Question

What Applet method can you use to play a sound file?

Short answer

Answer: The method used in an Applet to play a sound file is the 'play' method, which has the following signature: `public void play(URL url)`. It takes a URL as an argument representing the location of the sound file to be played. An example of its usage is as follows: ```java import java.applet.*; import java.net.*; public class SoundApplet extends Applet { public void init() { try { URL soundFile = new URL(getCodeBase(), "soundFile.wav"); play(soundFile); } catch (MalformedURLException e) { e.printStackTrace(); } } } ``` In this example, the 'play' method is called in the 'init()' method of the applet, automatically playing the sound file 'soundFile.wav' located in the same directory as the applet's code.

Step-by-step solution

Review Applet Class Methods

To find the appropriate method, look up the available methods for the java.applet.Applet class in the Java documentation. We are looking for a method specifically designed for playing sound files.

Identify the Applet Sound Playing Method

Among the available methods, the 'play' method is the one dedicated to playing sound files. The Applet class provides the following play() method: ``` public void play(URL url) ``` This method takes a URL as an argument, which represents the location of the sound file to be played.

Using the play() Method in an Applet

First, you need to import the necessary classes: ```java import java.applet.*; import java.net.*; ``` Then, create an instance of the Applet class and use the play() method in your Applet code. Here's an example of how it can be used: ```java public class SoundApplet extends Applet { public void init() { try { URL soundFile = new URL(getCodeBase(), "soundFile.wav"); play(soundFile); } catch (MalformedURLException e) { e.printStackTrace(); } } } ``` In this example, 'soundFile.wav' is the sound file located in the same directory as the applet's code. The 'play' method is called in the 'init()' method of the applet, which is called when the applet is loaded, automatically playing the sound file.
