Run Time Errors In Java
vote favorite 7 This question already has an answer here: Runtime vs Compile time 19 answers In one of my prof slides on ploymorphism, I see this piece of code with a couple of comments: discountVariable = //will produce (DiscountSale)saleVariable;//run-time error discountVariable = saleVariable //will produce //compiler error As you can see, it says in the first casting statement that it'll produce run-time error and in the other one it compile time error hackerrank says it'll produce compiler error. What makes these errors? and how they differ from each other? java compiler-errors share|improve this question edited Nov 16 '12 at 21:10 The Unfun Cat 4,23374064 asked Feb 27 '12 at 20:31 AbdullahR 1982414 marked as duplicate by assyliasjava Users with the java badge can single-handedly close java questions as duplicates and reopen them as needed.

The guy is trying to learn, downvotes are unnecessary. –JohnFx Feb 27 '12 at 20:35 3 Doesn't matter if it has addressed my example or not, what really matters is that I got the answer clearly. That guy explained it in a simple way that can be easy to understand to a naive programmer like me. –AbdullahR Feb 27 '12 at 20:54 Did you read the stackoverflow.com/faq ? –user647772 Feb 27 '12 at 21:00 Thank you AbdullahR, I hoped that from my example you could comprehend the difference and extrude the information you needed for your homework without me handing you the answer you need for your homework directly. &n

It is one of the hardest concepts to learn, especially for people without much background in programming languages. To approach this problem, I find it helpful to ask What invariants does the program satisfy? What can go wrong in this phase? If the phase succeeds, what are the postconditions (what do we know)? What are the inputs and outputs, if any? Compile time The program need not satisfy any invariants. In fact, it needn't be a well-formed program at all. You could feed this HTML to the compiler and watch it barf... What can go wrong at compile time: Syntax errors Typechecking errors (Rarely) compiler crashes If the compiler succeeds, what do we know? The program was well formed---a meaningful program in whatever language. It's possible to start running the program. (The program might fail immediately, but at least we can try.) What are the inputs and outputs? Input was the program being compiled, plus any header files, interfaces, libraries, or other voodoo that it needed to import in order to get compiled. Output is hopefully assembly code or relocatable object code or even an executable program. Or if something goes wrong, output is a bunch of error messages. Run tim
