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

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?

     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.

Cheers
