Create a class named Account that contains an integer field for an account number and a double field for an account balance. The class contains a constructor that requires an account number and sets the balance to 0.0. Include a set() method for the balance, a get() method for the account number, and a get() method for the account balance. Create two subclasses named Checking and Savings. Within the Checking class, the get() method should display the String "Checking Account Information", the account number, and the balance. Within the Savings class, add a field to hold the interest rate, and require the Savings constructor to accept an argument for the value of the interest rate. The Savings get() method displays the String "Savings Account Information", the account number, the balance, and the interest.
