    Default Java array writing in seperate files

    I've got a array of objects and want to write each object in a seperate file. I've tryed to do this with a FileOutputStream and nio but it was too slow. Is there a better way to do this? It should also be readable.

    What do you mean by "too slow"? What are you comparing the times with?

    Can you make a small, simple program that compiles, executes and shows what you are trying to do?

    use a loop
    get next object from array
    create file for that object
    write that object to its file
    close the file
    end loop

    I already did that. I mean the best file writing method for a lot of objects. The output method itself, not the loop.

    For writing objects I've used writeObject().
