    Default File array to String array?

    I would like to know how to convert a file array to a string array so it can be displayed on a JList.

    how to convert a file array to a string array
    Not sure what a file array is? Can you explain?

    You could read each record from the file and put it into the next slot in the array.
    The problem with arrays is that you need to make the array have enough slots to hold all the data that will be put into it. Using a class like ArrayList keeps you from having this problem.

    By File Array if you mean that it is an array of File objects then you can use
    file[i].toString();
    file[i].getAbsolutePath();
    file[i].getPath();
    //etc
    methods to represent the file's path/information.

    +thanks this seems to work. on another issue, it seems that when i try to export into a JAR file, and select appropriate project, the manifest file isn't there to be included... and when i run the jar file (i want to be able to run it by regularly opening it as any other file) it says it can not find the class manifest...

    To execute the classes in a jar file when "opening" the jar file, the jar file must contain a manifest file with a Main-Class: record that names the starting class to be called.

    Yes, but in Eclipse (java editor i use) it usually includes/makes it automatically for you, and it wasnt there. is there a way to make the manifest file from scratch? like, make a text document and rename?

    ok, well i just found out how to make it work. i was rushing it too much and in a view in the wizard to export it there was an option to choose the main class. and i failed to see it.
