In Java programming, when is it appropriate to use user-defined exceptions vs. built-in exceptions?

f18 In c++

When someone "overloads" a function or an operator, what precisely does this imply? What are some of the benefits associated with it? How can the user be protected from making mistakes by using the many different exception handling mechanisms that might be programmed?

Describe the purpose and use of the "try-catch" block in exception handling.

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 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.

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.

Which is the Parent class for all exceptions? (1) std::bad_exception(2) std::logic_error(3) std::exception(4) std::runtime_error

What kind of exceptions are captured during the compilation process of the program?
