Learn Java in 15 Minutes (seriously)

Out of pure spite, I've decided to make the world's shortest Java course to make it simple and straightforward for anyone to learn Java. Because according to a comment on my last video, "...anyone who use java can't really be taken seriously or professionally at this point. It's a dead language as far as current business standards go." I guess that commenter didn't realize 90% of Fortune 500 companies use Java.

Yea, instead of the ~5 minutes I removed from this video, I made it into an entire Java OOP crash course.

So here it is, a course for a programming language that'll actually get you a job.

0:00 Why, because haters
1:30 Java, because awesome
2:13 IDE, because easy
3:47 Make New Project, because duh
4:38 Hello World, because tradition
5:28 Data Types, because fundamentals
8:27 Arithmetic, because math
9:15 Methods, because reusable
12:10 Classes, because OOP
14:02 Control Flow Statements, because decision
17:41 Not World's Shortest Java Course, because talk a lot
18:19 Brilliant, because sponsor

Why waste time say lot word when few word do trick?

Don't know why you'd want to follow me on other socials. I don't even post. But here you go.

For you JS and python folks out there - The world runs on Java, C++, C and C#, and most of the web still runs on PHP. Whether you like it or not. C++ was the first language I ever learned 20 years ago now, and is still my personal favorite.

As a fortune 25 employee, JAVA is VERY MUCH USED AND IN DEMAND

[bradleytaylor]

I code in many languages, started in C++, continued in Java, then onto javascript, php, python, kotlin. Just keep learning, everything has a place and the more you know the more effective you can be in many scenarios.

I used java to get into programming, it's my first programming language and it taught me oop and I easily learnt other languages

[johnmuraski]

Side note - I personally think that Java or C++ should be the first languages young programmers learn. It forces to learn a lot of things that are far too easy to take for granted.

Your video reminds me of my son's journey in coding—he started with basic concepts but found his stride through hands-on learning at Moonpreneur. It's incredible how structured programs like theirs turn seemingly daunting languages like Java into approachable skills. This 15-minute guide is a great starter for anyone wanting to dive into the coding world—thanks for sharing!

Java the GOAT (semi joking, but I do love it) I think its overall the best general language and my hot take is that its actually good for beginners to learn because despite the verboseness, it forces you to think about your code and your data. And it does alot of things out of the box, its pretty darn fast and has many use cases. IMO theres a reason its an OG and still around killing it. Love Java!

everything is a tool. Go, Python, JS, C++, they are all tools. Pick the right tool for the job.

Thank you!! Please more of somewhat beginner content, I love how you explained it and also that you kept everything short as I feel that beginner courses are often too drawn out.

[shamylaa]

hi, new java programmer here (new to programming), this was pretty much useful and straight forward. I'm doing a computer science course in university and struggled with understanding the basics however your explanations really helped me understand it. I will watch your OOP video next and hope to learn more. Thank you:)

This is clutch. About to start CS2 in Java for fall semester 🙌🏼

[RajKumar-oypt]

You made me feel confident about learning Java. Thanks a lot! As a JavaScript developer, I was afraid of Java concepts, but now I feel more relatable. I was previously intimidated by the numerous concepts that people mentioned.

Just found your channel. Thanks for the useful Java short course. I used Java many years ago and haven't been back to it until now.. Point and click is great until you have a problem. At that 'point' understanding basic programming and how data types are dealt with is exceedingly important when it comes to debugging and finding those pesky little bugs.

Stop writting stupid comments such as Java is dead and etc, Java is very great and nice programming lenguage. Im learning it for a long time and I like it. If its hard to you than do not hate Java for no reason.

Been programming and aware of the trade for about six years now, and going BACK to my first language, Java, it's changed quite a lot from when I was using it first starting out. In between then, I dabbled lightly in python and Ruby, but really went hard on C and C++. Learning those two, really decent at C, really helped me get a better grasp on Java. It is verbose, but I personally like that about it. As it doesn't leave you with *too* many questions. It's also pretty damned fast and you can really do pretty much anything with the language. I will say, though: had I not gotten a good grasp of C and went deeper into C++, Java would be much more complicated and confusing to me.

I'm currently studying Java, it's my first Programming Language and been doing it for about a month at the ITAcademy locally, I know a month is not enough to learn it or master it, but I'm going at it one step at a time. Of course there is a million questions in my mind about every single line, keyword, input and so on but they get answered as I go.
I appreciate being able to see these videos as a sort of an additional tutorial.

[justindouglas]

been waiting so long for you to do a java course man have i waited!!

[bogdanbilcan]

Java has methods but at the same time methods, functions and procedures are not all just different words describing same thing, method is like an encapsulation of the other 2 related to java coding, where function is a piece of code that takes input parameters and returns something and procedures could have nor not have inputs and performs some actions that don't return anything.

Java always been my favorite language.. I learned it at university, I find the OOP very much elegant and intuitive. Second favorite must be C# (use it at work for pretty much everything)

[teddybear_lost]

I learned programming with Java and it's a very good language to start learning programming in and understand the basic concept of OOP and programming. However, I don't enjoy programming in Java and avoid it as much as possible. It's just not fun programming in, and you often need more complex code in Java than in other languages to do the same thing. I really enjoy Python and I'm a huge fan of Ruby and Ruby on Rails.

[kopilkaiser]

Dude you taught JAVA so well 😊 I liked your tutorial video on JAVA. I was able to learn the fundamentals thanks to you. Moreover, you do a lot of fun which makes your content enjoyable and fun to watch 😂🤪
