java如何播放wav文件
倡导经常使用jmf（java media framwork），这样就能播放mp3等泛滥格局的音乐了；去sun官方下一个jmf，装置好后，把包引入便可经常使用，给出例zi代码：经常使用方法：结构函数中传入文件门路名即可，播放、暂停、继续、中止等配置均已成功。 /************************************************** Subclass: MusicPlay*************************************************/ public class MusicPlay implements Runnable {private Time zeroTime = new Time(0);private Player player;private boolean isloop = false;/************************************************* * Function: MusicPlay Description: constructor, load the music file and * get ready for play Called By: MultiMedia() *************************************************/// 实例化各个参数 filename 为文件名，可为相对门路public MusicPlay(String filename) { File file = new File(filename); try {player = (()());(new ControllListener()); } catch (NoPlayerException e) {(); } catch (CannotRealizeException e) {(); } catch (MalformedURLException e) {(); } catch (IOException e) {(); }}/************************************************* * Function: isRunning Description: test if this music is playing Called * By: *************************************************/public boolean isRunning() { return () == ;}/************************************************* * Function: play Description: play the music for once Called By: * resumeAll() *************************************************/// 只播放一次性public void play() { if (!turnOff)();}/************************************************* * Function: replay Description: replay the music Called By: musics that * will be played many times will invoke this methed *************************************************/// 再播放一次性public void replay() { if (turnOff)return; if (() == )(zeroTime); ();}/************************************************* * Function: stop Description: stop this music Called By: stopAll() of * upper class,suspendAll() of upper * class,BackroundForMenuPanel,GameOverPanel *************************************************/public void stop() { ();}/************************************************* * Function: close Description: dispose the music Called By: closeAll() * of super class *************************************************/public void close() { (); ();}/************************************************* * Function: loop Description: make the music played repetitiously * Called By: music that will repetitious play *************************************************/// 循环播放public void loop() { if (turnOff)return; isloop = true; (); replay();}/************************************************* * Function: run Description: trig this music Called By: Override method *************************************************/@Overridepublic void run() { loop();}/************************************************* * Subclass: ControllListener Description: listener for playing and * implement playing repetitiously *************************************************/// 经过对播放进展的监听，成功循环播放private class ControllListener implements ControllerListener { public void controllerUpdate(ControllerEvent e) {if (e instanceof EndOfMediaEvent) { if (isloop) {(new Time(0));(); }} }} }
Java建设一个闹钟厂,闹钟属性:状态、色彩、期间(设置为整型)闹钟行为:响铃,设？

1.最后一句话改成((0)()(1)());留意这里是item(1)不是0，而你的firstChlild其实相当于item(0)2.这是为什么呢？由于你的firstChlild不是Element类型的。
上方给你写下就明确了。
在(());上方加上上方这点物品Node fatherNode = (0);NodeList childNodes = ();(());for (int j = 0; j < (); j++) { Node childNode = (j); // 假设这个节点属于Element ,再启动取值 if (childNode instanceof Element) {(子节点名为: + ()+ 相对应的值为 + ()()); }}
