Get Values Of External Launcher

Hi, I’m make a launch in Java for my unity’s game that open the game, with this script:

Runtime.getRuntime().exec("game.app");

But I want to pass values (informations) like example, I want to pass coordinates so I launch my game like this

Runtime.getRuntime().exec("game.app?cordinatex=32&cordinatez=43&cordinatey=12");

How I make this?

Nobody?
