A)catch method

Question 6

A)exception handling
C)exception processing

C)catches the exception
B)stops the exception
D)throws the exception

Question 9

You can create your own exceptions.

Question 10

Using a traditional error-handling method to avoid dividing by 0 prevents the error and makes the method more flexible.

Question 11

____ is thrown when an arithmetic operation produces a result for which the value is greater than the assigned memory location can accommodate.

A)IndexOutOfRangeException
C)NullReferenceException
B)ArrayTypeMismatchException
D)OverflowException

Question 12

A ____ is one that sends an exception object out of a method so it can be handled elsewhere.

A)catch statement
C)catch block
B)throw method
D)throw statement

Question 13

In object-oriented terminology, you "____" a segment of code that might cause an error.

A)try
C)throw
B)catch
D)observe

Question 14

When a program throws an exception, you always have to deal with it.

Question 15

Dividing by 0 is an error in every programming language because it is an operation that is not defined mathematically.

Question 16

Probably the most often used error-handling solution before object-oriented programming was to make a decision before working with a potentially error-causing value.

Question 17

A catch block consists of four different elements: the keyword catch, followed by parentheses that contain an exception type and identifier, statements that take action to handle the error condition, an endcatch statement, and a return statement.

A)Error
C)RuntimeError

A)IndexOutOfRangeException
C)NullReferenceException
B)ArrayTypeMismatchException
