Task
Write a JAVA class named Account to represent an account that you may find at a bank. Accounts have a balance and an annual interest rate. Include attributes in the Account class to reflect these.
Write getters for both attributes and a setter for only the annual interest rate. Think about how real bank accounts work, you change your balance by withdrawing and depositing money, not just by telling the banker how much you want to change it to.
Include a constructor with parameters used to assign values to both attributes.
Users should be able to withdraw money from an Account, deposit money into an Account, find monthly interest rate, and find monthy interest. Include methods for each of these actions. More details on them below.
withdraw method
This method simulates withdrawing money from the Account. It should not return a value and take the amount to withdraw as a parameter and reduce the balance by this amount.
deposit method
This method simulates depositing money into the Account. It should not return a value and take the amount to deposit as a parameter and increase the balance by this amount.
getMonthlyInterestRate method
This method calculates and returns the monthly interest rate. The interest rate that you have as an attribute is the annual interest rate. To "covert" the annual rate to the monthly rate, simply divide the annual rate by 12.
getMonthlyInterest method
This method calculates and returns the interest gained for the month. That is, take the balance and multiply it by the monthly interest rate.

Please answer in python quickly Below is code that defines a Quadrilateral class (a shape with four sides), which has four floating point instance variables that correspond to the four side lengths: import math class Quadrilateral: def __init__(self,a,b,c,d): self.a = a self.b = b self.c = c self.d = d def perimeter(self): return self.a + self.b + self.c + self.d def area(self): print("Not enough information") def __lt__(self, other): return self.perimeter() < other.perimeter() Define a Rectangle class that inherits from Quadrilateral, with the following methods: __init__(self, length, width): Override the __init__ method so that the Rectangle constructor only takes in two floating point numbers.
