Now on Java tutorial we begin with the section 2 that is about JVM – Java Virtual Machine. And also about the difference between JDK Vs JRE Vs JVM including other aspects of Java Virtual Machine.

The virtual machine or processor inside your computer that provides an environment for all the Java programs to run on your computer is the Java Virtual Machine. It is a set of specifications of an abstract machine that loads the file containing the programming, interprets it and also helps it being executed it. Java software for your computer, or the Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on or Java download.

Having an Intel CPU is the easiest way to run a Mac OS X virtual machine. That is because Mac computers and laptops use Intel CPUs exclusively, and therefore the virtualization is straightforward, from a technical point of view. Download the macOS High Sierra image. So, we have to download the Intel version of the Mac OS X virtual machine. Download Java Virtual Machine Mac Software Advertisement JC virtual machine v.1.4.7 JC is a Java virtual machine implementation that converts class files into C source files using the Soot Java bytecode analysis framework, compiles them with GCC, and loads them using a built-in ELF object loader.

Guys, to deep dive in java, let’s have a look how it works internally.


A role of Java virtual machine (short form as JVM) is to execute Java bytecode. We can state that JVM is the component of the Java software platform where code execution happens. Right now over 5.5 billion computer are in the market which are JVM-enabled. JVM lives inside our PC/computer and byte code is the language for JVM. With the introduction of JVM, job of compiler becomes very easy as it only generate byte code for JVM rather than generating different machine code for each m/c which is the reason why java language is platform independent.

A JVM executes programs containing Java bytecode instructions and are generally implemented to run on existing operating system (windows etc). A JVM provides a run-time environment which enables features such as exception handling which in turns provides debugging capability for every software exception. A JVM is a part of Java Class Library (some inbuilt java classes in the form of bytecode) to provide basic functions to developer while doing coding in Java. These libraries with the JVM together named as Java Runtime Environment (JRE).

JVMs are compatible and available for almost all hardware and software platforms. Due to this feature of using the same bytecode for all JVMs on all platforms makes Java to be known as a write once and run anywhere language. This clearly describe that JVM is a crucial component of the Java language. Java bytecode is an machine language which is typically compiled from Java (or from other programming languages).

HotSpot is the most used JVM which is written in the C++ programming language. JVM doesn’t understand Java code due to which we require java compiler that compiles source code and create .class file. This .class file is composed of byte code which JVM can understand. There are two main components of JVM – heap memory and garbage collector. We will discuss about both in detail in the upcoming discussion.

How JVM works

Now moving on with the Java tutorial section , we will see working of Java Virtual machine ie, how JVM works exactly.

Look at the pictorial format that explains the working of JVM.

  • After reading .class file, class loader save the corresponding byte code in the method area. Generally all JVMs have only one method area which is shared across classes which holds information related to each .class file.
  • Heap is an integral part of JVM memory in which the objects actually rests. JVM produces the Class object for each .class file.
  • Unlike Heap, Stack is used for storing temporary variables.
  • PC-Registers used to keep exact information of all instructions (which instruction is executing and which is going to be executed).
  • A native method used to access the runtime data of the JVM (java virtual machine). Native Method interface enables java code to call by the native applications (programs that are specific to the hardware and OS).
  • We will cover Garbage collection in the upcoming article

JVM Vs JRE Vs JDK

Now let’s sort out the difference between JVM ,JRE and JDK . How does these differ from each other – JVM Vs JRE Vs JDK .

JRE ( Java Runtime Environment )

Java Runtime Environment is within which the java virtual machine actually runs. JRE contains Java virtual Machine and other files except development tools (debugger and compiler). So developer can run the source code in JRE but he/she cannot develop and compile the code.

JVM ( Java Virtual Machine )

As per above discussion, JVM runs the program by using libraries and files provided by Java Runtime Environment.

JDK ( Java Development Kit )

Java Development Kit can be considered as the super-set of JRE. JDK includes all features that JRE has and over and above it contains development tools such like compiler, debugger etc.

Now we have discussed about what is JVM ( Java Virtual Machine ) and how JVM works . Also in depth we have discussed about the difference between JVM Vs JRE Vs JDK.

Java Virtual Machine Mac Install

On the third session of Java Programming Tutorials we will discuss about the Java Basic Syntax and Java Environment Setup .

Microsoft Virtual Machine

The Microsoft Java Virtual Machine is no longer available from Microsoft directly due to legal wrangling with SUN, however it still can be downloaded..

Microsoft VM build 3810 for Windows Vista, Windows XP, Windows 2000, Windows 95/98, Windows Me, Windows NT 4.0. 5.07 MB

Microsoft Java Virtual Machine download links:

Steps to install the Microsoft Virtual Machine:

  1. Download the file using the links above and save it to your harddrive.
  2. Once the file is on your harddrive, execute it and thus load the Virtual Machine.
  3. As the file begins execution, answer Yes to the License Agreement question and then once complete, re-boot your PC.
  4. Once the PC is re-booted you should be set to go.

One way to get Microsoft Java Virtual Machine

First go to this site and get the older version of the MS Java Virtual Machine:

This will check for the basic VM and install an older version onto Vista/XP, and then you need to go to Microsoft and install the Java 4.0 SDK which will give you the newer base java components. You can get those from this link: Microsoft SDK for Java 4.0 for Windows 95/98, Windows Me, Windows NT 4.0, Windows 2000, Windows XP, and Windows Vista or later:

FeaturesEasy to get started.Thonny comes with Python 3.7 built in, so just one simple installer is needed and you're ready to learn programming. Downloading python for mac

Java Runtime Environment 1.8

Once you have this installed and have re-booted your machine, then you need to go to the MS update site and install all the updates you do not currently have. The link to MS' site is:

When the updates are complete, you will need to re-boot one more time. After re-booting you will have the most current available Java for XP/Vista.

Sun Java Virtual Machine (JVM)

Microsoft had to take down their virtual machine because of some legal issues. But you don't even have to use the Microsoft VM, you can use Sun Microsystem's version, and it seems to work just fine.

Automatic Download and Installation (for Windows Vista, XP, Me, NT, 2000, or 98 and Internet Explorer)

Click to begin: Java Virtual Machine Download Page

First, our system will check to see if automatic install works on your computer..

  • If so, the automatic process previewed here will begin.
  • If not, you will see how to manually download and install,
    which is nearly as quick and easy as automatic installation.
