read file + write file = copy file

hi, im trying to read a contents of a file (from a class), store it in a variable/object and pass it to another class and that other class will write it to a file. now im stuck at reading the contents of the file and passing it to another class, ive tried using byte[] as the datatype (i think thats the problem), but it doesnt work. what other datatypes can i use? assuming that the file could be anything (.jpg, .mp3, .zip, etc, etc). what other datatype can i use and how to use them to read/write?
thanks

     FileInputStream YourInputStream=new    FileInputStream(YourReadFile);
     File f=new File(YourReadFile);
     byte b[]=new byte[f.length()];
     YourInputStream.read(b);
     B b1=new B();
     b1.write(b,"Your Out Put File");
   //and other codes

where you need to write method in class B and bla bla bla

And I say you are going in right way only. You should use byte array only for reading binary files.

Can you post some code for us to look at?

Usually, reading byte from a file when you don't know the type of file is probably the best way to do it...

Are you getting an exception or something?
