In the last lesson, you learned how to write a Hello World program, and you also learned some cool things that made it work. Now, we will learn about the various data types available in Java. A data type is just the type of data that can be stored in a variable, as we will see in just a moment. There are nine data types which we will go over.

In this tutorial, I will cover data types and variables in Java.

I don't think Five Nights at Freddy's isn't made with this yet, but hopefully someone will.

Because I have coding experience in both languages.

Just because Hello World is the same in both languages doesn't mean both languages are the same. There are a lot, and I mean A LOT of differences between the two.

"Houston, we have a problem."

Oh, no. This application does not harm your 3DS. If an app someone makes is broken, then just quit, come back, and it's good as new. No, SmileBASIC won't harm your 3DS in any way.

Yes, tell me. I have limited knowledge of SmileBASIC, but hopefully I would be sure to know.

This is a tool to make your own games and applications using the SmileBASIC programming language. It's fun, and I recommend you get it.

Just letting you know, there's a second platform underneath the top platform. Imo, I think the UI for this game should simply be a play button to start the game.

That was the starting screen of Petit Computer!

I'll be covering data types and variables.

You can use only one System.out.println to print out one message, but that message can be typed up on different lines! Like this: System.out.println("This string " + "can be combined " + "with other strings " + "using addition?!"); And the output would be this: This string can be combined with other strings using addition?!

I don't think that concerns Java, sorry.

Nah, there's just no other way of saying it.

This is nothing more than a simple programming language, whose syntax highly emulates that of an interpreted language.

Here's the final program: public class HelloWorld{ public static void main(String[] args){ System.out.println("Hello world!!!!!"); } } Once you have finished writing the program, click that green play button near the top of the screen. And voila! Your message will be printed to the console below! This concludes Java tutorial #1. Feel free to discuss what you have learned here!

Anything between a pair of double-quotation marks is called a string, a data type we will go over later. You'll also be wondering what that semicolon is doing at the end of that line. Semicolons are used to "terminate" single-line statements, just as a period terminates an English sentence at the end.

Under the line where we defined main, type this one-lined wonder in: System.out.println("Hello world!!!!!"); The System.out.println command is used to "print" things to a console. No, the message "Hello World!!!!!" will not come out of your printer. Within the parenthesis you must type in the message between double quotation marks.

After the closing parenthesis, place another opening brace. Your program should look like this now: public class HelloWorld { public static void main(String[] args){ } } We have created another pair of braces! So we can write our program inside our main method, which is inside our HelloWorld class. We're going to do the fun part now!
