 ====== Programming Concepts ======
+===== Variables =====
+Variables store information for your program including:
+  * Numbers
+  * Text
+  * References to hardware
+===== Variable Examples =====
+<code java>
+// CAN IDs
+public int lfDriveMotorID = 1;
+public int lrDriveMotorID = 2;
+public int rfDriveMotorID = 3;
+public int rrDriveMotorID = 4;
+// Drivetrain Constants
+public Distance wheelDiameter = Inches.of(3);
+public double driveRatio = 1.0/8.45;
+</code>
+===== Variable - Primitives =====
+|  | Type | Description |
+| Boolean | bool | true or false, 0 or 1 |
+| Integers | byte | Whole number from -128 to 127 |
+| ::: | short | Whole number from -32,768 to 32,767 |
+| ::: | int | Whole number from -2,147,483,648 to 2,147,483,647 |
+| ::: | long | Whole number -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |
+| Floating Point | float | Fractional Number Significant to 6 to 7 decimal places |
+| ::: | double | Fractional Number Significant to 15 decimal places |
+| Character | char | Stores a single character/letter or ASCII values |
+===== Variable - Object =====
+  * An object is a collection of variables and methods.
+  * Used to logically group things together in programs.
+    * Example: The Drivetrain object includes all the drive motors
+  * Fundamental part of java
+----
+All variables in Java, except for primitive types, are an object.
