Checked Exceptions

These are checked during compile time itself. Checked Exceptions should be either handled or the same should be notified with the throws keyword.

Example – SQLException, IOException.

Unchecked Exceptions

These exceptions are checked during runtime. The classes that inherit the RuntimeException fall under unchecked exceptions. It’s not necessary to handle these exceptions.

Example – NullPointerException, ArrayIndexOutOfBoundsException.
