Using eclipse 4 classes must be defined Paragraph Styles Problem (25 points) First American Bank provides both normal bank services like checking accounts and mortgages to its customers. Each customer who uses checking services has a checking account. Each customer who gets a mortgage loan from the bank has a mortgage account The bank executives ask a team of software analysts to develop a system to manage its customers' bank accounts Section A: Define an abstract Java class named "BankAccount" in a package named BANKACCOUNTS, This class has three attributes: (1) Acount number: an integer of 10 digits, defined as protected (2) Account type: String (e.g.: "CHECKING versus "MORTGAGE"), defined as . protected (3) Customers full name: String, defined as protected Class BankAccount definition provides . a default constructor . get-methods and set-methods for the variable attributes, . a public method, named "displayAccountData0", that prints out the following pieces of data: account number, account type, and customer's full name in only one line. Section B: Define a Java class named CheckingAccount in the same package, BANKACCOUNTS that extends the class BankAccount. Class CheckingAccount has only one attribute: checking balance, that is defined as private. . Class CheckingAccount definition provides: 19 f10 112 break
