NEW QUESTION # 100
Given the classes:
*AssertionError
*ArithmeticException
*ArrayIndexOutofBoundsException
*FileNotFoundException
*IllegalArgumentException
*IOError
*IOException
*NumberFormatException
*SQLException
Which option lists only those classes that belong to the unchecked exception category?
- A. AssertionError, IOError, IOException
- B. FileNotFoundException, IOException, SQLException
- C. ArrayIndexOutOfBoundException, IllegalArgumentException, FileNotFoundException
- D. AssertionError, ArrayIndexOutOfBoundsException, ArithmeticException
- E. ArithmeticException, FileNotFoundException, NumberFormatException
Answer: D
Explanation:
Not B: IOError and IOException are both checked errors.
Not C, not D, not E: FileNotFoundException is a checked error.
Note:
Checked exceptions:
*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
*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)
Note:
Unchecked exceptions:
*represent defects in the program (bugs) - often invalid arguments passed to a non-private method. To quote from The Java Programming Language, by Gosling, Arnold, and Holmes: "Unchecked runtime exceptions represent conditions that, generally speaking, reflect errors in your program's logic and cannot be reasonably recovered from at run time."
*are subclasses of RuntimeException, and are usually implemented using IllegalArgumentException, NullPointerException, or IllegalStateException
*method is not obliged to establish a policy for the unchecked exceptions thrown by its implementation (and they almost always do not do so)
