== common tips to determine if code compiles ==<br />
* Keep an eye out for all reserved words [[Chapter 1]]<br />
* Verify brackets - {} - and parentheses-()- are being used correctly.[[Chapter 1]]<br />
* Verify new is used appropriately for creating objects [[Chapter 1]]<br />
* Ignore all line indentation especially with if-then statements that do not use brackters[]. [[Chapter 2]]<br />
* Make sure operators use compatible data types, such as the logical complement operator(!) only applied to boolean values, and arithmetic operators (+,-,++,--) only applied to numeric values [[Chapter 2]]<br />
* For any numeric operators, check for autimatic numeric promotion and order or operation when evaluating an expression [[Chapter 2]]<br />
* Verify switch statements use acceptable data types [[Chapter 2]]<br />
* Remember == is not the same as equals(). [[Chapter 3]]<br />
* String values are immutable [[Chapter 3]]<br />
* Non-void methods must return a value that matches or is a subclass of the return type ot the method [[Chapter 4]]<br />
* If two classes are involved, make sure access modifies allow proper access of variables and methods [[Chapter 4]]<br />
* Nonstatic methods and variables require an object instance to access [[Chapter 4]]<br />
* If a class is missing a default no-argument constructor or the provided constructors do not explicitly call super(), assume the compiler will automatically insert them [[Chapter 5]]<br />
* Make sure abstract methods do not define an implementation, and likewise concrete methods always define an implementation [[Chapter 5]]<br />
* You implement an interface and extend a class [[Chapter 5]]<br />
* A class can be cast to a reference of any superclass it inherits from or interface its implements [[Chapter 5]]<br />
* Checked exceptions must be caught, unchecked exceptions may be caught but do not nedd to be [[Chapter 6]]<br />
* try blocks require a catch and/or finally block for the OCA exam [[Chapter 6]]<br />
== Tips during taking the test ==<br />
* Answer all Questions-> Guess an answer<br />
* Understand relationship between answers<br />
* check for answers do not compile due to line x<br />
* have a look at the starting linenumber, maybe includes are needed for complie, if it starts with 1...<br />
* skip hard questions and mark it for "review"<br />
== Optimizing your time ==<br />
<br />
* 120 min remaining start the exam<br />
* 90 min remaining 1/3 finished<br />
* 60 min remaining 2/3 finished<br />
* 30 min remaining fist pass pf all questions complete<br />
* 5 min finished questions which were marked for "review"<br />
<br />
