Read a URL from the console. Then display a space-delimited list of all the parameters (The parameters follow the "?" and are separated by "&", e.g. "lvl=15"). The URL contains at least 1 parameter. If the obj parameter is present, pass its value to the relevant alert method.

Wow! I see from all the comments here and from the questions in the help section, that I literally reinvented the wheel (Although I did see others doing similar types of algorithms). Basically, I ended up creating two Arraylists, one with all the individual characters of the URL, and one <Integer> with the indexes of characters '=' and '&'. next I looped through the second Arraylist using its elements to get to = and & indexes of the first Arraylist and creating subStrings out of it to print to the console. next I checked if any of the subStrings equal "obj" to call alert methods. I spent from last Thursday to this Wednesday on it (because i had resolved not to use the help section or comments) even asking at one point, a question on stackoverflow [that was down-voted thrice within 15 minutes]. What a waste of TIME! :-)

I didn't use URL, but split came in handy.
