The First thing you need to know is that everything you're going to use in a specific program must be loaded. The first few lines of every Java program are "import" staements.
You see, Java programs like to use as little space as possible, so instead of just loading all possibly-needed files, folders, etc., you save space by importing only the files you need. It may seem like a hassle at times, but it makes everything faster when you actually run the program.
Most of the time you just load simple things like the files that allow to make pictures or words, or sometimes it can be as complicated as to allow you to make 3d polyhedrons. You only load what you need so noone's computer is slowed down by tons of extra, unnessecary files.
Usually to make drawings, you just type in "[graphics variable].draw[which polygon you want to make (or "string" for a group of words)]" and then in parenthesis you type in the coordinates needed, and the words you want to say if you're making a string.
Drawings are very useful. You can even overlap and compound drawings to create complex objects, such as an animal, a house, a television set, or even a person! The possibilities are endless! They're even more infinite if you use 3d drawing, but since I don't know how to do that we'll just move on...
A big part of Java programming is the "if structure". This is a very useful concept that basically means "If this condition is true, then proceed with the following statement(s), but if it is false, do nothing." (The "if/else structure", another key structure, is basically the same, except it will still do something if the condition is false.) It's used in many java programs, but I had no use for it in my program.
So now you know some of the basics!
