Q)  What is the differance between Checked and Unchecked Exceptions ?


Ans)

Checked exceptions are generally those from which a program can recover & it might be a good idea to recover from such exceptions programmatically. Examples include FileNotFoundException, ParseException, etc. A programmer is expected to check for these exceptions by using the try-catch block or throw it back to the caller

On the other hand we have unchecked exceptions. These are those exceptions that might not happen if everything goes well, but they do occur. Examples include ArrayIndexOutOfBoundException, ClassCastException, etc. Many applications will use try-catch or throws clause for RuntimeExceptions & their subclasses but from the language perspective it is not required to do so. These should be resolved by following good Coding standards and having code reviews ect.,
