1. Create a GUI java application using the Swing toolkit that reads from an existing table in a database of Client records.
2. write a Client class that Includes getter and setter methods for the instance variables and a toString method for the purpose of displaying the object's data.
3. Display a Clients data in a combo box from a database table.
4. When the user selects a Client move the client's name into a non-editable textbox and the client number into a non-editable textbox and the client wallet into an editable textbox.
5. Add an Add Client button. When the user clicks the "Add Client" button the application will validate the input data and only add valid data to the database table and the combo box, otherwise an appropriate error message will be displayed.
6. Add a Delete Client button. When the user clicks the "Delete Client" button the application will remove the selected record from the combo box and remove the corresponding record from the database table, otherwise an appropriate error message will be displayed.
7. Add an Update Client button. When the user clicks the "Update Client" button the application will accept a new wallet value for the selected client and update the combo box data and the corresponding record in the database table, otherwise an appropriate error message will be displayed.
8. Finally add a Clear Text button. When the user clicks the "Clear Text" button the application will remove text from all the text field boxes in the form.
