Consider the following method: public static Exception convert (Exception e) { String msg - e.getMessage (: NullPointerException npe - new NullPointerException (msg); return npe:

X1155: Throwing an Exception The method below takes in a String parameter representing a username. It should throw an Exception if the username is less than 3 characters long. The method correctly throws the exception, but something is still missing. Fix the problem. Your Answer: Feedback 1 public String validateUser (String userName) 2|{ 3 45 6 7 8|} 9 if (userName.length() < 3) { throw new Exception("userName is too short"); } return userName; Check my answer! Reset Your feedback will appear here when you check your answer.

in c++ Define a new exception class named “BadValueException” that must inherit from the exception class. It will manage and capture the general invalid integer and double value. It must be able to describe the reason for the error and save away the erroneous value. In another words, when the caller catches the exception and receives this object, it must know what the reason for the exception is and the actual bad value that caused the exception.

True or False  We can define a custom generic 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.

Instructions: Exception handing Add exception handling to the game (try, catch, throw). You are expected to use the standard exception classes to try functions, throw objects, and catch those objects when problems occur.  At a minimum, you should have your code throw an invalid_argument object when data from the user is wrong.    File GamePurse.h: class GamePurse { // data int purseAmount; public: // public functions GamePurse(int); void Win(int); void Loose(int); int GetAmount(); };   File GamePurse.cpp: #include "GamePurse.h" // constructor initilaizes the purseAmount variable GamePurse::GamePurse(int amount){      purseAmount = amount; } // function definations // add a winning amount to the purseAmount void GamePurse:: Win(int amount){      purseAmount+= amount; } //  deduct an amount from the purseAmount. void  GamePurse:: Loose(int amount){      purseAmount-= amount; }   // return the value of purseAmount. int GamePurse::GetAmount(){      return purseAmount; }   File…

-Modify your parameter constructors to call your set methods. This will cause validation of the parameter.-Create an exception class named TractorException.-Modify your setters to throw TractorException if invalid values are passed in. You may also need to add a throws clause to your parameter constructors. This way we will not have any print methods in our Tractor object defining class-Modify your main method to try and catch exceptions. It should catch TractorExceptions and general Exceptions and display an appropriate message   import java.util.*; class TestException {     public static void main(String s[]) {            Scanner scanner = new Scanner(System.in);                boolean valid=false;                // validation loop        while (!valid) {           try {               System.out.println("Enter integer:");               int number = scanner.nextInt();  // may throw an exception               System.out.println("You entered "+ number);               valid=true;…

pls help asnwer this code in c++

Suppose there exists a catch handler that matches the exception object type perfectly. Under what circumstances may exception objects of this type be treated differently?

Time Converter 1. Write a program that converts dates from a numerical month-day format to alphabetic month-day format. IE 1/31 or 01/31 would have an output of January 31. 1. User enters the month and day as a single string. It is then converted. (10%) 2. Create 2 exception classes (20%) 1. MonthException thrown for invalid months 2. DayException-thrown for invalid days for the given month 3. You can assume Feb is always 28 days 2. This should run in a for loop and end when a user is done entering dates (70%)
