Hey, what's up, John Sonmez from simpleprogrammer.com.
I've gotten this question a lot and I'm
finally going to give an answer here which

is: How do I learn Java?
What is the best way to learn Java?
How can I learn Java?
Please, sir and variations of that, basically
how do you learn Java, how can I learn Java?

I think that this is an interesting question
because it's—specifically some of you

are asking how to learn Java and I'll give
you some specific Java resources, but learning

a programming language in general is really
what you're trying to do.

That's the skill set.
The resource I'm going to give you for learning
programming is I've got a couple of blog

posts and I actually wrote book called The
Complete Software Developer's Career Guide

and I have some resources there where you
can learn how to learn a programming language.

Go ahead and check that out.
You can sign up to get free chapters of the

It's totally free if you sign up via email
and then you could buy the hard copy if you

want once it's complete.
I will talk specifically about Java, about
learning and I'll give you a few resources

Java is probably a good programming language
to learn.

There's a lot of resources out there.
It's a very popular programming language.
It's an object-oriented language.
It's fairly simple.
It's a lot less complicated than C++.
I did a video on how to learn C++ and I kind
of discourage you from learning C++ in that

video because I think that that's really
hard for a beginner.

I think C++ is a valuable language but it's
much more difficult.

With Java you don't have to deal with a
lot of that kind of problems.

Java is still a fairly complex language.
It's not a simple language so you've got
to have a good strategy for learning Java.

My primary strategy, I've actually taught
courses on Java and I'll link you to those

in a little bit here, but first I want to
talk about the strategy and what I thought

was most effective for teaching people Java
which is not to try and learn it in a vacuum.

What I mean by that is—and this probably
applies to most programming languages is that

it's a good idea to learn a programming
language with a technology, with some kind

of application that you're going to use
it with.

If you just try to learn Java in a vacuum
that means that you're trying to learn syntax

of Java and maybe you're trying to write
Command Line Programs to use the Java and

it's going to be hard because we don't
learn that way.

The reason—the whole purpose of learning
in general is to solve problems.

We have something that we want to do—and
anytime you're trying to learn something

you should always ask, “What do I want to

“I want to learn this so that I can do X.”
For Java it probably should be, “So I can
build an app” maybe it's, “So I can

build an Android app.”
Now that's a pretty good reason.
Maybe it's a web app if you're going to—but
that's going to—not only is this going

to give you a goal, not only is it going to
help you to stick with what you're learning,

to get that into your mind and to understand
it better, but it's going to give you specifics

of what you want to learn in Java, because
Java is a programming language.

It's a toolbox.
If you said, “I want to learn how to use
tools” that's kind of silly, but if you

said, “I want to learn how to build cabinets
and these are the tools I want to use to build

the cabinets” now you're getting somewhere
and that is the key.

That's how we're going to learn Java.
In the past what I have taught people to do
is to combine Android and Java at the same

It seems like this is 2 things to learn, and
it is, but it will give you some kind of application.

It doesn't have to be Android, but if you
pick something, maybe you want to build a

Java web app, good, great, a Java Android

A Java desktop app or whatever it is, pick
something that you're going to build and

that's going to be the driver.
From there you're going to work backwards
and say, “Well, what do I need to know in

order to be able to build that thing?”
That's how you're going to judge your
competency level.

You're not going—again, you're going
to learn the things, 80% that's critical

in order for you—or the 20% that's critical
in order for you to do 80% of what you need

to do.
You're not going to try to learn the whole
Java at one time.

There's a lot of stuff and you can be overwhelmed.
Here's where I'm going to give you some
links for some resources based on this.

I did a few PluralSight courses on this on
learning Java.

I did a 4-part course.
We'll try to get links here for all 4 of
these courses because they—unfortunately

on PluralSight's navigation it doesn't
really show them in order, but basically the

first course is on an introduction to Android.
It just talks about Android itself so you
have the basics of Android.

The next one talks about—is using the app
inventor, this is kind of a drag and drop

kind of programming interface like _____[inaudible
00:04:50] which you've seen.

That course showed you how to build basic
Android applications but you're using some

logic, right?
Then the third one, and you could start at
the third one if you want, it's called Just

Enough Java.
You can get that here.
What it does is it basically teaches you Java
as you're learning to build an Android application.

I say, “Okay, whoa, we need to build this

Now let's get introduced to this Java functionality
that will allow us to do this particular thing.

Oh we need to execute something here so now
let's talk about what a function is.”

You see what I'm saying?
Or, “We need to encapsulate some of this
logic so I guess we're going to probably

have to use a class here.”
What you're doing is you're learning from
practical application.

It's going to stick a lot better.
A lot of people that have gone through that
class have found that, “oh, I'm learning

Java much easier than before” because they're
learning it that way and it sticks.

You learn just enough Java to be able to get
an Android application built to get that application

The fourth one is actually the most fun.
I've got how to build a game, your first
PC game using Java.

I go through—that's a fun course.
I give all kinds of voices and animations
and all kinds of cool stuff.

I actually show you how to take what you learn
now and we're going to expand a little bit

more and learn more concepts in Java as we
build out an actual game.

We're using even a different platform at
that point.

You're learning Java by learning how to
actually utilize it which is really important.

I also have 2 other PluralSight courses on
learning Java that is more of the traditional

If you rather just—and you can use resources
and—but it's still built, it still builds

on building an application.
This is the key thing.
It's a little bit different this application
I believe in one of these courses is a printer,

kind of a virtual printer that we're creating.
You can check that out.
I believe it's called Introduction to Java
1 and then the second module in that course

or the second course in that is I believe
Introduction to Java 2.

You can check both of those out on PluralSight.
I've got a bunch of courses.
I've done 55 courses on there.
Anyway, I take that approach.
The approach that I just told you about how
to learn Java that's what I'm doing in

those courses and I'm showing you how to
actually apply what you're learning so you

can actually do something.
That's the key.
Again, if you want to learn any kind of programming
language or really anything you want to always

ask yourself this question of I want to learn
X so I can do Y. that is going to inform you

about what to learn and it's going to make
it so that it sticks in your head.

You understand the concept because you're
actually using it.

I could tell you about all the tools that
a woodworker uses, right?

I could explain to you how a lathe works and
how a drill works and all of these things.

You may be able to absorb some of that.
But if I go in and I say, “Look, you want
to learn how a lathe works?”

I don't even know what a lathe is.
Or a planer, I know what a planer is.
We need to smooth down this surface, so here
use the planer and plane it.

You see how this works?
This is why we're doing it.
We need to put a hole here.
Here's how this press drill works.
Or whatever it is.
I'm showing you how to do it.
You're actually using it to actually build
something, build a cabinet or whatever it

is and now you understand it, now it sticks.
Now it makes sense because it's not just
learning about some keyword in backing.

Do you understand what I'm saying?
So many people try to learn Java or learn
any kind of programming language the wrong

way and that's why they can't learn things.
It's a frustrating experience.
I couldn't learn like that.
You've got to be applying it.
I'll give you one other resource I think
that is a good one for a book.

This is not my book but it's called Head
First Java, actually I'll give you 2.

You can check that out here.
This is kind of a good one.
It's a different out of the box way of thinking
about how to learn a programming language.

I like that a lot.
Actually, I'll give you a few of them now
that I'm coming up with many ideas.

Another one is a book by Bruce Eckel that
was one of the first Java books I ever read

called Thinking in Java.
I think that's a good one.
It's a little bit dated but I think it's
still got good information there.

Then I'll give you another one, a really
large book if you large the thoroughness,

it's a beautiful book.
The Deitel books I just love them because
they're—they meet my OCD requirements

for packaging and how a book should look.
It's called Java How to Program.
It's by Paul and Harvey Deitel.
It's a real good one.
You can check those out.
There are some more advanced books I could
recommend if you're going from beginner

to intermediate and that's a whole different

If you're interested, let me know.
I can do another video on that topic.
Key thing, again, you can check out my PluralSight
courses but however you learn Java, however

you learn any programming language the key,
key thing here is that you remember you've

got to apply this.
You've got to do it again.
Think about what I said about a woodworker
and a lathe or a planer because I don't

know what lathe is.
I think it's like a hook—I don't know.
Anyway, I hope that helps you.
If you've got a question about programming
languages or career or life, whatever, whatever
