Program Description Answer
New objects are created by invoking the constructor.
Hence, the given statement is “True”.
Expert Solution & Answer
Explanation of Solution
Objects:
- An object is a software entity that contains both data and procedures.
- It contains the collection of related information and the set of operations to operate the information.
- The data present in an object is called as object’s data attributes.
- The object’s data attribute is the variable that refers to the data.
- The object performs a procedure that is known as methods.
- An object said to be instance of the class and the new objects are created from the class by invoking the constructor.

Your task is to create a BankAccount class.
Class name
BankAccount
Attributes
_balance
float
_pin
integer
Methods
init ()
get_pin()
check pin ()
deposit ()
withdraw ()
get_balance ()
The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The
pin should be generated randomly when the account object is created. The initial balance should
be 0.
get_pin () should return the pin.
check_pin (pin) should check the argument against the saved pin and return True if it
matches, False if it does not.
deposit (amount) should receive the amount as the argument, add the amount to the account
and return the new balance.
withraw (amount) should check if the amount can be withdrawn (not more than is in
the account), If so, remove the argument amount from the account and return the new balance if
the transaction was successful. Return False if it was not.
get_balance () should return the current balance.…

- 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 data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…arrow_forward
