A Java virtual machine (JVM) is an abstract computing machine that enables a computer to run a Java program. There are three notions of the JVM: specification, implementation, and instance. The specification is a document that formally describes what is required of a JVM implementation. Having a single specification ensures all implementations are interoperable. A JVM implementation is a computer program that meets the requirements of the JVM specification. An instance of a JVM is an implementation running in a process that executes a computer program compiled into Java bytecode.
Java Runtime Environment (JRE) is a software package that contains what is required to run a Java program. It includes a Java Virtual Machine implementation together with an implementation of the Java Class Library. The Oracle Corporation, which owns the Java trademark, distributes a Java Runtime environment with their Java Virtual Machine called HotSpot.
Java Development Kit (JDK) is a superset of a JRE and contains tools for Java programmers, e.g. a javac compiler. Java Development Kit is provided free of charge either by Oracle Corporation directly, or by the OpenJDK open source project, which is governed by Oracle.
http://www.guru99.com/java-virtual-machine-jvm.html This tutorial first explains the compiling process in C language , then compares the same in Java in the process explains the working of Java Virtual Machine - JVM. It also explains JVM architecture.
In this video I tried to explore one of the popular core Java interview topics - Java virtual machine architecture - this provides you a fairly detailed walk through, also touches up on topics such as permgen and metaspace( jdk8) - I am going to post more topics like these, hit subscribe if you like what you see.

In this video, Dr. Ian Rogers of Azul Systems is going to cover in detail what a Java Virtual Machine (JVM) is and what it does for your Java applications. Ian will dive into the inner workings of the JVM and drill down into what compilers and garbage collectors do. In particular, you will learn about common optimizations, well established garbage collection algorithms, and what the current biggest challenge with Java scalability is today. ** Find more educational content on Java development at http://marakana.com
JVM ( Java Virtual Machine) Architecture Simple Explanation www.twitter.com/cyberaditya www.facebook.com/cyberaditya
the things which we ignore the most often become the most important . Here's a basic understanding on the Difference between JDK, JRE and JVM.
We explain what compilers, interpreters, and the Java Virtual Machine (JVM) are. The playlist with all my Java videos is http://www.youtube.com/playlist?list=PLF03C6B2C0B292A1E This video is for beginners. It is a super-simplified explanation. To learn more of the details, I recommend taking MIT's 6.004 at http://ocw.mit.edu
Sverige vinner Junior-VM igen efter 31 års väntan. Höjdpunkter från matchen.
I'm a slow typer, a so-so writer
Been the shit ever since I was an infant in diapers
And Imma be dope all the way to the end
From the cradle to the grave, the pampers to the depends
Get enough love, got enough friends
But on a regular basis, it's safe to say I got the bends
And I didn't mean to ignore that vibe you sent
I guess my mind was probably on my rent
I got my mind on my tummy and my tummy on my mind
Some assembly required, let me run it down the line
The factory is open, time card punched
Until lunchtime, it's crunch time
Back to work fool.
First rule is to keep the verse true, even if it hurts you
You gotta wear the pain like a stain
Respect the listener, respect the game
Because there's more to gain than just some dinner and fame
Gimme the money, but don't you dare stop there
Gimme the mic, that's the tool, and I play it cool
Gimme the life, I seen things that used to be dreams
Gimme the love, my name's Slug, gimme a pound or a hug
And I'mma play this game
I just wanna say all I really want is for you to remember my name
And Imma run for as long as I'm allowed
Hope to god I inspire some of yall
See I'm that cat that used to sit in the back and study
Looking for some proof that god loves ugly
Flash forward a decade later in your town
Somehow a good number of yall got down
And it's solid, fresh, dope, whatever you wanna call it
Not bad for an aspiring sociopathic alcoholic
Aw shit, look at Slug, still rockin the same outfit
Tryin' to make the belly grow bigger than the wallet
Hey yo man, how you doin, how you been
Just makin it cool to rap about love again
Not the hippie stuff, I'm talkin bout that bitch that gets you nuts
(Did he say bitch?) Yo I'm sorry, don't tell my baby's mommy
Speakin of baby,
There'll be a crateful of albums for my son to page through
Thinkin daddy was a gun
With a handful of heads that put me up til they had some samples from
Ant and fake them what the fuck I said
Still goin, still maintainin, still standin in the land of snow and purple
Rain
And I'm still waitin for my date to kiss me or slap me
Cause there ain't no way that I can be happy when I'm happy
Gimme the money, but don't you dare stop there
Gimme the mic, that's the tool, and I play it cool
Gimme the life, I've seen things that used to be dreams
Gimme the love, my name's Slug, gimme a pound or a hug
And I'mma play this game
I just wanna say all I really want is for you to remember my name
And Imma run for as long as I'm allowed
Hope to god I inspire some of yall
I've had the pleasure of speaking with some of you (yeah you)
Come on now, don't act like you don't know who I'm talkin to
After that show, when you approached me like you know me
The cd I sold you, the secrets that you told me
On that world you vision, through the layers of tears
The ones you choke and keep hidden when the players are near
I watch you chase it with beers and frustration and fear
Try to figure out why the hell I came here
Well I don't know either, and I'm not ready to take a breather neither
All I know is I'm still a believer
So you can beat me up, or you can beat me off
Pick a side, any side, and let me do my job
If you've got a lot of love to give, but you don't know who to give it to
Imma turn out the lights and light this cigarette
And write a song about you (this one's for you)
Gimme the money, but don't you dare stop there
Gimme the mic, that's the tool, and I play it cool
Gimme the life, I've seen things that used to be dreams
Gimme the love, my name's Slug, gimme a pound or a hug
And I'mma play this game
I just wanna say all I really want is for you to remember my name
And Imma run for as long as I'm allowed
Hope to god I inspire some of yall
Please god (but don't you dare stop there)
That's the tool and I play it cool
I've seen things that used to be dreams
