Question 1

Compared to traditional error handling techniques, exception handling is considered_____ .&#10;A) less efficient&#10;B) more efficient&#10;C) equally efficient&#10;D) either more or less efficient, depending on the situation&#10;E) The two technologies are not comparable.

Accepted Answer

Exception handling is considered more efficient than traditional error handling techniques because it allows for more specific and targeted error handling, which can lead to faster and more efficient resolution of errors.

Question 2

To catch exceptions thrown by a section of code, you must first enclose those lines in a _____block.&#10;A) try&#10;B) finally&#10;C) throw&#10;D) exception&#10;E) None of the Above.

Accepted Answer

To handle exceptions in a section of code, you enclose that code within a "try" block. This allows you to catch and handle exceptions that may occur within that block of code.

Question 3

Exception handling requires that you write code to handle _____.&#10;A) all types of errors&#10;B) only errors that could occur in your code&#10;C) a few of the most common errors&#10;D) only those errors you choose to handle&#10;E) Both b and c.

Accepted Answer

Exception handling allows you to choose which errors to handle, giving you control over which exceptions to catch and manage in your code.

Question 4

Uncaught exceptions_____ .&#10;A) cause a program to terminate unexpectedly&#10;B) occur when no catch block matches the type of the exception&#10;C) should be avoided&#10;D) make programs less user-friendly&#10;E) All of the above.

Accepted Answer

Uncaught exceptions cause a program to terminate unexpectedly because there is no code to handle the error (A). They occur when an exception is thrown but not caught by any catch block that matches the type of the exception (B). It's generally advisable to avoid uncaught exceptions because they can lead to unpredictable program behavior and make the software less user-friendly by not providing a clear indication of what went wrong (C and D).

Question 5

A catch block that does not specify which type of exception it catches _____.&#10;A) is a syntax error&#10;B) is useless; it will not catch any type of exception&#10;C) will catch any type of exception that does not already have a handler defined&#10;D) should be the last catch block in a group&#10;E) Both c and d.

Accepted Answer

A catch block that does not specify which type of exception it catches (often referred to as a "catch-all" block) will indeed catch any type of exception that does not already have a handler defined. It is recommended to place such catch blocks at the end of a group of catch blocks to ensure that more specific exceptions are caught by their respective handlers first.

Question 6

A FormatException generally indicates that _____.&#10;A) the user attempted division by zero&#10;B) a method was passed an argument of the wrong type&#10;C) a method was passed the wrong number of arguments&#10;D) the program contains a syntax error&#10;E) None of the above.

Accepted Answer

A FormatException typically occurs when a method receives an argument of the wrong type, indicating that the format of the data does not match what was expected.
