hi every one .
iam nodding my head for one basic question which is about platform independency in java..I have 6 queries
1)let us assume i have compiled a java program on windows os (obiviously windows compatible jvm) .the moment i got my class file if i run that under linux os (linux compatible jvm). will i get same output (without any modificaitons)as i got in windows os..if yes will that happen for every topic in java as swings ,applets, awt and even graphics representation works.
2)when i used windows jvm and compiled the program how can a linux jvm can understand windows jvm compiled code and run that on linux jvm ?
3)i have devoloped a java decompiler under windows os and when i give class file as input iam getting same source code which has produced that class file .will i get the same source code if i took that windows compiled class file and run that under linux (os under linux jvm)?
4)if yes when compiling i have used windows jvm then how can i get same source code if i decompile it under linux os..how can a linux jvm can produce same source code being compiled under windows jvm ..then how one can say jvm is platform dependent..and jit compiler is also platform dependent ..
5)wora (write once run any where ) if i run class file under any os will i get same to same (100% same output ) as i got during windows os
6)till the process of class file creation will the jvm would be dependent on operating system.if yes then even when decompilation or while running the program how is it producing the same output ?
please please please help me and answers my queries with patience (please sir) please. please dont send me any link or url answer them please

Don't ask the same question twice; you already have an answer from Joanne Neal here.

Closing this thread.
 
It is sorta covered in the JavaRanch Style Guide.
