Best Answer.
Unchecked exceptions :
•represent defects in the program (bugs) - often invalid
arguments passed to a non-private method. To quote from The
Java Programming Language, by Gosling, Arnold, and
Holmes : "Unchecked runtime exceptions represent conditions
that, generally speaking, reflect errors in your program's
logic and cannot be reasonably recovered from at run time."
•are subclasses of RuntimeException, and are usually
implemented using IllegalArgumentException,
NullPointerException, or IllegalStateException
•a method is not obliged to establish a policy for the
unchecked exceptions thrown by its implementation (and they
almost always do not do so)
Checked exceptions :
•represent invalid conditions in areas outside the
immediate control of the program (invalid user input,
database problems, network outages, absent files)
•are subclasses of Exception
•a method is obliged to establish a policy for all checked
exceptions thrown by its implementation (either pass the
checked exception further up the stack, or handle it
somehow)
It is somewhat confusing, but note as well that
RuntimeException (unchecked) is itself a subclass of
Exception (checked).
