a class date, each object is a value represented the day in the year in form year,month,day.Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values in case no initializes are provided.Provide Public member functions for each of the following operations: set the day, set the month,set the year, set the date,print the date in the form yyyy,mm,dd , increment the datebyoneday, increment the dateby one month, compare two datesfor equality, and final determine if one dateis “less than” (comes before) another date.Include any additional operations that you think would be useful for your class.Design,implement, and test your class.

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks:                                                                        Bonds: Purchase date (Date)                                                   Purchase date (Date) Purchase price (double)…

a) Illustrate the comparison between Scenario-based Modeling vs. Class-based Modelling.

1- Design a class named Rectangle to represent a Rectangle. The class contains: • three variables integer data field named height, integer data filed named width and integer data filed named length. The default values are 1 for height, length, and width are 1.0 for each of them respectively. • A no-arg constructor that creates a default Rectangle. • A constructor that creates a Rectangle with the specified height, length and width. • A method named getVolume() that returns the volume of this Rectangle. (Volume = height * width * length) %3! 2- Write a test program called Test Rectangle that: • Creates two Rectangle objects: one object with height 11, length 5, and width 7, the other object with height 10, length 2 and width 6 • Display the volume of each Rectangle object.

Name the operator that you can use to check whether an object is an instance of a specified class

Create a Class called Transaction with: instance variables: stock - your stock class type - char -> b or s (buy/sell) quantity - can be fractional price - buy/sell price when - LocalDate   constructors: constructor with parameters for stock, type and quantity. - sets the price from the stock price instance variable - sets when from LocalDate   getters and setters for each instance variable
