如何解析Date formate？

Question

我要執行像

該代碼會拋出異常後登錄系統

 Process uptimeProc = Runtime.getRuntime().exec("net stats srv"); 
     BufferedReader in = new BufferedReader(new inputStreamReader(uptimeProc.getInputStream())); 

     String line; 
     while ((line = in.readLine()) != null) 
     { 
       if(line.contains("Statistics since")) 
       { 
        SimpleDateFormat format = new SimpleDateFormat("'Statistics since' MM/dd/yyyy hh:mm:ss a"); 
        //System.out.println("in ijj "+in.readLine()); 
        Date boottime = format.parse(line); 
        System.out.println("Uptime="+uptime+""+boottime); 

        uptime = System.currentTimeMillis() - boottime.getTime(); 


        break; 

       } 
     } 

的&註銷時間

Exception in thread "main" java.text.ParseException: Unparseable date: "Statistics since 6/16/2014 10:08 AM" 
    at java.text.DateFormat.parse(DateFormat.java:337)

    at programs.GetLoginTimeYaar.main(GetLoginTimeYaar.java:14)

Answer 1

嘗試

new SimpleDateFormat("'Statistics since' MM/dd/yyyy hh:mm a"); 

因爲您的日期不包含秒。

Answer 2

您必須刪除在你的模式秒：

new SimpleDateFormat("'Statistics since' MM/dd/yyyy hh:mm a");
