Question

简单的静态函数~import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;public class SysCmd
{    public static String autoExec(String cmdLine) throws IOException, InterruptedException
    {
        if (System.getProperty("os.name").matches(".*[Ww]indows.*"))
        {
            return exec(new String[] { "cmd", "/c", cmdLine });
        }
        else
        {
            return exec(new String[] { "sh", "-c", cmdLine });
        }
    }    public static String exec(String[] cmdArray) throws IOException, InterruptedException
    {
        Process p = Runtime.getRuntime().exec(cmdArray);        String line = null;
        StringBuffer result = new StringBuffer();        BufferedReader brIn = new BufferedReader(new InputStreamReader(p.getInputStream()));
        while ((line = brIn.readLine()) != null)
        {
            result.append(line + "\n");
        }
        brIn.close();        BufferedReader brErr = new BufferedReader(new InputStreamReader(p.getErrorStream()));
        while ((line = brErr.readLine()) != null)
        {
            result.append(line + "\n");
        }
        brErr.close();        return result.toString();
    }
}

Answer 1

Runtime.getRuntime().exec(cmd);我直接这样干的,还没像楼主这样写过.
