Overview

This project involves creating a program to manage and display information about monetary values. The main components of the project include classes representing different denominations of money (e.g., bills, coins), a graphical user interface (myGUI) for user interaction, and handlers (ButtonClickListener and PrintClickListener) to process input and output.

Files

1. Bill.java

• Represents a bill with a specified dollar amount. Extends the Money class.

2. ButtonClickListener.java

• Handles button click events in the GUI.
• Processes user input and interacts with other classes (SaveMoney, SaveDate, ReadDate, ReadMoney).

3. Coin.java

• Represents a coin with a specified value.
• Extends the Money class.

4. Dime.java

• Represents a dime coin.
• Extends the Coin class.

5. Main.java

• Main class to start the program by initiating the GUI (myGUI).

6. Money.java

• Represents a generic monetary value.
• Implements Serializable for object serialization.

7. myGUI.java

• GUI class with functionalities for user input and output.
• Utilizes ButtonClickListener and PrintClickListener.

8. Nickel.java

• Represents a nickel coin.
• Extends the Coin class.

9. PrintClickListener.java

• Handles the "Save to ledger.txt" button click event.
• Initiates the PrintLedger class to save the content of a TextArea to a file.

10. PrintLedger.java

• Saves the content of a TextArea to a file named "ledger.txt".

11. Quarter.java

• Represents a quarter coin.
• Extends the Coin class.

12. ReadDate.java

• Reads a Date object from the "date.out" file.
• Displays the date in the GUI.

13. ReadMoney.java

• Reads monetary information from the "money.out" file.
• Displays the total amount of money and the quantity of each denomination in the GUI.

14. SaveDate.java

• Saves the current date to the "date.out" file.

15. SaveMoney.java

• Saves monetary information to the "money.out" file.
• Processes user input from the GUI.

How to Run

1. Execute the main method in the Main.java class to initiate the GUI.

2. Enter a monetary value in the provided text field and click the "Count change" button.

3. Optionally, click the "Save to ledger.txt" button to save the displayed information to a file.

Usage

• The GUI allows users to input monetary values and view the corresponding breakdown of bills and coins.

• The program uses serialization to save and load monetary information and the current date.
