java调用'shell'脚本或'cmd'命令,并得到返回的结果集

ShellCmdLog.class中的代码：
public class ShellCmdLog extends Thread
{
    private boolean bLog2Error;  //是否打印错误Error标志
    private InputStream ins;     //待转换文件输入流

    /**
     * 设置是否打印错误Error，设置待转换文件的输入流
     * @param is    待转换文件输入流
     * @param flag  是否打印错误Error标志
     */
    public ShellCmdLog(InputStream is, boolean flag)
    {
        super("ShellCmdStream" + (flag ? "-error" : "-out"));
        bLog2Error = flag;
        ins = is;
    }

    /**
     * 执行转换线程
     */
    public void run()
    {
        if (ins != null)
        {
            InputStreamReader isr = new InputStreamReader(ins);
            BufferedReader br = new BufferedReader(isr);
            try
            {
                String line = null;
                while ((line = br.readLine()) != null)
                {
                    if (bLog2Error)
                    {
                        System.out.println("Shell_Err>" + line);
                    }
                    else
                    {
                    System.out.println("Shell_Out>" + line);
                    }
                } //end of while(true)
            }
            catch (IOException ioe)
            {
            System.out.println("ShellCmdLog error:" + ioe);
            }
            finally
            {
                try
                {
                    if (isr != null)
                    {
                        isr.close();
                    }
                } catch (IOException e)
                {
                    e.printStackTrace();
                }
                try
