downloads to the latest updated versions of the JDK and other Java products.
You must have the Java Run-time Environment installed on your computer. Steps: 1. Open Command Prompt 2. Enter the command: javac class.java 3. Enter the command: java <classfilename> (without the .java or .class extension) The javac command will compile your java source file and create a class file. The java command will execute or run your java class file.
JRE stands for Java Runtime Environment. JRE is the runtime set up that is required by the JVM to execute java programs. The JRE and JVM (Java Virtual Machine) come packaged along with the Java Development Kit (JDK) that we download and install from the suns website to install Java.

Modern machines do not consist of multiple levels of virtual machines; that is a function of the host operating system's virtual machine manager and its guest operating systems, all of which are implemented through software. The operating system's virtual machine manager exposes one or more virtual machines upon which you can host one or more guest operating systems and their applications. In order to execute compiled Java applications upon one of these guest operating systems you will also need to install the Java virtual machine for that specific operating system. Thus you end up with a Java program executing within a Java virtual machine executing within a virtual machine executing within a virtual machine manager executing upon the physical hardware. The physical hardware itself may be optimised to handle virtual machine managers more efficiently, but the virtual machine manager is a software program; it is not part of the physical machine architecture

One could find more information about the Java Virtual Machine online on various websites such as 'Wikipedia', 'Java-Virtual-Machine' and of course the website 'Java'.

Java virtual machine
Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine. The Java platform is usually associated with the Java virtual machine and the Java core libraries.
1.Java virtual machine is required to interpret .class files. 2.JVM makes the java as platform independent.
While there are several implementation of the JVM, you can find the one from Sun at http://java.sun.com/javase/downloads/index.jsp
The Java platform, which consists 3 major parts: Java programming language, Java Virtual Machine (JVM), and several Java Application Programming Interfaces (APIs), was developed at Sun Microsystems in the early 1990s.
You will no longer be able to run Java programs.
Java byte code is the code that is output by the Java compiler. Byte code is not machine code, it must be interpreted to create the machine code. This is handled by the Java virtual machine. Pretty much every platform produced today has a Java virtual machine implementation, so the same byte code can be executed upon any machine. Byte code can be regarded as being the native language of the virtual machine, as opposed to machine code which is the native language of the physical machine.
A Java Virtual Machine enables a set of computer software programs and data structures to use a virtual machine model for the execution of other computer programs and scripts. The model used by a JVM accepts a form of computer intermediate language commonly referred to as Java bytecode. A virtual machine is a software implementation of a machine (i.e. a computer) that executes instructions (not programs) like a physical machine.
yes its a programing tool.
