Question
Chapter 7, Problem 7RE
Program Plan Intro
Exception:
- It is nothing but an undesirable or unexpected event that occurs at run time which interrupts the normal flow of the program’s commands.
- Exception handling is a
mechanism that handle runtime errors like “ClassNotFoundException”, “SQLException”, and so on. - An advantage of exception handling is to maintain a flow of the
program. - An exception can be handled using “try” and “catch” block.
Catching exception:
Java virtual machine (JVM) searches to handle the error in “catch” clause at that time of exception in the program. So “try-catch” statements are used in order to handle those exceptions. The following are the main keywords used in exception handling.
- “try” block: Try block contains the block of statements to monitor the exception and it thrown the exception.
- “catch” block: Catch block catch exception thrown by the try block to handle it.
Types of exceptions:
There are two types of exceptions. They are:
- Checked Exception
- Unchecked Exception
Explanation of Solution
Unchecked Exception:
- It specifies an error in the code and does not need to be explicitly handled with a “try/catch” block...
Explanation of Solution
Justification:
- Exceptions that the user need to declare with the “throws” reserved word is checked exception...

The Test-and-Set instruction is used in hardware to achieve synchronization. It can be defined in the following way: function Test-and-Set (var target: boolean): boolean; begin Test-and-Set:= target; target := true; end; Now show how the Test-and-Set instruction can be used to protect a critical region and hence achieve mutual exclusion (do not worry about satisfying the bounded waiting condition).

But to roll and smoke a cigarette, the smoker needs three ingredients: tobacco, paper and matches. One of the smoker processes has paper, another has tobacco and the third has the matches. The agent has an infinite supply of all three materials. The agent places two of the ingredients on the table. The smoker who has the remaining ingredient then makes and smokes a cigarette, signaling the agent on completion. The agent then puts out another two of the three ingredients, and the cycle repeats. Given below is a solution to the Cigarette-Smokers Problem. Give initial conditions for the semaphores as well as plausible values for the variables i & j and r & s, such that the agent and smokers are synchronized. Write a couple of sentences on why these initial conditions are necessary and sufficient. Solution: var a: array [0..2] of semaphore (initial condition =…arrow_forward
