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.

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%)
JAVA EXCEPTION HANDLING:Define a new exception, called ExceptionLineTooLong, that prints out the error message "The strings is too long". Write a program that reads phrase and throws an exception of type ExceptionLineTooLong in the case where a string is longer than 80 characters.

- Define an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using this zero- argument constructor, getMessage should return "Core Breach! Evacuate Ship!"

If an exception is thrown using this constructor, getMessage should return the value that was used as an argument to the constructor.arrow_forwardUsing Java Define a Rubric class that extends the GradedActivity class shown below.

- Defined Exception Handling Exception Handling is used to overcome exceptions that take place during programs’ execution in a systematic manner. For instance, dividing a number by ‘0’ is a mathematical error (not defined). As you learned in class, you can use exception handling to overcome such operations. If you write a code without using exception handling, then the output of division by zero will be shown as infinity which cannot be further processed. Consider the following code: float Division(float num, float den) {return (num / den);} int main() { float numerator = 12.5; float denominator = 0; float result; result = Division(numerator, denominator); cout << "The quotient of 12.5/0 is " << result << endl; }arrow_forwarda) Write a method in java that searches a numeric array for a specified value. The method should return the subscript of the element containing the value if it is found in the array.
