    Default Java relative path of a static class

    Hello everyone!

    For my 'tanks' game which I am developing in Java I need to read a text file in which the map's data is stored.
    I made a new class for this called 'MapReader'.
    However, I would like to be able to use the 'read' function of the class without instantiating a new MapReader object.
    That's why I made it a static class.

    Now my problem is that I can't seem to find a way to get the relative path which is needed to load the file.
    If it weren't static I would just be able to use new File(getClass().getResource("/maps/map.txt"));

    You can use the .class keyword to get the Class object of a given class, eg
    MapReader.class.getResource(...)

    Thank you for your answer Copeg!

    I've already tried your solution and thought it was wrong.
    Now I realise I was looking at it the wrong way and that it actually works.. (:

    But the reason it wouldn't work was that I had a space character in the path!

    If I printed out the path it would replace the space character by a '%20' (hex for 32, which is it's ASCII code!)

    I solved the problem by simply removing the space character.
    But.. if I really wanted to keep the space for some reason, would the best solution be finding the path this way and then converting the %20 to a space character?

    Don't know the answer off the top of my head, but will recommend naming of resources stick to a certain convention similar to package and class naming to avoid these issues: for instance only certain characters allowed, replacing spaces with underscores, etc...
