In Java, please comment and comment with output please This programming assignment involves learning about some of the common exceptions that occur in Java programs. Consider the following exception types: NullPointerException ArrayIndexOutOfBoundsException ClassCastException IllegalArgumentException Research what each exception type means and the conditions under which each occurs (i.e., is thrown). Write programs that demonstrate each type of exception being thrown (one program per exception) and provide a screen capture of the output. Name your programs as follows: NullPointerExceptionThrown, etc. Then, write a program that catches each type of thrown exception and display an error message indicating some of the details as to what that exception is. Write one program per type of exception. Name your programs as follows: NullPointerExceptionCatch, etc.

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…
