java需要关注的知识点---I0之进程控制
进程控制：

public class OSExecute {
	public static void command(String command) {
		boolean err = false;
		try {
			Process process = new ProcessBuilder(command.split(" ")).start();
			BufferedReader result = new BufferedReader(new InputStreamReader(process.getInputStream()));
			String s;
			while((s = result.readLine())!= null) {
				System.out.println(s);
			}
			BufferedReader errors = new BufferedReader(new InputStreamReader(process.getErrorStream()));
			while((s = errors.readLine())!= null) {
				System.err.println(s);
				err = true;
			}
		} catch (IOException e) {
			if(!command.startsWith("CMD /C"))
				command("CMD /C" + command);
			else
				throw new RuntimeException(e);
		}
		if (err) {
			throw new OSExecuteException("Errors executing " + command);
		}
	}
}
