Checked vs Unchecked Exceptions

In Java only:

• Checked Exceptions are the exceptions that must be handled.
• Unchecked Exceptions (Runtime Exceptions or Erros) can be checked optionally, these include arithmetic exceptions, null objects, and error in using arrays with out of range indexes [1]. Unchecked exceptions are optional, because there can be too many can clutter the code. It is upto the programmer to intelligently use them.
