Creating Lemmings Game, need platforms.

Hi i am trying to build a game like lemmings, this ones called phlegmmings.... i have got as far as creating the array of phlegm but am stuck on the best way to create platforms that the phlegm will walk on / fall off.
How do i create levels or platforms to build my game, i think its some kind of collision detection but really need a hand.
any help would be appreciated.

// A boolean to let us know if the game is over
boolean gameOver = false;

timer.start(); //start the timer

not sure if that is the best way to post code but here it is.....
