What are the advantages of making use of the exception handling method?

f18 In c++

In C++  You have a class called Fraction, which uses the heap. The constructor for the class is declared as: Fraction::Fraction(); Implement an exception handling design in the parameterized constructor to catch zeros in the denominator. Show the new exception class you will need to put in the header (specification) file. Show the definition for your parameterized constructor that throws the exception if the denominator is zero. Finally, show how to use the try-catch statement in the driver program when instatiating a new paramerized Fraction object. You do not need to show entire programs, only the requested lines of source code

Briefly explain floating-point exception

In a Java application, how many different sorts of exceptions may occur?

Please can you answer these three questions

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?

JAVA CODE   Unchecked exceptions are exceptions that are usually the result of a mistake and we aren't expected to handle, while checked exceptions are exceptions that we reasonably expect to occur that we should handle whenever possible. Name one type of unchecked exception and one type of checked exception, and give an example of situations that might cause those exceptions to be thrown.

Suppose a catch handler with a precise match to an exception object type is available. Under what circumstances might a different handler be executed for exception objects of that type?
