Q10. Which two statements correctly describe checked exception? 

A. These are exceptional conditions that a well-written application should anticipate and recover from. 

B. These are exceptional conditions that are external to the application, and that the application usually cannot anticipate or recover from. 

C. These are exceptional conditions that are internal to the application, and that the application usually cannot anticipate or recover from. 

D. Every class that is a subclass of RuntimeException and Error is categorized as checked exception. 

E. Every class that is a subclass of Exception, excluding RuntimeException and its subclasses, is categorized as checked exception. 

Answer: B,D 

Explanation: Checked exceptions: 

* (B) represent invalid conditions in areas outside the immediate control of the program (invalid user input, database problems, network outages, absent files) 

* are subclasses of Exception It's somewhat confusing, but note as well that RuntimeException (unchecked) is itself a subclass of Exception (checked). 

* a method is obliged to establish a policy for all checked exceptions thrown by its implementation (either pass the checked exception further up the stack, or handle it somehow)
