    Question File Class Equivalent in j2me?

    is there a File class equivalent in J2ME?
    Hi! I was wondering if there was an equivalent class in j2me to the File Class in java's standard edition? i need to know if i could somehow get the files stored in a particular folder and use those files i get in my midlet and forms. Can somebody help me? I've been going over the API and to this time I haven't found anything useful yet.

    any ideas? thanks.. ^_^

    Well, it is not exactly a file class ... but:

    InputStream iS=getClass().getResourceAsStream("/file.txt");

    use jsr75

    File access in J2ME is done via jsr75 file connection api. It is included in the series 60 sdk e.g. You open a file connection via the normal Connector class. Use an url like "file:///c:/somefolder/file.txt". You get a FileConnection object you can use to do everything you normally do using java.io.File.

    Does that help you?

    sir the problem with this code is that i would still have to know and specify the exact file-name as a parameter of the getResourceAsStream method. the situation calls for a way for me to traverse the diferent directories in the mobile phone's memory, look for the folder where the mobile phone stores the images it captures and get the filenames of these images.
    I might be mistaken sir..it would be a blessing if you could explain to me how this code could work for me? Thank you for sharing your expertise with me.

    Yes, you're right. If you know the path then my suggestion can be used.
    Otherwise you'll have to resort to the aforementioned JSR - if that is supported on your target phone.

    sir, this might sound stupid, but how do I know if my target device supports the aforementioned jsr? My target device is any series 60 device using midp2.0 profile.

    Ehrm - no, it is not a stupid question :-) Unfortunately I cannot answer it. Perhaps if you dig a bit on java.sun.com???
