Question
Chapter 22, Problem 22.24E
Program Plan Intro
- To create a class Test_des whose objects will invoke the constructors.
- To define the destructors to print a message when they are called.
- To create objects of this class in a test program called throw an exception.
Summary Introduction- The program demonstrates that before any exception is thrown from a block, the destructors for all the constructed objects are called first.
Program Description- The purpose of the program is to demonstrate that before any exception is thrown from a block, the destructors for all the constructed objects are called first.

(Local Variable Destructors) Write a program illustrating that all destructors for objectsconstructed in a block are called before an exception is thrown from that block.
(Creating Custom Exception Class) Write a Password class that stores a password string. Passwords must contain at least seven alpha-numeric characters, with at least one letter and one digit. Also write an InvalidPasswordException class that extends Exception. The Password constructor should throw an InvalidPasswordException, which should report an appropriate message based on a given string (e.g. if the string contains no digits, the exception should report this fact). Write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Please teach and help me how to deisgn the program based on the two files given .Some sample screenshots are shown below:
InvalidPasswordException.java
public class InvalidPasswordException extends Exception{ public InvalidPasswordException (String errMsg){ super(errMsg); } }
Password.java
public class Password {private String passwordstr;

(Member Object Destructors) Write a program illustrating that member object destructorsare called for only those member objects that were constructed before an exception occurred.

Now suppose that the exception handler itself throwsthe same exception. Does this create infinite recursion? Write a program to check your observation.arrow_forward(Replace strings) Write the following function that replaces the occurrence of a substring old_substring with a new substring new_substring in the string s. The function returns true if string s is changed, and otherwise, it returns false. bool replace_strings (string& s, const string& old_string, const string& new_string) Write a test program that prompts the user to enter three strings, i.e., s, old string, and new_string, and display the replaced string.arrow_forward

- (Rectangle Class) Create class Rectangle. The class has attributes length and width, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area of the rectangle. It has properties for both length and width. The set accessors should verify that length and width are each floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Rectangle.

The airplane has 13 rows, with six seats in each row. Rows 1 and 2 are first class, rows 3 through 7 are business class, and rows 8 through 13 are economy class. Use two parallel arrays: a one-dimensional array to store the row number of the seats (Row #) a two-dimensional array of 13 rows and 6 columns to store the seat assignments (*) and seat letters (A-F) Your program must prompt the user to enter the following information: Reserve a seat (Yes (Y/y) or No (N/n)) Assign ticket type (first class (F/f), business class (B/b), or economy class (E/e)) Select desired seat (1-13 and A-F) Your program must contain at least the following functions: a function to initialize the seat plan. a function to show the seat assignments. a function to show the menu to assign a seat. a function to assign and select your desired seat. a function for each ticket type that determines if a seat…arrow_forward
