 Things to watch out for:
-  - not initializing a field ( fields are private, to encapsulate)
+  - Constructors should initialize the class's  fields  (fields are ''private'', to encapsulate)
-  - accidentally making a local variable instead of initializing a variable in a constructor
+  - **Do not** use the type in the constructor- this accidentally makes a local variable instead of initializing the classes field that has the same name.
   - remember to make methods public, and don't forget to use () for the parameter list, even if there are no parameters
   - local variables are never public nor private

   - Variables are declared ONLY ONCE, not every time.
   - **Do not** assign a value to a parameter inside a method unless you are asked to (also a AP scoring penalty called **Destruction of data**)
-  - return statement on a constructor, or a method that isn't supposed to return something (a 'void' method).  This too has a AP scoring penalty)
+  - **Never** use ''return'' in a constructor

 Finally, please remember to get a good night's rest and a healthy breakfast!
 Good Luck!
