我用的centos6.3，想用java获取文件的创建时间，该怎么办？

Question

网上有说生成dll文件那个不会啊。。。还有要使用window下cmd那个，我在centos应该不能用吧
package hadoop;

import java.io.BufferedReader;

                            break;  
                        }  
                    }  
                }  
                catch(IOException e)  
                {  
                    e.printStackTrace();  
                }  
                finally  
                {  
                    try  
                    {  
                        if(null != br)  
                        {  
                            br.close();  
                        }  

                        if(null != ir)  
                        {  
                            ir.close();  
                        }  

                        if(null != is)  
                        {  
                            is.close();  
                        }  
                    }  
                    catch(IOException e)  
                    {  
                        e.printStackTrace();  
                    }  
                }  
            }  
        };  

        Thread thread = new Thread(runnable);  
        thread.start();  

        try  
        {  
            thread.join();  
        }   
        catch(InterruptedException e)  
        {  
            e.printStackTrace();  
        }  

        if(0 != sb.length())  
        {  
            rs = sb.toString();  
        }  

        return rs;  
    }  

}
这样获取出来的是null

当成参数传进去可以么

通过shell执行程序，创建时间当成参数传进去
