+# CSCI 380-04: Assignment 1 - Due by 11:59 PM, Feb 19th, 2019
+* * * 
+
+	 This assignment is meant to introduce you to git, Android Studio, and Java fundamentals.
+	 Complete each part of the assignment as separate git commits. Any assignment that's completed, 
+	 but uses only one giant commit will have 10% taken off. If you don't already have 
+	 Android Studio and git set up on your computer, follow the instructions here before continuing: 
+	 - https://developer.android.com/training/basics/firstapp/
+	 - https://git-scm.com/book/en/v2/Getting-Started-Installing-Git
+	 
+# Part 0 - Reading
+Read the following before attempting this assignment. Make sure to follow the naming convention below in 
+your assignments. You will be deducted 1% for each naming convention violation.
++ [https://leanpub.com/aprimeronjava/read](https://leanpub.com/aprimeronjava/read)
++ [https://google.github.io/styleguide/javaguide.html#s5-naming](https://google.github.io/styleguide/javaguide.html#s5-naming)
+
+# Part 1 - Github Setup - 5%
++ Create a Github account
++ Once your Github account is created, make sure to authenticate with an SSH key (see [https://help.github.com/articles/connecting-to-github-with-ssh/](https://help.github.com/articles/connecting-to-github-with-ssh/)).
++ Create a new **private repo** called `assignment1` on your personal Github account (see [https://help.github.com/articles/creating-a-new-repository/](https://help.github.com/articles/creating-a-new-repository/)). Don't initialize with a readme, since you'll just be importing this
+existing project to your new repo.
++ In terminal, cd into a directory where you'd like to keep your projects.
++ Clone this repo using the following command:
+    + `git clone https://github.com/bhargman/assignment1.git`
++ Once your repo is cloned, `cd` into it using terminal, and use the following commands to set the remote to your new repo and push your project:
+    + `git remote set-url origin [email protected]:[yourGithubUserName]/assignment1.git`
+    + `git push -u origin master`
++ Add me as a collaborator (username : `bhargman`) to your private repo (see [https://help.github.com/articles/inviting-collaborators-to-a-personal-repository/](https://help.github.com/articles/inviting-collaborators-to-a-personal-repository/)).
+    + **If you don't do this step, I'll have no way of grading your assignment**
+
+# Part 2 - Android Studio - 5%
++ Import your `assignment1` repo into Android Studio
++ In the main Android Studio window, tap on "Open an existing Android Studio project"
++ Browse to your `assignment` folder and select to open it
++ Android Studio will now load the project and you should be able to do the rest of this assignment
+
+# Part 3 - Primitives - 10%
+Update `Primitives.java` to include the following:
++ `private` fields for every type of primitive.
++ Constructor with parameters to initialize every primitive field.
++ Update the `print()` method in `Primitives.java` that will print each primitive value on a new line, with the format `"variableName : value"`
++ Add a main method to `Primitives.java` that creates an instance of `Primitives` with name `primitives`, and calls `primitives.print()`.
+
+# Part 4 - Arrays - 30 %
++ Update the constructor in `Arrays.java` to initialize the `squares` array with the first 10 *even* squares (exclude 0).
++ Update the `printSquaresBackward()` method in `Arrays.java` to print each value of the `squares` array in backwards order.
++ Add a main method to `Arrays.java` that creates an instance of `Arrays` with name `arrays`, and calls `primitives.printSquares()`.
+
+# Part 5 - Classes - 50%
++ Create a new `package` in `com.csci38004.assignment` called `shapes`.
++ All work for this part should be done in the `shapes` package.
++ Create a new `interface` called `Shape`.
++ Add `double area()` and ` double perimter()` methods to the `Shape` interface.
++ Create two classes called `Circle` and `Rectangle` which implement `Shape`.
++ Add reasonable fields to the `Circle` and `Rectangle` classes which will allow you to calculate the area and perimeter of each shape.
++ Add constructors to `Circle` and `Rectangle` so you can initialize your fields.
++ Implement the `area()` and `perimeter()` methods for `Circle` and `Rectangle`.
++ Create an interface called `Shape3D`.
++ Add `double volume()` method to `Shape3D`.
++ Create a class called `Cyclinder` which extends `Circle` and implements `Shape3D`.
++ Add and initialize any required fields that you may need to calculate a cylinder's volume.
++ Keep in mind that the `Cylinder` class will have access to its parent (`Circle`) class' methods. Use this to your advantage to implement the `volume()` method.
++ Create a class named `ShapeRunner` with the following main method:
+```
+public static void main(String[] args) {
+    Shape circle = new Circle(2.0);
+    Shape rectangle = new Rectangle(4.0, 2.0);
+    Shape3D cylinder = new Cylinder(4.0, 1.0);
+
+    System.out.println("Circle:");
+    System.out.println("Area: " + circle.area() + ". Perimeter: " + circle.perimeter());
+    System.out.println("\nRectangle:");
+    System.out.println("Area: " + rectangle.area() + ". Perimeter: " + rectangle.perimeter());
+    System.out.println("\nCylinder:");
+    System.out.println("Volume: " + cylinder.volume());
+}
+```
++ Notice how the shapes are declared with their interfaces instead of their concrete types. This allows for more flexibility when
+trying to extend an application, but also makes sure that you are able to only access methods on the interface's contract. Feel free
+to play around with different values to test your implementations, but when submitting your final assignment, make sure to leave this
+`main()` method as written here.
