11- When a Python program crashes with an exception, what would you generally expect to find as part of the displayed error output? a. The text "ValueError", which is always included in exception output. b. The number of statements executed before the exception was encountered. c. The dedicated rule yield (DRY) of the program so far. d. A McDonald's job application form, because professional programmers don't make errors. e. The exact time that the exception was raised at. f.

Q3(a). Explain the purpose of exception handling by taking one of the following scenarios. b. Write a piece of Java code that illustrates how you handle the scenario selected in Q3(a)” Scenario 1. Users enter values that are not included in a predefined list.Scenario 2. A potentially corrupt file could be uploaded to your program.Scenario 3. A database query returns some null value.Scenario 4. A remote method invocation returns null value
Modify your last GeoPoint program and add exception handling. Wrap the code inside the main “do another?” loop of your last program with a try block. Add three except blocks. The first will catch a TypeError exception and display “Wrong type of input!” The second will catch an exception of your choice and display a message that makes sense. The third will catch a generic Exception along with its object e and display the message “Something went wrong: “, e so that the error message e is displayed. The code will look something like this (yours may vary): doAnother = 'y' while doAnother == 'y': try …your code here… except TypeError : print "Wrong type of input!" except …exception you picked… : print …your custom message… except Exception,e: print "Something went wrong: ", e doAnother = raw_input('Do another (y/n)? ')
Using JAVA (Catching Exceptions Using Class Exception) Write a program that demonstrates how various exceptions are caught with catch (Exception exception) This time, define classes ExceptionA (which inherits from class Exception) and ExceptionB (which inherits from class ExceptionA). In your program, create try blocks that throw exceptions of types ExceptionA, ExceptionB, NullPointerException and IOException. All exceptions should be caught with catch blocks specifying type Exception.
Java : Write the code segments in main( ) and in methodA( ) for the following scenario: main( ) passes methodA an int variable called a. methodA generates an exception, but does not deal with it, if a is not between 1 and 100. Hint: main will try and catch the exception and methodA throws exception.
C++ You did this way back in Unit 1! But now all of your RomanNumber code is wrapped up in a class, so the "main" program is short and sweet. As before, write a program that accepts entries from the user. If it's an integer, convert to Roman Number and display. If it's a Roman Number, convert to integer and display. If it's neither, thrown an exception and continue to process The action to take here will be to display an error message If the entry is 0 or O (The digit 0 (zero) or the letter O) exit and state how many conversions were done of each type (integer to Roman and Roman to integer) and how many exceptions were thrown. As I said, the main program will be short and sweet. Provide your .cpp code and a screen shot of your program in action. Enter twelve conversions - four integer to Roman, four Roman to integer, and two of each in which the input is invalid so that I can see the exceptions. The thirteenth and final entry will be 0 or O.

PLZ help with the follwoing IN JAVA Suppose that statement2 causes an exception in the following try-catch block: Will statement3 be executed? If the exception is not caught, will statement4 be executed? If the exception is caught in the catch block, will statement4 be executed?
Foundation in java Please provide a basic exception code. Do not use input, output. Please provide code and explain. Thank you. Write the Java code for the following: Write the InvalidGradeException class that will be used below. Write the Java program that reads an integer grade from a user and checks that it is valid (between 0 and 100). If it is invalid an InvalidGradeException will be thrown, stating what the invalid grade is. This will be caught in the main( ) method which will write a message about the invalid grade. If the grade is valid, it is written to the monitor..
Write a program that includes the <exception> header using the pre-processor directive. Then create a class named MyException that inherits all properties from the exception class. In that class create a function what() which basically returns an error message string (“C++ Exception”). Finally inside the main function create a try{}…catch() block and inside the try block create an object of MyException class and use the throw keyword to explicitly throw an exception using this object.(answer this in c++ programming language)
