Checked Exceptions:
A checked exception is any subclass of Exception (or
Exception itself), excluding class RuntimeException and its
subclasses.
You should compulsorily handle the checked exceptions in
your code, otherwise your code will not be compiled. i.e
you should put the code which may cause checked exception
in try block. "checked" means they will be checked at
compiletime itself.
There are two ways to handle checked exceptions. You may
declare the exception using a throws clause or you may use
the try..catch block.
The most perfect example of Checked Exceptions is
IOException which should be handled in your code
Compulsorily or else your Code will throw a Compilation
Error.
Unchecked Exceptions :
Unchecked exceptions are RuntimeException and any of its
subclasses. Class Error and its subclasses also are
unchecked.
Unchecked runtime exceptions represent conditions that,
generally speaking, reflect errors in your program's logic
and cannot be reasonably recovered from at run time.
With an unchecked exception, however, compiler doesn't
force client programmers either to catch the exception or
declare it in a throws clause.
The most Common examples are ArrayIndexOutOfBoundException,
NUllPointerException ,ClassCastException
