It consists of 3 text fields and 2 JCalendar that require the customer\u2019s information to be added to the database.<\/p>\n<p>2. Then, we add an \u201cADD\u201d button, which inserts data into the database from the text fields.<\/p>\n<p>Now in the retrieval part, we will apply the following:<\/p>\n<p>1. Build a connection first with the database using the Connection object.<\/p>\n<p>2. Inject the query that stores table data in ResultSet.<\/p>\n<p>3. Finally, send data to Jtable.<\/p>\n<p>4. Calculate the total bill by getting the number of days of stay from dates entered by the user &amp; multiplying it by 1000, and finally adding the result to the room-service charge.<\/p>\n<p>5. This information also gets stored in the database.<\/p>\n<h2><strong>Output<\/strong><\/h2>\n<h3><strong>Main Interface<\/strong><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-18260 size-full alignnone\" src=\"https:\/\/rudelabs.ai\/blogs\/wp-content\/uploads\/2022\/11\/c-users-vaibhu-appdata-local-microsoft-windows-in-2.webp\" alt=\"Hotel Billing System In Java\" width=\"799\" height=\"491\" \/><\/p>\n<h2><strong>Conclusion<\/strong><\/h2>\n<p>We have successfully managed to make a project of a Hotel Billing System In Java to generate bills of hotel rooms with the Swing module used for GUI.
