I am making a virtual keyboard in java eclipse$/$scene builder and am attempting to get letter and number keys to play audio of what key is pressed. I.e$.$ when you press A$,$ it plays a sound file saying $"$A$".$ Attached is a part of the code I have currently have, using the A button as an example. I already have and am planning on using wav audio files. Any help to get this working would be much appreciated.

import java.io$.$FileWriter;

import java.io$.$IOException;

import javafx.event.ActionEvent;

import javafx.fxml$.$FXML;

import javafx.scene.control.Button;

import javafx.scene.control.TextArea;

import javafx.scene.control.ToggleButton;

import javafx.scene.shape.Circle;

public class VirtualKeyboardController $\{$

private boolean shiftPressedLeft $=$ false;

private boolean shiftPressedRight $=$ false;

private boolean capsLockOn $=$ false;

@FXML

private TextArea textArea;
