5. CODE IN PYTHON Create a BankAccount class which has an __init__ method which accepts an account name and starting balance to store as instance fields. The class should also have a method to deposit money, a method to withdraw money, and a method called "get_balance" which returns a string of the format "{account_name} has a balance of {balance}" (do not print this out from within the class, just return the string). In the same file, create an instance of the BankAccount class with a hardcoded name and starting balance. Deposit any amount to the account and withdraw any amount from the account (both can be hardcoded) and then print the result of calling the get_balance method on the instance.
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
Using python write a program that contains 1. a class named information that has the following hidden data attributes ( write appropriate accessor and mutator methods): name address age phone 2. using main() function create an instance of information that holds your information 3. following is the output after this program executes : my information: Name: Your name( first and last): address: 1111 my street. age: 24. phone Number: 555-555-1234 write code without comments
The class contains one constructor: public Account (double initBal, String owner, long number) which initializes the instance variables. 1. Overload the constructor as follows: public Account (double initBal, String owner) - initializes the balance and owner as specified; randomly generates the account number. public Account (String owner) - initializes the owner as specified; sets the initial balance to 0 and randomly generates the account number. public Account () - initializes the owner with empty string name; sets the initial balance to 0 and randomly generates the account number. 2. Overload the withdraw method that also takes a fee parameter and deducts that fee from the account. 3. Write a driver program that invokes all four versions of the constructors and two versions of the withdraw methods. Think about how the compiler can tell which method is invoked.
