    Default import my text file to JTable by using JFilechooser

    can you please help me how to read the text file to JTable by using JFilechooser ?
    Even the text file contains the specific charecters line length
    eg: idUsernamePasswordEmailAgeGender ( ID = 2 Chars, Username = 10 chars ( if username not having 10 chars means, it include space for that, password = 5 chars, email = 5 chars, Age = 2 chars, Gender = 1 chars)

    Those are different issues:
    1) find path to file using JFileChooser
    2) read data from file at a given path
    3) parse data into fields
    3) put fieldsinto JTable

    What have you tried for each of the above?
    Please post your code (wrapped in code tags) that shows what you have tried.
    Describe any problems you are having.
    If you don't understand my answer, don't ignore it, ask a question.
