doubt in Exceptions

[kittu karan]

HI,
How can we know whether it is checked Exception or uncheckedException like ClassNotFound,SQLExceptin, etc.

Thanks in advance.

Hi,

All exceptions that are subclasses of RuntimeException are UNCHECKED, which means they are not being checked by the compiler whether you have followed the handle-or-declare rule.

All exceptions that are subclass of Exception but not of RuntimeException are checked exceptions (meaning, they are being checked by the compiler whether you have followed the handle-or-declare rule.)

To add to what said by Jart,

Error and it's sub-classes are also not checked by compiler.

Throwable and its sub-classes are checked by compiler
