    Java DataInputStream question

    hey im reading a binary file of numbers into somthing, problem is I only knew how to read from text files and there is (well I don't think), there is a .eof() in the DataInputStream.
    how I i keep reading numbers until i read the end of the input file? I know I can't put:

    while (!in.eof) {

        myInt = dis.readInt()
    } catch (EOFException e)
        System.err.println("Unexpected end of file!");
    However, you are better off checking the length of the file before working with it.
    File f = new File(filename);
    long length = f.length();
