    Default Output an int i to a file

    The Question is as follows: Explain the difference between the output of the following two fragments of code for outputting an int i to a file

    i)

    PrintWriter outfile = new PrintWriter(new FileWriter("ints.txt"));
    outfile.print(i);

    ii)

    DataOutputStream out = new DataOutputStream(new FileOutputStream("ints.dat"));
    out.writeInt(i);

    I believe the PrintWriter coverts the stream into Unicode and the DataOutStream converts higher level data items to sequence of bytes.

    What more can be said?

    the difference between the output
    Have you tried executing the two segments?
    What do they output? Can you copy and paste the output here to show us?
    Use a hexeditor if needed.

    For your section segment, you can talk about serialization, other than that do what norm said and run the code
