parsing a string

[jrthor2]

If I have a string that has a value of:

/page/subpage/test-page?p_id=...

How can I get just "test-page" out of that string? I don't want anything before or after that.

Thanks!

Use lastIndexOf to get positions of / and ? and substring it

String str = "/page/subpage/test-page?p_id=";

        int slashPos = str.lastIndexOf("/");
        int steps    = str.lastIndexOf("?");

        String testPage = str.substring(slashPos+1, steps);
        System.out.println(testPage);

There will be situations where there is no query string, and when testing the code, i am gettting a StringIndexOutOfBounds exception when the url does not have a ?. How can I solve this?

Thanks!!!

If lasIndexOf cant find the value it's looking for it'll return -1.
So use a if statement for the substring if steps > 0 use str.substring(slashPos+1, steps);
else str.substring(slashPos+1);

If it's even more complicated than this, maybe you should use regex

yeah, that's actually what I did and it seems to be working fine.
