Java 调用批处理文件另类方法

import java.io.*;

public class Test
{
    public static void main(String[] args)
    {
        System.out.println("args : " + java.util.Arrays.asList(args));

        try
        {
            String command = args.length == 0 ? "notepad" : args[0];
            Process child = Runtime.getRuntime().exec(command);

            String line = null;
            BufferedReader reader = new BufferedReader(new InputStreamReader(child.getInputStream()));
            while((line = reader.readLine()) != null)
            {
                System.out.println(line);
            }
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
    }

}
