Java linux lame .wav音频转mp3 并且压缩

public class Test{

    public static void main(String[] args) {
try{
        String shellString = "lame -b 16 /java/5/a.wav /java/5/a.mp3"; 
        String[] cmd = new String[]{"sh","-c",shellString}; Process process = Runtime.getRuntime().exec(cmd);

        //Process process=Runtime.getRuntime().exec("lame -b 16 /java/5/a.wav /java/5/a.mp3"); // lame 你的.wav文件,简易版

process.waitFor(); //阻塞，直到上述命令执行完,一定要在文件close()关闭前面
          process.getOutputStream().close();
          process.getInputStream().close();
          process.getErrorStream().close();

       }catch (Throwable e){

     }

    }

}

解决java使用Runtime.exec执行linux命令不成功问题

关键问题在于 waitFor( ) ; 关于更多解释 , 请看 http://lelglin.iteye.com/blog/1487351
