When should we use exception handling in java?
Exception handling should be used in Java in all cases where you as a programmer suspect that your code might throw some exceptions or create errors that might look ugly when a user is using the application. In such cases you use exception handling to catch and handle the exception and exit gracefully. You use the try - catch block in Java for exception handling.

Does the Java exception mechanisms with try and catch clauses contribute to failure tolerance?
Yes, the purpose of the try-catch construct in Java is to help the system handle failure gracefully. Exception handling allows developers to detect errors easily without writing special code to test return values. Even better, it lets us keep exception-handling code cleanly separated from the exception-generating code. It also lets us use the same exception-handling code to deal with a range of possible exceptions.
