Modify the MilTime class given under Final exam module. The class should implement the following exceptions: BadHour Throw when an invalid hour (< 0 or > 2359) is passed to the class. BadSeconds Throw when an invalid number of seconds (<0 or > 59) is passed to the class. Demonstrate the class in a driver program. Demo in the main function.
the file:
// MillTIme.cpp//#include "stdafx.h"#include <iostream>using namespace std;class Time{protected: int hour; int min; int sec;public: Time(int h, int m, int s) { hour = h; min = m; sec = s; }
int getHour() { return hour; }
int getMin() { return min; }
int getSec() { return sec; }};
class MilTime : public Time{private: int milHours; int milSeconds;public: MilTime(int h = 0, int s = 0) : Time(0, 0, s) { if (h < 0 || h > 2359) { cout << "Hours must be in the range 0 - 2359.\n"; milHours = h;…
Exceptions in Java
Write a program that accepts two integers X and Y. After, divide X by Y. If an exception occurs, print the following:
If divided by zero, print "Division by zero is illegal."
Print the result of the division if there is no error.
Inputs
1. X
2. Y
Sample Output
Enter X: 1
Enter Y: 0
Division by zero is illegal.

An interface can contain defined constants as well as method headings or instead of method headings. When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. Can you have a static method in a nonstatic inner class?arrow_forward
