Hi,
Throwable is parents of all Exception classes in Java, Exception and Error are direct child/subclasses of Throwable.
Error are Non-recoverable. Where as Exception are recoverable.
Exception have two category.
1. Checked
IOException
FileNotFoundException
SQLException
2. Unchecked
ArrayOutofBoundException
NullPointerExecption
ArithmeticException
