如何验证我的字符串以特定数据结尾？

Question

I have a String

String s = "a/b/c/d/data/info";

I need to find is info exist. And info should follow right after data . How can I verify that my string ends with a particular data ( info )?

UPD

I need to find and retrieve string which follows .../data/{thisString}

Answer 1

s.endsWith( "data/info" )

is true .

EDIT: OK, so "info" is just your stand-in for any string. You could check for the "data/" with indexOf and then use substring to get just the "info" part.

  String s = "a/b/c/data/info";
  String info = null;
  if( s.indexOf( "data/" ) >= 0 ) {
     info = s.substring( s.indexOf( "data/" ) + "data/".length() );
  }
  System.out.println( info );

Answer 2

You can use:

String repl = "a/b/c/d/data/info".replaceFirst("^.*?data/([^/]+)$", "$1");
//=> info

Answer 3

Username after data/:

String s = "a/b/c/d/data/info";

System.out.println(s.split("data/")[1]);

outputs:

info
