java程序使用代理上网
在main函数的开始加入如下就可以了
System.setProperty("proxySet", "true");
System.setProperty("http.proxyHost", "192.168.7.33");
System.setProperty("http.proxyPort", "8080");
java播放声音文件
使用sun.audio.*可以很方便的使用java播放声音文件，例如下面这个简单的例子就可以播放声音了
package test;
import java.io.FileInputStream;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;
public class AudioTest {
public static void main(String[] args) throws Exception {
AudioStream as = new AudioStream(new FileInputStream("sound.wav"));
AudioPlayer.player.start(as);
}
}
声音文件的停止也很简单
AudioPlayer.player.stop(as);
如果循环播放和循环停止可以这么写
AudioData ad = as.getData();
ContinuousAudioDataStream cads = new ContinuousAudioDataStream(ad);
//循环播放开始哦
AudioPlayer.player.start(cads);
//循环播放停止
AudioPlayer.player.stop(cads);
