Java Programming Tutorial - 1 - Installing the JDK Video Lecture - Java

what's going on everybody it's Bucky and
welcome to your very first java tutorial
now in this tutorial before we begin
writing any programs we first need to
download something called the JDK and
for all you new Java developers out
there this is the program that lets you
actually write Java and actually compile
it and compile it just means
transferring it from code you can
understand the code the computer can
understand so just follow me by the end
you'll be able to write Java code so the
first thing I need you to do is go ahead
and open up your internet browser right
here and once you have that open I'm
going to use fire fact Firefox go ahead
and go to the website Java dot sun.com
and this is gonna give you a give you
Javas main page what you want to look
for is the download link and this is
gonna give you a bunch of different Java
editions to download you're gonna want
to go to the Java SE link and this
stands for a Java standard edition so go
ahead and click that and what we're
looking for is something called the JDK
in this stands for Java development kit
so we can write in a well compiled Java
programs now we just want the top one
which is a standard one on this EE
stands for Enterprise Edition this and
that beans is something else we don't
want that so just go ahead and find the
standard basic Edition and click
download and once you click that it's
probably gonna bring its a new page
let's see and you know and it's gonna
say Windows which we want English which
we want go ahead and agree and press
continue I already have this downloaded
so I'm not going to download it again
just be stupid but once you download it
it's gonna give you an executable file
now your executable file is gonna look
something like one of these this is
something else I downloaded but it's
going to give you a file like this
called exe once you get that file go
ahead and double click this and that's
going to start the wizard
download the JDK now it also might give
you a file on your desktop right here
like put it somewhere right here if it's
right there and just double click that
and once you do a Wizards gonna pop up
and you're probably gonna have to click
like next 40 times and press I agree I
agree to some stuff next next but once
that's all done then you're gonna have
the Java compiler downloaded now let me
show you guys what the Java compiler is
if you go to your Start menu then press
CMD and press Enter
your command prompt is going to come up
now what this allows you to do is have
access to your java compiler and again
like I said before deduct the Java
compiler allows you to transfer code
that you can understand to code the
computer can understand and that's what
we just downloaded so let's test it out
Java C press Enter nothing's working and
nothing's working because the Java
compiler it has it downloaded but
whenever you try to use it it doesn't
know where it is so let me show you guys
how to do that and again pay very close
attention to this hopefully you
downloaded it with all the default
settings um if you didn't then while
you're still going to be able to see
what's going on but go ahead and in your
Start menu click on computer now go
ahead and click the local disk witch or
whatever your main hard drive is then go
ahead and click program files now you
should have a folder called Java go
ahead and click that now go ahead and
click the version JDK if you don't see
this that means you didn't download it
right so go ahead and click that JDK the
next thing in last thing I want you guys
to do is click on the thing that says
bin right here and remember you follow
all these instructions very carefully
next right-click on any of these things
right here just click on your table
almost run remember right click it and
click properties now this is where
you're going to tell Java to look for
your compiler so it says location go
ahead and copy all of location right
clicking
be it it should say something like C
program files Java your version and Saeb
in the last thing make sure you get that
bin that's very important if you're not
if you don't see it then do this
tutorial again and do exactly as I say
anyways you want to see that bin so once
you have this golden code that's what
we're looking for go ahead and annex out
of that now that's where you the
compiler is so how do we tell your
computer to look there well go ahead and
go ahead to click on my computer again
from your Start menu and click
properties remember you want to right
click it and click properties all these
are very important go ahead and click
advanced system settings and probably a
little message is going to pop up if my
computer is not freezing and it is so my
computer properties advanced system
settings there we go continue and you're
gonna see something in your system
properties called environment variables
go ahead and click that and pay
attention what I'm gonna do here what we
want to do is create a new user variable
so go ahead and click a new now the
variable name for this you have to write
pass PA th and the variable value is
gonna right where that compiler is
remember that link with a bin so that's
why it's really important that you get
that link now go ahead and click OK
and bam click OK on this ok and you now
have your compiler set up and ready to
run so go ahead and go back to your
command line and in command line go
ahead and type Java sea and unlike
before we now have a bunch of crap that
pops up and this crap means that our
compiler is ready and set and ready to
go so now with that being said we know
that we are now able to write Java
programs so in the next tutorial I'll
show you guys how to do that but for now
just follow this tutorial that's how you
install Java on your
computer so you can actually write Java
programs if you didn't follow those
instructions exactly like I said
you're not going to be able to write
Java programs on your computer so make
sure follow this tutorial very carefully
do exactly as I did I know it's kind of
a pain in the butt but it'll be worth it
in the long run so um thank you guys for
watching make sure you get a job in salt
if you have any questions or I wasn't
clear on anything just send me a message
or leave a comment and hopefully I'll
get back to you so again thank you guys
for watching hopefully you have Java
installed and in next tutorial I'll show
you guys how to write our first Java
program so thank you don't forget to
subscribe to my channel and I'll see you
in the next tutorial
