Design and implement a program that reads an integer value (let's say x) as a command line argument. Further, the program reads a series of 'x' integer values from the user and prints their average. Read each input value as a String, and then attempt to convert it to an integer. If this process throws an exception (meaning that the input is not a valid number), print the appropriate error message and prompt for the number again. Continue reading values until 'x' valid integers have been entered. Hint: Think of all possible errors that this process could cause, and incorporate appropriate exception handlers in your programs. Note: You cannot use the root/general exception class 'Exception'

I need to know how to do this in python: Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info." Ex: If the input is: 35 the output is: Fat burning heart rate for a 35 year-old: 129.5 bpm If the input is: 17 the output is: Invalid age. Could not calculate heart rate info.

This is the question - 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. Code I was given, I will attach a screenshot of the errors-  public class GradeException extends Exception {     public GradeException(String string) {     } }   import java.util.*; public class TestGrade {    public static void main(String args[]) throws…

Write a program that uses an exception class called StringTooLongException, designed to be thrown when a string is discovered that has too many characters in it.  You will create the StringTooLongException.java file first based on the information presented in the chapter. In the StringError.java program, read strings from the user until the user enters "DONE". If a string is entered that has too many characters (say 10), throw the exception. StringError should catch and handle the exception if it is thrown. Handle the exception by printing an appropriate message, and then continue processing more strings.
