So far, we've done all of our
learning in work spaces and
0:09
run all of our programs by typing
commands into the console.
0:13
These days instead of using the console
most programming is done using
0:17
an integrated development environment,
or IDE.
0:22
You can think of an IDE as basically
the Microsoft Word of writing code.
0:25
It underlines misspellings, highlights
errors, and even has auto-complete.
0:30
But most of all it just makes
programming a lot easier.
0:35
One popular IDE for Java is IntelliJ IDEA,
0:40
which we'll be using in this course and
you should start using going forward.
0:44
If you don't already have it,
take a minute to download it.
0:48
There is a link below
in the teacher's notes.
0:51
Once you've got IntelliJ,
there's just a few steps to set it up.
0:54
Let's pick Do not import settings,
then hit OK.
0:58
Then let's go to the bottom, and click
Accept to agree to the Privacy Policy.
1:02
Then on the Data Sharing screen,
1:09
you can either send them your usage
statistics or you can not send them.
1:11
I'll choose to send them.
1:16
Finally, we need to pick a theme.
1:18
I'll pick the light theme, but you
are free to choose whatever you'd like.
1:20
Then let's click Skip Remaining and
Set Defaults.
1:24
Nice, we are all setup and
ready to create our first project.
1:27
Let's get started with
the Create New Project button,
1:31
which helps us configure a project.
1:35
On the first screen we need to pick
which type of project we are making.
1:37
It's already set to Java, which is good.
1:41
But it looks like we're missing an SDK,
which is not so good.
1:44
SDK stands for
Software Development Kit, and
1:49
it's a set of files that defines
what something is and how it works.
1:53
In our Microsoft Word example,
an SDK will be kind of like a dictionary.
1:58
It defines what words are allowed and
2:02
tells us how those words can
be combined to make sentences.
2:05
In the Java world, instead of an SDK,
2:09
we have the JDK, or Java Development Kit.
2:12
And luckily, IntelliJ is nice
enough to include a download link.
2:16
Let's click that, and
then on the web page,
2:21
click the Download button at the top.
2:23
Then, click Accept License Agreement and
download the JDK for
2:29
your operating system.
2:34
So for me, I'll pick Mac OS.
2:36
Once the JDK is downloaded,
you'll need to install it.
2:41
I'll double click on the icon.
2:47
Which brings me to the installer,
2:52
click Continue, pick Install.
2:56
Now I'll need to put
in the admin password.
3:00
And now we've got the JDK.
3:07
Now that we've got the JDK, we just
need to tell IntelliJ where to find it.
3:10
Alternatively, we can just hit Cancel and
3:14
then Create a New Project, and
IntelliJ will find it for us.
3:19
Let's click Next, And
3:24
then choose to create the project
using the Command Line App template.
3:28
This template gives us a simple Java
application with a main method,
3:33
just like we're used to.
3:37
Let's hit Next again, and
then give our project a name.
3:38
Let's go with MyFirstProject and
move onto the Project location.
3:43
This is where the project will
be stored on your computer.
3:50
By default all projects will be
stored inside of a folder named after
3:53
the project.
3:58
And that folder will be stored
in the IdeaProjects folder.
3:59
Though you can change where a project is
stored, by either typing a new location,
4:03
or clicking the three dots on the right.
4:07
The last thing we need to do,
is set the package name.
4:12
Typically, this would be
the reverse of your company's URL.
4:15
So for me,
that would be com.teamtreehouse.
4:19
Though the package name isn't super
important unless you plan on publishing
4:25
your app.
4:29
So for now let's all just use the same
package name com.teamtreehouse.
4:31
Finally, let's click finish and
IntelliJ will create the project.
4:37
And if the directory doesn't exist,
it'll create that too.
4:41
In the next video, we'll see what
was created and run our new project.
