Handling
Exceptions
•In Java, exceptions are
said to have been “thrown.” In other languages, they
may be “raised.”
•It is the programmers
responsibility to write code that anticipates the occurrence of an exception and keeps the program from
crashing.
•The code that does this is
said to “handle” the exception and is called an exception handler.
•If the programmer
doesn’t write code to “handle the exception”, the default exception handler does. It prints an error message
and crashes the program which isn’t very satisfactory.
