Importing .csv or .txt Files to Display High Scores in JavaFX TableView

Creating a high score menu is an exciting feature for many gaming applications. However, it can be challenging to integrate data sources, especially when you want to display high scores recorded in .csv or .txt files. In this guide, we will guide you step by step on how to efficiently import these files into a TableView using JavaFX and SceneBuilder.

Understanding the Problem

When designing a high score menu, the primary goal is to display the scores stored in .csv or .txt files. The challenge often arises when developers try to read data from these files and display it in a user-friendly format within a JavaFX application.

In our case, a developer faced difficulties in importing high score data using the traditional file read methods. The solution will involve updating their code to correctly read from the file and populate the TableView in SceneBuilder.

Solution Overview

To successfully fetch data from .csv or .txt files and display it on the TableView, the following steps outline the complete process:

Reading the File: Utilize Java’s Scanner class to open and read the contents of the file.

Parsing the Data: Split each line of the file to gather the individual data points (e.g., number, name, and score).

Populating the ObservableList: Store the parsed data into an ObservableList that the TableView listens to for changes.

Binding the List to TableView: Finally, bind the list to the TableView to ensure that it displays the latest data.

Step 1: Reading the File

Here's how to use the Scanner class to read the file containing your high scores:

Step 3: Populating the ObservableList

Create an empty ObservableList to hold your high score entries and populate it within a method called initList():

Step 4: Binding the List to TableView

In the initialize method of your controller, call initList() and bind the populated list to the TableView:

Conclusion

Integrating a file-based scoring system into your JavaFX application can seem daunting at first, but breaking the task down into smaller parts will make the process much easier. By following the steps outlined in this guide, you will be able to successfully import .csv or .txt files to display high scores in your application’s TableView.

Now, you can focus on enhancing your high score menu even further by adding features like sorting, ranking, or even personalized player statistics. Embrace the challenge and enjoy coding!
