关于String提取字符，菜鸟求指教

Question

String a="showRunningAll();window.location='../../../../../SISEWeb/pub/studentstatus/studentBalanceAction.do?method=doStudentQuery&gzcode=q2An2BULSzE3GXHlT2tNrA=='"我想提取
a的SISEWeb/pub/studentstatus/studentBalanceAction.do?method=doStudentQuery&gzcode=q2An2BULSzE3GXHlT2tNrA=='
这部分 应该怎么操作？

Answer 1

string = string.subString(0,string.lastIndexOf("/"));
意思是把0到最后一个“/”之间的字符去掉，我看别人代码这么写的，自己没用过

Answer 2

哥们可以把java api翻开 好好看看String 类得方法.....

Answer 3

String str=a.subString(lastIndexOf("/")+1,str.length-1);

Answer 4

String str=a.subString(lastIndexOf("/")+1,str.length);

Answer 5

substring lastindexof is good

Answer 6

如果“SISE”固定的话
String a="showRunningAll();window.location='../../../../../SISEWeb/pub/studentstatus/studentBalanceAction.do?method=doStudentQuery&gzcode=q2An2BULSzE3GXHlT2tNrA=='";
int point=a.indexOf("SISEWeb");
System.out.println(a.substring(point));
