-It is a good idea to review your homework, labs, and the powerpoint slides (in [[ https://classroom.google.com|Google Classroom]]). Last year's quiz questions were posted at [[https://plusportals.com/saintfrancishs| PlusPortals]].  The file is called "Qtr 1 Quiz Review Chapters 1-6".  Password for the PDF of the questions is the Franciscan virtue Fall 2018!  To check your work, go to  [[https://quizizz.com/join]] and enter game code **024682** on [[http://quizizz.com|quizizz.com]]

 Don't forget that you don't need a computer to practice writing code at [[https://codingbat.com/java|https://codingbat.com/java]].  [[https://codingbat.com/java/Warmup-1|"Warm up"]] and [[https://codingbat.com/java/Logic-1|"logic"]] are good categories to practice.  You also may wish to try these {{ :practice_frq_qtr_1.pdf |practice free response }} quizzes from the past.
 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
+  - **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 none
+  - Remember to make fields ''private'' and methods ''public'',
-  - local variables are never public nor private
+  - Remember local variables are **never** public nor private
-  - dangling else statements (p 148)
+  - Remember method names should use () for the parameter list, even if there are no parameters
+  - Watch for dangling else statements (p 148) - without brackets, the last ''else'' belongs to the previous ''if''
   - forgetting to have a method return something of the correct type
-  - not to add a System.out.print were no printing is requested (This can be a 1 or 2 point 'Extraneous code that causes side effect' penalty on the AP Exam)
+  - **Do not** add a ''System.out.print'' when no printing is requested (This can be a 1 or 2 point **Extraneous code that causes side effect** penalty on the AP Exam)
-  - using local variables that you don't declare ( also a AP scoring penalty)
+  - **Do not** use local variables before first declaring them ( also a AP scoring penalty).
-  - changing a value referenced by parameter or destroying data in a parameter (also a scoring penalty)
+  - Variables are declared ONLY ONCE, not every time.
-  - 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)
+  - **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**)
+  - **Never** use ''return'' in a constructor
+  - **Do not** ''return'' something when writing a ''void'' method ( a method that isn't supposed to return something (This too has a AP scoring penalty)
 Finally, please remember to get a good night's rest and a healthy breakfast!
 Good Luck!
