Personal Finance Manager

This is a simple console-based application for managing personal finances. It allows users to add transactions, view all transactions, view transactions within a specific period, and view transactions from a specific date.

Features

• Add transaction: Allows the user to input a date (in DD.MM.YYYY format) and the amount spent for that transaction. This data is stored in a text file.
• Show transactions: Displays a history of all recorded transactions with their dates and amounts.
• Show transactions by period: Prompts the user for a start and end date (in DD.MM.YYYY format) and displays all transactions within that date range.
• Show transactions by date: Asks the user for a specific date (in DD.MM.YYYY format) and shows all transactions recorded on or after that date.
• Exit: Terminates the application.

How to Run

1. Save the provided Java code into the following directory structure:

   personalFinanceManager/src/
   

   Ensure you have the following files within this structure:
   • ConsoleInterface.java
   • Main.java
   • TransactionReader.java
   • TransactionWriter.java
2. Create a directory named data inside the personalFinanceManager directory:

   personalFinanceManager/data/
   

3. Inside the data directory, create an empty text file named transactions.txt:

   personalFinanceManager/data/transactions.txt
   

4. Compile the Java source files. Open a terminal or command prompt, navigate to the personalFinanceManager directory, and run the following command:

   javac src/*.java

5. Run the application from the personalFinanceManager/src directory:

   java personalFinanceManager.src.Main

   Alternatively, if your classpath is correctly configured, you might be able to run it from the personalFinanceManager directory:

   java personalFinanceManager.src.ConsoleInterface

Code Structure

The project consists of the following Java classes:

• ConsoleInterface.java: Handles the console-based user interface, displaying options and taking user input.
• Main.java: The entry point of the application, which creates and launches the ConsoleInterface.
• TransactionReader.java: Responsible for reading transaction data from the transactions.txt file and displaying it based on different criteria (all, by period, by date).
• TransactionWriter.java: Handles writing new transaction data (date and amount) to the transactions.txt file.

• TransactionWriter.java: Handles writing new transaction data (date and amount) to the transactions.txt file.

Data Storage

Transaction data is stored in a simple text file named transactions.txt located in the personalFinanceManager/data/ directory. Each transaction occupies two lines: the first line contains the date in the format date: DD.MM.YYYY, and the second line contains the amount spent in the format money: amount.

Notes

• The application relies on user input in the specified format (DD.MM.YYYY for dates). Incorrect input might lead to errors.
• The data is stored in a plain text file, which is suitable for simple use cases but might not be robust for handling large amounts of data or concurrent access.
