string Manipulation Complexity
===

I have been programming since 1 year, I have done String Manipulation so many times but never understand how its actually been done or WHATS the best way of doing it, here am talking about dynamic String.

let say I have this string

    String abc = "https://uu2020.devuueva.com/portal/mesddsa/usforeer/nance/tings/M3C102d4104/1007/tingjack/default.aspx";

I want to only this part

    "https://uu2020.devuueva.com/portal/mesddsa/usforeer/nance/tings/M3C102d4104"

characters/Names can change and are dynamic, however "/" isn't. Can someone demonstrate the Simplest and the best way of doing it.
