[英]Trying to put an ActionListener on a button then make it paint text
[英]trying to put a play audio method in my ActionListener
我試圖將play方法放在ActionListener
Audioapp
類中,但嘗試出現錯誤。
我已經在ActionListener
上閱讀了Javadoc,但找不到它
這是我的音頻:
public class Audioapp extends JApplet // find out how to implement play method into action listener?
{
public class Sound // Holds one audio file
{
private AudioClip song; // Sound player
private URL songPath; // Sound path
Sound(String filename)
{
try
{
songPath = new URL(getCodeBase(),"G:\\Uni\\Programming\\Rolling assignements\\Week0\\Programming week21"); // This is the place were im getting error
song = Applet.newAudioClip(songPath); // Load the Sound
}
catch(Exception e){e.printStackTrace();}
}
public void playSound()
{
song.play(); // Play
}
}
}
這是我的actionListener
:
class PlayStoHandler implements ActionListener {
public void actionPerformed(ActionEvent event) {
String computerRand = sps.computerChoice();
txtComputerRand.setText(computerRand);
String result = sps.play(Sps.ROCK);
txtResult.setText(result);
scis.setVisible(false);
open.setVisible(false);
stone.setVisible(true);
pap.setVisible(false);
win.setVisible(false);
none.setVisible(false);
lose.setVisible(false);
if (result == "User Wins"){
win.setVisible(true);
song.play(); // here i tried putting the song.play in this if section, the error I got was "song cannot be resolved"
}
else if (result == "Draw"){
none.setVisible(true);
}
else {
lose.setVisible(true);
}
}
我是一個初學者,所以很可能是非常愚蠢的基本錯誤
任何幫助,將不勝感激
songPath = new URL(getCodeBase(),"G:\\Uni\\Programming\\Rolling assignements\\Week0\\Programming week21");
URL構造函數希望第二個字符串表示相對URL,而您已經放置了文件路徑。 URL始終帶有正斜杠和一個file:
基於URL的意義不大(WAV托管在您的站點上,而不是最終用戶的HD)。
如果小程序是在站點的根目錄中由HTML加載的,而HTML中沒有聲明codebase
,並且wav稱為moo.wav
且位於名為Week0/Programming week21
則正確的路徑為:
songPath = new URL(getCodeBase(),"Week0/Programming week21/moo.wav");
但是,為了使事情變得簡單得多,至少就目前而言,將HTML,applet 和剪輯放在同一目錄中並使用:
songPath = new URL(getCodeBase(),"moo.wav");
song
是私人的。 您創建了一種播放聲音的方法,因此請使用它。
獲取您的Audioapp
實例並運行playSound()
方法。
