java applications

can a java application be used for both Se and Nokia or it must be different?????? __________________ depends on what kind of format is the java application... if I am not mistaken both brand are using different format... __________________ I tryed using some applications from se on my nokia but they dont work so I think they must be different. __________________ java is a computer language to write program's and games, but when they compile the program into a Jar file, they add data what type of phone you use. Like what kinda screen (large, big) etc. So it's easy to devellop on game, write it in one and the same language (java) and then compile it for every mobile brand. in the past they had to rewrite a game/program for every brand based on own language.
