Suppose you are employed by a advertisement agency to design a system to send advertisements in different languages and to different modes such as sms, email, in-mail, cable-tv, etc. (more can be added later or).

The process of sending an advertisement is always the same irrespective of the language or the mode of the advertisement. The process is as follows:

1. The text of the advertisement is received as text

2. The text is then translated into a desired language.

3. The translation depends upon the mode of advertisement

4. The translated text is then proof-read for consistency

5. And then the text is advertised on the required mode

Your task is the following:

• Identify the design pattern that can be used over here

• Justify your choice

• Make a class diagram (using UML Notation)

• Implement the classes in JAVA

• Test your implementation

Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee.

(The Person, Student, Employee, Faculty, and Staff classes)

A person has a name, address, phone number, and email address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person’s name.

Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.

Write a java Program considering the following scenario.

•Mobile is an Object that contains basic functionalities including Calling & Receiving a call & Messaging. The Mobile has certain features including Processor, internal memory, single or dual SIM, weight. The IMEI number is only used for identifying the device.

•In case of Samsung, the Android version, Camera Specs and playing FM Radio, capturing photos.

•iPhone may have an ios version, Music Player, Camera.

•Any of these mobile phones can be used to make a call or send a text message.

Create a class named MusicalComposition that contains fields for title, composer, and year

written. Include a constructor that requires all three values and an appropriate display function.

The child class NationalAnthem contains an additional field that holds the name of the

anthem’s nation. The child class constructor requires a value for this additional field. The child

class also contains a display function. Write a main() function in class MusicDemo that

instantiates objects of each class and demonstrates that the functions work correctly.

Create an Investment class that contains fields to hold the initial value of an investment, the

current value, the profit (calculated as the difference between current value and initial value),

and the percent profit (the profit divided by the initial value). Include a constructor that requires

initial and current values and a display function. Create a House class that includes fields for

street address and square feet, a constructor that requires values for both fields, and a display

function. Create a HouseThatIsAnInvestment class that inherits from Investment and House. It

includes a constructor and a display function that calls the display functions of the parents
