(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). Use java swing to write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Some sample screenshots are shown below:
(Member Object Destructors) Write a program illustrating that member object destructorsare called for only those member objects that were constructed before an exception occurred.

- (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.

- (Package Inheritance Hierarchy) Use the Package inheritance hierarchy created inExercise 19.9 to create a program that displays the address information and calculates the shippingcosts for several Packages. The program should contain a vector of Package pointers to objects ofclasses TwoDayPackage and OvernightPackage. Loop through the vector to process the Packagespolymorphically. For each Package, invoke get functions to obtain the address information of thesender and the recipient, then print the two addresses as they would appear on mailing labels. Also,call each Package’s calculateCost member function and print the result. Keep track of the totalshipping cost for all Packages in the vector, and display this total when the loop terminates.arrow_forward(Rational Class) 1. Create a class called Rational (separate the files as shown in the chapter) for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private data of the class-the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default values in case no initializers are provided and should store the fraction in reduced form. For example, the fraction 2/4 would be stored in the object as 1 in the numerator and 2 in the denominator. Provide public member functions that perform each of the following tasks: Make an overloaded operator of the + symbol for the add method - Adds two Rational numbers. The result should be stored in reduced form. Make an overloaded operator of the - symbol for the subtract method - Subtracts two Rational numbers. Store the result in reduced form. Make an overloaded operator of the *…arrow_forward(Rectangle Class) Create a class Rectangle with attributes lengthand width, each of which defaults to 1.

- (The MyDate class) Design a class named MyDate. The class contains: The data fields year, month, and day that represent a date. month is 0-based, i.e., 0 is for January. A no-arg constructor that creates a MyDate object for the current date. A constructor that constructs a MyDate object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. A constructor that constructs a MyDate object with the specified year, month, and day. Three getter methods for the data fields year, month, and day, respectively. A method named setDate(long elapsedTime) that sets a new date for the object using the elapsed time. Draw the UML diagram for the class and then implement the class. Write a test program that creates two MyDate objects (using new MyDate() and new MyDate(34355555133101L)) and displays their year, month, and day. (Hint: The first two constructors will extract the year, month, and day from the elapsed time.
