由于我想使用匹配模式解析日志文件以满足以下条件，我在java中很差，不确定是否正确。请帮忙。
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
日志文件是格式
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
用Java编写代码但确定我的条件和模式不正确我怀疑是如何获得响应时间并纠正以下java代码
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
任何正文帮我修改此代码并满足以上所有以下条件。
先谢谢。

答案 0 :(得分：0)
如果没有正则表达式，您可以获得计数和大小结果，如下所示：
List<String> log = Arrays.asList(
"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",
"100.10.200.20 - - [19/Apr/2016:09:21:45 -0400] \"GET /test/nonreport/RenderForm.do?formId=18483&formType=CCT_APP_AP_TR_RSP HTTP/1.1\" 200 418032",

);
int countRequestsGE100 = 0;
int countRequestsL100 = 0;
int countNonReportRequests = 0;
int sizeRequestsGE100 = 0;
int sizeRequestsL100 = 0;
int sizeNonReportRequests = 0;
int urlOffset = 6;
int sizeOffset = 9;
for(String s:log)
{
String[] array = s.split(" ");
int size = Integer.valueOf(array[sizeOffset]).intValue();
if (array[urlOffset].contains("/report/"))
{
if (Integer.valueOf(array[sizeOffset]).intValue() >= 100000)
{
countRequestsGE100++;
sizeRequestsGE100 += size;
}
else
{
countRequestsL100++;
sizeRequestsL100 += size;
}
}
else
{

sizeNonReportRequests += size;
}
}
System.out.print(

但是我没有在你的行中看到一个计算总响应时间的地方
