Thanks for checking out the Demo_Projects! This is a set of examples that gradually introduce new concepts about programming in Java, all within the very IDE (Integrated Development Environment) that you'll test them out in! These project are for VIEWING and EXECUTING (r+x) purposes only, please do not make any changes to the examples, as it will change for everyone (once I finish writing them, I'll lock them so they're read-only and can't accidentily get changed). I encourage you to read each program and try running each one so you can get an idea of the workings of each one. You can also copy the source of each example into your own project so that you can change the code and see what changes what.
That being said, here's an index of the lessons and a short description of each.
01_HelloWorld/
This is the classic introduction to programming for many
different programming languages that prints out a simple
text statement to the screen.
02_Variables/
Introduces the concepts of programming variables. Includes
basic type descriptions, declaration/definition, and retrieval.
03_Conditions/
Introduces if, else if, and else statements. Also briefly
talks about the ternary operator.
04_Operations/
Operations are actions that are taken on data. This section
demonstrates Numerical and Boolean operations that are natively
supported by Java.
05_Loops/
Often in computing, there are tasks that needs to be run
repetitively in order to achieve a certain goal. Loops allow
programs to repeat an action for as long as needed.
