A pedometer treats walking 2,000 steps as walking 1 mile. Write a stepsTOMiles() method that takes the number of steps as an integer parameter and returns the miles walked as a double. The stepsToMiles() method throws an Exception object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main() method that reads the number of steps from a user, calls the steps ToMiles() method, and outputs the returned value from the steps ToMiles() method. Use a try-catch block to catch any Exception object thrown by the stepsToMiles() method and output the exception message. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); Ex: If the input of the program is: 5345 the output of the program is: 2.67 Ex: If the input of the program is: -3850 the output of the program is: Exception: Negative step count entered.

Write a Month class that holds information about the month. Write exception classes for the following error conditions:• A number less than 1 or greater than 12 is given for the month number.• An invalid string is given for the name of the month.Modify the Month class so that it throws the appropriate exception when either of these errors occurs. Demonstrate the classes in a program.

X1155: Throwing an Exception The method below takes in a String parameter representing a username. It should throw an Exception if the username is less than 3 characters long. The method correctly throws the exception, but something is still missing. Fix the problem. Your Answer: Feedback 1 public String validateUser (String userName) 2|{ 3 45 6 7 8|} 9 if (userName.length() < 3) { throw new Exception("userName is too short"); } return userName; Check my answer!

Write an application that displays a series of at least eight student ID numbers (that you have stored in an array) and asks the user to enter a test letter grade for the student. Create an Exception class named GradeException that contains a static public array of valid grade letters (A, B, C, D, F, and I) that you can use to determine whether a grade entered from the application is valid. In your application, throw a GradeException if the user does not enter a valid letter grade. Catch the GradeException, and then display the message Invalid grade. In addition, store an I (for Incomplete) for any student for whom an exception is caught. At the end of the application, display all the student IDs and grades.   import java.util.*; public class TestGrade {     public static void main(String args[]) throws Exception {         Scanner input = new Scanner(System.in);         int[] ids = {1234, 1245, 1267, 1278, 2345,                      1256, 3456, 3478, 4567, 5678                     };…

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;…
