    That's hard to understand. I have no idea what is being asked.
    Are you sure you translated the assignment to English correctly?
    If you don't understand my answer, don't ignore it, ask a question.

    The assignment is to read two files, one the form letter template and the other the data that is to be merged into the letter template. The skills required are to read the files, merge the data read from the files, and generate the letters, either output to another file or files or to the screen. Which of these skills do you need help with? Show what you've tried for any of the necessary steps.

    There are several approaches, and coding each of them will depend to some degree on how you've stored the file that contains the body of the message or the letter.

    In general:

    1. Read the file that contains the body of the letter and store it in a convenient way. The definition of "convenient" may depend on what you choose to do next.

    2. Identify the '????' strings in the body of the message and replace each one in order with the 4 items in a single line of data items read from the second file.

    3. Output or save the result.

    4. Repeat until the end of the second file (the data) has been reached.

    Use buffered file reader and writer and the String methods. You can find further info on both of those by searching for tutorials and using the appropriate API pages. You may also have info in your textbook and class notes or lectures that you can refer to. It should not be the first time you are seeing these topics, and if it is, then there's something wrong that we can't fix.
