WRITE THE CODE IN JAVA FOR AN UPVOTE

- Using the class as a base class, complete the two classes called and Both classes should inherit the Account class. - A object, in addition to the attributes of an object, should have: 1) An interest rate private variable of type double named 2) A method named . This method does not take any parameters, but it returns the interest rate on the account. 3) A method named applyInterest(). This method applies the interest rate to the account's balance and increases it. For example, if the interest rate is 0.4 and the balance is 1000 , calling this method should update the balance to 1400 . This method does not take any parameters and does not return anything. - A object, in addition to the attributes of an object, should have: 1) An overdraft limit private variable of type integer named 2) A method which returns the overdraft limit of the account. The method does not take any parameters but it return the overdraft limit. 3) A method to update the overdraft limit on the account. This method takes an integer, but it does not return anything. Hints: - Note that the balance of an account may only be updated through the - The and classes should not need to be modified at all. - Test your code using the class
