因爲我想使用匹配模式解析日誌文件以滿足以下條件，所以我在java中很窮，不確定是否正確。請幫助。Java中需要的匹配模式來解析日誌文件
total count of report requests with size >=100kB
total count of report requests with size <100kB
total count of all non report requests
total response time of report requests with size >=100kB
total response time of report requests with size <100kB
total response time of all non report requests
total size of report requests with size >=100kB
total size of report requests with size <100kB
total size of all non report requests
日誌文件的格式
100.10.200.20 - - [19/Apr/2016:09:21:45 -0400] "GET /test/report/RenderForm.do?formId=18483&formType=CCT_APP_AP_TR_RSP HTTP/1.1" 200 418032
Java編寫，但肯定我的條件和模式是不正確編寫的代碼和我的懷疑是如何得到的響應時間和糾正下面的Java代碼
total response time of report requests with size >=200kB
total response time of report requests with size <200kB
total response time of all non report requests
任何機構都可以幫助我更正此代碼，並滿足以上所有條件。
在此先感謝。
代碼：
