Repo to practice java & robot programming

List of tasks

These are tasks to complete in order to get a grasp of Java basics & move onto programming robot. After you complete each task you should commit it saying you "Completed Task [X]". After you complete a group of tasks, push your code your branch. This repo will have commented code on how to complete each task if you need extra assistance.

Basics

1. Print to console "Hello World".
2. Multiply 2 numbers & print the result (Do this with int, double, and float).
3. Create a private method for printing to console, and call it from main().
4. Add a string paramater to that method which it will print. Then call this method from the main() method.
5. Create a constructor & initlize a boolean value.
6. Create a new class & add a constructor. Then make an object of it inside your main class.
7. Add a public method to your new object & call it from your main class.
8. Create a new class with a static method to return a string. From your main method call the method & print the returned string.

Intermediate

9. Create a new class called "Robot". Inside add 2 variables for X & Y position (By default 0), along with getter methods and methods to move the robot (Increase or decrease values).
10. Create a new instance of the "Robot" in your main class & move the robot foward. Then print out the current position.
11. Have the robot instance drive in all 4 directions & print out the coordinates after each drive.
12. Created a boolean in the Robot Class called "Enabled", and set it to false by default. Then add 2 public methods for changing the enabled state. Along with making your move methods check the robot is enabled
13. Make a private start() method in your main class, and call it from the constructor. In the start method enable the robot & have it drive foward 4 times, using a for loop.
14. Next create a private stop() method and call it at the end of the start method. (For fun, add a movement call after the stop() to see if it still drives. If you programmed it right it shoudln't).
15. Create a new class called Joystick. Add a constructor which requires an int for the port number. Then, create a public final int which gets set to the argument passed in the constructor. (Also, the member variable should be named the same as the constructor variable. Hint: Use this.)
16. Create a new instance of the joystick & supply a port number in your class.

Robot Programming

Congrats! You're ready to programming the robot.

17. Create a simple robot template with TankDrive functionality.
18. Add an autonomous program that drives forward & backwards.
19. Add turning to this autonomous program.
20. Add in pneumatic functionality.
21. Create 2 buttons to lower & raise the door.
22. Make a new autonomous program that drives foward, lowers the door, drives backward, and raises the door.
23. Make a new autonomous program that drives foward, turns left, lowers the door, raises the door, and goes back to the start position.
24. Create a private method to handle lowering & raising the door. Then call these from your autonomous program & opcontrol.
25. Create a method that drives the robot in a direction, but uses the inverse of the pramater. Then create an autonomous program that drives in a circle using your new method. Have fun!

All done!
