Factory pattern is one of the most used design patterns in Java. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object. In Factory pattern, we create object without exposing the creation logic to the client and refer to newly created object using a common interface.

We have already written C++ Program to solve Simple Banking Problem, Now let us solve this using Java. In this program we are using two classes, bankInternal and Bank which carry out the required operations.
bankInternal has a constructor which gathers all the required information like account number, initial balance of the account. Deposit method is used to deposit money in the account and withdraw method is used to withdraw money from the account, if there is sufficient balance in the account.
Bank contains the main method which creates object to the bankInternal class. We have created object named myObj and calling only deposit() and withdraw() methods as we don’t need to call bankInternal() because it is a constructor and it will be called once the object is created.
