[Java Basics]

 Developer Tools - Eclipse (for writing code) and GitHub (for collaboration and version control)
 Hello World - A simple example of a Java program
 Data Types - Formats for storing information
 Variables - Data structures that store values
 Operators - Operations that can be performed on or between variables/values
 Control Statements - Statements that change the order in which code is executed
 Comments - Code that is not executed by the compiler

[Object-Oriented Programming]

 Objects and Classes - Collections of variables and methods
 Methods - Actions that objects can perform
 Instantiation - Creating a new object
 Fields - Variables that an object possesses
 Modifiers - Keywords that affect properties of a variable, method, or class
 Type Casting - Converting between different data types
 Imports - Bringing outside code into a program
 Math - A library of more advanced mathematical functions
 String - A class for manipulating strings of text
 Array - A data structure that stores multiple values in a single variable
 System I/O - Communicating with the program through the console

WPILib Basics

 FRC Updates - Installing the FRC software at kickoff or on new computers
 Iterative Robot - A class containing robot methods that are repeatedly called
 WPILib - The FRC library
 Actuators - Components on the robot that can perform actions (outputs)
 Sensors - Components on the robot that can collect data (inputs)
 Joysticks - Devices that the operator uses to control the robot (inputs)
 RobotDrive - A class for controlling the robot drivetrain
 FRC DriverStation - A program for operating the robot
 SmartDashboard - A program for displaying robot output to the operator
 Webdash - The online interface for the RoboRIO

Command-Based Programming

 Robot Builder - A program for generating the general framework of the robot code
 Robot Map - A class that maps actuators and sensors to their ports on the RoboRIO
 Subsystems - Parts of the robot that perform individual tasks
 Commands - Actions that the robot can perform
 Command Groups - Groups of actions for the robot to perform in sequence or in parallel
 Operator Interface - A class that maps the joysticks and buttons with robot commands
 Robot - An Iterative Robot class that manages the rest of the robot project
 SmartDashboard Continued - Using additional features of SmartDashboard
 Timer - A class for keeping track of real time

Inheritance

 Subclasses - Extensions of another class that inherit its code
 Overriding - Code in a subclass replacing code from a superclass
 Super - Accessing methods and constructors of a superclass
 Interfaces - Collections of methods that a class is required to implement
 Inheritance Modifiers - Using abstract, default, final, and access modifiers with inheritance

Design Principles

 Code Reuse - Not writing the same code twice
 Encapsulation - Keeping information self-contained
 Polymorphism - Using different data types interchangeably
 Type Safety - Preventing incorrect use of data types
 Efficiency - Writing algorithms that use less processing power
 Memory Management - Garbage collection and avoiding memory leaks

Additional Topics

 Nested Classes - Defining a class inside of another class
 Generics - Generic datatypes that can represent any datatype
 Enums - A special data type to define a collection of constants
 Exceptions - Errors thrown at runtime
 Threading - The sequence in which code is executed
 I/O Streams - Sequences of input or output information
 Graphics - Visual effects displayed on the screen by the program
 Annotations - A system for documenting code
 Regular Expressions - A technique for sorting through Strings
 Dynamic Programming - A technique for making algorithms more efficient
 Functional Programming - A style of programming that avoids changes of state
 Stream Operations - Functional programming techniques for manipulating collections

Projects

 Custom Widgets - Creating new widgets for the SmartDashboard
 Device Characterization - Investigating the usage of various actuators and sensors
 Motion Profiling - Calculating a trajectory for the robot to follow
 NetTables Client - Reading data from network tables
 PID Control - A type of feedback loop
 RoboRIO Files - Storing files on the RoboRIO
 Robot Simulator - A program that simulates the robot for testing purposes
 Vision - Analyzing input from the camera
