[39] The Java Tutorials discourage catch-all exception handling as it may catch exceptions "for which the handler was not intended". [40] Still another discouraged circumvention is to make all exceptions subclass RuntimeException. [41]
An exception handling mechanism allows the procedure to raise an exception [2] if this precondition is violated, [1] for example if the procedure has been called on an abnormal set of arguments.

An exception is when a processor is designed to use a particular bytecode directly as its machine code, such as is the case with Java processors. Machine code and assembly code are sometimes called native code when referring to platform-dependent parts of language features or libraries. [16]
