Hi . I have a few questions :
1.When exam asks about exceptions is it also about errors? Are errors considered exceptions or are only classes that extend Exception class?
2.Which particular methods of String,StringBuilder,ArrayList etc. are required on the exam? I know these classes have much more methods than are mentioned in exam books and simulators,an i'm wondering if i should learn methods like split,join,regionMatches,subSequence etc.
3.Are there many questions with missing brackets ? I cant remember having any on exam simulators .Should i even pay attention to this on real exam?
1) The OCP exam asks about exceptions, but not about how to create/use custom exceptions. You don't have to worry about extending the Exception class.
Any questions about exceptions will be more along the lines of
"What exception occurs with the following code?"
"What is the result of the following code?"
2) You should learn about split, join and subSequence as there will be some questions about String, StringBuilder and ArrayList on the exam.
As these questions change from day to day, there is chance that you may not be asked any questions about these objects/methods.
