AudioClip is abstract; cannot be instantiated.

Here's Home.java I put some spacing around the part that gets an error:

package com.teamtreehouse.pomodoro.controllers;

import com.teamtreehouse.pomodoro.model.Attempt; import com.teamtreehouse.pomodoro.model.AttemptKind; import javafx.animation.Animation; import javafx.animation.KeyFrame; import javafx.animation.Timeline; import javafx.beans.property.SimpleStringProperty; import javafx.beans.property.StringProperty; import javafx.event.ActionEvent; import javafx.fxml.FXML; import javafx.scene.control.Label; import javafx.scene.control.TextArea; import javafx.scene.control.TextField; import javafx.scene.layout.VBox; import javafx.util.Duration;

import java.applet.AudioClip;

public class Home { private final AudioClip mApplause; @FXML private VBox container;

@FXML
private Label title;

@FXML
private TextArea message;

private Attempt mCurrentAttempt;
private StringProperty mTimerText;
private Timeline mTimeline;

public Home() {
    mTimerText = new SimpleStringProperty();
    setTimerText(0);



    mApplause = new

AudioClip(getClass().getResource("/sounds/applause.mp3").toExternalForm());

}

public String getTimerText() {
    return mTimerText.get();
}

public StringProperty timerTextProperty() {
    return mTimerText;
}

public void setTimerText(String timerText) {
    mTimerText.set(timerText);
}

public void setTimerText(int remainingSeconds) {
    int minutes = remainingSeconds / 60;
    int seconds = remainingSeconds % 60;
    setTimerText(String.format("%02d:%02d", minutes, seconds));
}

private void prepareAttempt(AttemptKind kind) {
    reset();
    mCurrentAttempt = new Attempt("", kind);
    addAttemptStyle(kind);
    title.setText(kind.getDisplayName());
    setTimerText(mCurrentAttempt.getRemainingSeconds());
    mTimeline = new Timeline();
    mTimeline.setCycleCount(kind.getTotalSeconds());
    mTimeline.getKeyFrames().add(new KeyFrame(Duration.seconds(1), e -> {
        mCurrentAttempt.tick();
        setTimerText(mCurrentAttempt.getRemainingSeconds());
    }));
    mTimeline.setOnFinished(e -> {
        saveCurrentAttempt();
        prepareAttempt(mCurrentAttempt.getKind() == AttemptKind.FOCUS ?
                        AttemptKind.BREAK : AttemptKind.FOCUS);
        mApplause.play();
    });
}

private void saveCurrentAttempt() {
    mCurrentAttempt.setMessage(message.getText());
    mCurrentAttempt.save();
}

private void reset() {
    clearAttemptStyles();
    if(mTimeline != null && mTimeline.getStatus() == Animation.Status.RUNNING) {
        mTimeline.stop();
    }
}

public void playTimer() {
    mTimeline.play();
}

public void pauseTimer() {
    mTimeline.stop();
}

private void addAttemptStyle(AttemptKind kind) {
    container.getStyleClass().add(kind.toString().toLowerCase());
}

private void clearAttemptStyles() {
    for(AttemptKind kind : AttemptKind.values()) {
        container.getStyleClass().remove(kind.toString().toLowerCase());
    }
}

public void DEBUG(ActionEvent actionEvent) {
    System.out.println("Hi!");
}

public void handleRestart(ActionEvent actionEvent) {
    prepareAttempt(AttemptKind.FOCUS);
    playTimer();
}

}

hi Binyamin Friedman , you have imported the wrong AudioClip so remove this line import java.applet.AudioClip;

it should be 

import javafx.scene.media.AudioClip;
