java When we create an object of a class, the object's instance variables are automatically initialized with its default values without us writing code in any constructor. Choose one of the options: True False

Java:

1. RetailItem Class Write a class named Retailltem that holds data about an item in a retail store. The class should have the following fields: • description. It is a String object that holds a brief description of the item. • unitsOnHand. It is an int variable that holds the number of units currently in inventory. • price. It is a double that holds the item's retail price. Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them. Units On Hold Description Designer Jeans Jacket Price 40 34.95 12 59.95 Shirt 20 24.95

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)…

in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…

True or False ___(10) You only need to override methods you need in an interface while ignoring other methods that you don’t use. ___(11) In Java the expression instanceof returns a boolean value. ___(12) One of the most important benefit of using inheritance in Java is the reuse of code
