    Default Reading DTM (digital terrain managment) files

    Hi guys.

    I understand that in Java Eclipse that to read files, the files have to be within the folder of the java program so I have put the files into the folder of the java program where all the files to do with the DTM file reader is.

    Thing is I haven't I clue what code to type up to be able to read the DTM files. I know about needing the required tools to such as a file reader, or buffered reader etc but I haven't a clue either if these are the correct tools.

    Could someone point me in the right direction.

    The program should be able to print out the highest peak and lowest peak data ranges from the DTM files and also be able to print out this information from the DTM files to the console window within java eclipse.

    A standalone java program (without an IDE) can read a file anywhere on your PC.

    What is the internal format of a DTM file? Does it have records? What data is in a record? Given that information, you should be able to write a program to read a DTM file and extract any data you are interested in.

    Have you asked google if there is a package to read a DTM file?
    If not, you may have to write your own.
    If you don't understand my answer, don't ignore it, ask a question.

    Thanks for your reply.

    The assignment is asking me to write up the program from scratch to show I can do it and also document what each stage does. Documenting the stages of the code isn't a problem as it's a case of making it up.

    I can't use packages I don't think to read DTM files as I said before it has to be written from scratch.

    If you know what the layout of the contents of the file is, there shouldn't be a problem writing a program to read the file and extract data.

    Apparently it's all numbers but I haven't a clue what the layout is or anything as I've never touched on java programming ever...

    I haven't a clue what the layout is
    The first thing you must do is get the layout of the file. Without that you will not be able to get any information from it.
    I've never touched on java programming
    You would need to know what is in the file to use any programming language to get data from the file.
