The objective of the Finance Tracker application is to provide users with a tool for managing their personal finances efficiently. The application should allow users to track their income, expenses, budgets, and generate reports to analyze their financial activities.
· UserAuthentication: Users should be able to create accounts and log in securely to accesstheir financial data.
· TransactionManagement: Users should be able to add, edit, and categorize transactions suchas income, expenses, transfers, etc.
· BudgetTracking: Users should be able to set up monthly budgets for different expensecategories and track their spending against these budgets.
· Reporting:The application should provide various reports such as monthly expensesummaries, income vs. expenses, budget adherence, etc.
· DataPersistence: All financial data entered by the user should be securely storedand retrievable across sessions.
· Security:The application should implement robust security measures to protect users'financial information.
Implementation Details:
· Object-OrientedDesign:
Classes: User,Transaction, Category, Budget, Report, etc.
Utilize inheritance andcomposition where appropriate to model relationships between entities.
· AbstractClasses and Interfaces:
Abstract classes:Transaction (with subclasses for different types like IncomeTransaction,ExpenseTransaction), Report.
Interfaces:DataPersistence (for defining methods related to data storage), Security (fordefining methods related to authentication and authorization). Use existinglibraries to apply security.
· Threads:
Use threads forbackground tasks such as generating reports asynchronously to avoid blockingthe main UI thread.
· ExceptionHandling:
Implement exceptionhandling for scenarios like invalid input during transaction entry, databaseerrors during data persistence, authentication failures, etc.
