Hello and welcome to cc11rocks' tutorial on the easy way of installing
the JDK and JRE in Ubuntu.
I originally created this video in Windows a year and a half ago.
I am redoing this for Linux because this is now what I will be doing my tutorials on
I now have the ability to record in HD and my voice is no longer that of a 12
year old or thereabouts
if you want to install the JDK in Windows, go ahead and click on the following link.
You must have a plain text editor installed on your computer such as Gedit or Kate for Linux
or Notepad++
for Windows to program in Java or most other languages
all three of these programs are free and include syntax highlighting and other
helpful features.
For example, this is Gedit.
When you save it as either .java (file extension) or
it depends what your programming
It includes syntax highlighting, which i will show you later.
All three of these programs are free and include syntax highlighting and other helpful
features.
You can manually install Java yourself by going to the official Oracle site and downloading
it there,
but this is somewhat a pain in the butt, and you will manually have to upgrade when there are updates.
You have to set your environment variables yourself and do all kinds of
stuff that I've done before.
After having completed this process several times and eventually coming up with a
script for it,
I have found a PPA which is a personal package archieve to do this for me.
My personal favorite PPA team is webupd8 and I try to stick with them for my PPA's
because they are trusted and their PPA's work very well.
You can go ahead and run these commands
one-at-a-time
in order to install the JDK seven (7) and JRE
seven (7), which is the most
current JDK and JRE version.
Java seven (7)...
This video may be out of date when you watch it, it might be Java 8 or later
but this still
should work as long as they keep updating it, which they have so far.
So,
the first command adds the PPA to your repository.
The second command grabs the links for the latest packages
for your repositories, including the newly added one.
The last command installs the installer.
Webupd8 updates the
JDK version and is automaticly updated when a new version comes out.
The installer most likely grabs the packages from the official Oracle cite and installs them,
much like my homemade script;
except my homemade script was
kind of a piece of crap. It didn't work all the time and stuff changes
but webupd8 does all the stuff for you and you don't have to worry about
changing your environment variables
and all kinds of
trash that
the PPA can do for you.
[Correction] What the
program can do for you but you need the PPA for it because it's kind of a pain in the butt
if you don't use the PPA and there's no reason really not too.
To make sure that the JDK and JRE were properly installed after you run these
commands,
then you need to run some other ones.
Run "java -version"
and
this will tell you your Java version.
If you don't come up with an error, you should be okay. It should look something like will.
Of course,
this will look a little bit different because you probably won't be running the
same version.
And then javac...
The first one test to see if you have the JRE - which is the Java Runtime Environment -
which is required to run Java programs
and "javac -version" tests if you have
the JDK, which is Java Development Kit,
which is needed to develop
Java programs.
But,
three three commands right here will allow you to
install the JDK and JRE at the same time.
I hope you enjoyed this video.
Please like and favorite this video and subscribe to my video to make sure to catch my videos when they
pop up.
I'm currently producing videos when i have spare time on programming and
Linux and related tutorials and reviews.
Just a quick note : I'm starting to put
Youtube advertisements starting with this video. I personally hate the pop-up
ones at the bottom of the screen and so i won't enable those.
I'll only enable the ones at the start.
Thanks for all you guys' support.
I recently hit a new record, if you want to call it that, of over fifteen
thousand (15,000) total video views
and nineteen (19) subscribers
and so
I hope to create more.
Again, I don't really have a ton of time : I have work, school, and
I'm dealing with a lot of stuff right now but I should be making more in the
future
I really do hope you enjoyed it!
