Q: can i raise a standard exception?

q4: a pair of things to be defined for an exception, beside its name?

q: why do some say java try/catch and exception propagation borrowed from pl/sql?
A: "catch or propagate". In other words, uncaught exceptions are propagated.

Q1: When declaring a user-defined exception, is there any content in it?

Q89: a user-defined exception usually signifies a specific (rather than vague) condition. Where is the specific condition specified?
