Java GUI

  1. Nov 27, 2007 #1
    When using GUIs, you can enter an integer or a double into an input dialog box, then you can set a variable equal to the input such as below:

    int variable = Integer.parseInt(String name);


    double variable = Double.parseDouble(String name);

    If I enter a string into the dialog box, and I want to set a variable of the string type equal to that input, what code can I use that's similar to the code above? I can't seem to find anything in my text book.

    I'm looking for something like: String variable = String.parseString(String name);

    Any help is appreciated.

    I'm not totally sure I understand the question, but I'm pretty sure that what you want is the



    ANY object in Java should have a toString() method (although sometimes it will not return what you expect) and so it is analogous to the Type.parse(object) methods..

    I'm no expert on Java but I would think that the reason you NEED "Integer.parseInt(String name)" and "Double.parseDouble(String name)" is to change a string to an integer or double. You don't NEED a function to change a string to a string!

    Just "String variable= name;" should work.

    Thank you for the replies.

    I think HallsofIvy hit the nail on the head. I was doing it assbackwards. I should have imported a GUI package, and used the methods within that package to display a string.
