+# Abstraction 🍵
+
+### Task 🐧
+ - Create an abstract class called Shirt:
+   - Make an instance variable called color
+   - Make a constructor that takes a String for the color & sets it to the instance variable
+   - Make a public method called `getColor()` that returns the name of the color 
+   - Make an empty abstract method called `getDescription()`
+
+ - Create a default class called `T_Shirt` that extends Shirt:
+   - Make an instance variable called size
+   - Make an instance variable called price
+   - Make a constructor that takes in a color, size, price and sets the instance variables (Use super() to call the constructor of Shirt)
+   - Override the method called `getDescription()` that returns the color, size, and price of the T_Shirt
+
+ - Create another default class called 'Jacket' that extends Shirt:
+   - Make an instance variable called price
+   - Make an instance variable called brand
+   - Make a constructor that takes in a color, and price, and sets the instance variables (Use super() to call the constructor of Shirt)
+   - Override the method called `getDescription()` that returns the color, brand, and price of the T_Shirt
+
+### Requirements 🏫
+```
+1. A .java file
+2. Prints the color & size of a T_Shirt
+3. Prints the color & size of a Jacket
+4. Prints the isZip of a Jacket
+5. Prints the total price of the items
