Checked exception should be wrapped in a try-catch block or SPECIFIED as THROWS clause where as there is no such requirement for unchecked exception.

Failure to provide exception handling mechanism for checked exception result in compiler error whereas no compile time error for unchecked exception.

Checked exceptions are DESIGNED to reduce the number of exceptions which are not properly handled and where there is a reasonable chance for recovery. UnCheckedExceptions are mostly programming errors.
