For this fifth Critical Thinking assignment you will modify an existing app that tracks business expenses. Download the existing app in the Modules Tab underneath the assignment and explore the application. There are two inner classes:ExpenseItem, which defines constants used in mapping the Expense data to the database, andHelper. You should see that theExpenseclass is a simple POJO with properties of amount, description, and expenseDate.
ADAOis an excellent and widely-used design pattern where the code to access a data source is encapsulated within a single class.
