    Default Need help on my code

    Hi everyone. I’m a beginner in Java. I’m trying to write a program that will simulate melee combat between different races and different species. However, I’m having trouble. When I press the ‘go’ button, I need it to set default values to combat, defense HP. But when I tried to code it in, it wouldn’t give me a value, just my placeholder - %d. Can somebody explain to me or lead me to the right direction in terms of getting the value put in when I press go. Or if someone could alter my code to show me and explain what it does, that would be greatly appreciated. Either way, thanks. Also sorry if this isn't well written in the forums.

    Please edit your post and wrap the code in code tags to preserve formatting and make it easier to read.

    it wouldn’t give me a value, just my placeholder - %d
    Can you explain what happens? I don't understand what you are trying to say.

    also what happens is that "%d,int a" is displayed not my value, in this case 25. all it displays in the textfield is "%d,inta" i want to know how to make it so wben i press "Go" it gives my value not my placeholder. sorry about the format of my first post im new to this site.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    "%d,int a" is displayed
    Where is that String displayed? I see lots of textfields that are loaded with: "%d"
    If on the console window, please copy the full contents of the console window and paste it here.

    Okay, I think I wrapped it. Tell me if i did it incorrectly, though.

    I can't copy the window right now since I am not on my programming computer. What I am trying to do is get FirstTextField to give me a value of 25 when I press Go on my screen. I tried to set it to "%d, int a" in hopes of it reading the value of int a, which is 25, and getting it to set the value when I press go. But when i do run my program FirstTextField always reads "%d, int a" which I don't want. I want it to be blank into a user presses go. At that point it will give me a value of 25. I am really sorry if I am hard to work with I have only started programming for about four months,

    If you preload a textfield with a String and then call the textfield's getText() method, you will get back what you put into it. If you put "%d" in the textfield that is what you will read back with getText().
    If you don't understand my answer, don't ignore it, ask a question.

    Sorry, I don't know what you are trying to fix. Can you explain what you see when the code executes and what you want to change?
    What do you want the program to display?
    What do you want the program to do when the "Go" button is pressed?
    If you don't understand my answer, don't ignore it, ask a question.

    Okay, again sorry if I am hard to work with, but I want my program to display blank TextFields when it is first started. Then when the GO Button is pressed I want the values put in. For example combat I want to be 25 when I Press Go and only when I Press go.

    display blank TextFields when it is first started.
    Then don't call the setText() methods with Strings until you want data put in the textfields.
    when the GO Button is pressed I want the values put in
    When the "GO" button is pressed, then in the listener method call setText() to put the values in the textfields.
    If you don't understand my answer, don't ignore it, ask a question.

    For the first part how would I go about changing my code so it wont call the setText() methods?

    Two ways:
    delete all the lines that call the setText() method
    Put the calls to the setText() method inside a comment block: /* ... */

    Okay which line of code is calling the setText()? I can't see it? Because I thought I needed to place getText in order for the setText to be called. I'm guessing this is wrong?

    Do you have the source in an editor with a Find function?
    In the editor: Open the Find function and typing in: setTexT
    If Find works, it should position the editor to a line with setText

    If your editor does not have a Find function, change to another editor.

    Oh. I think I'm getting it. Remove setText(). from the method and move into the action listener only?

    Can the setText() method WHEN you want to change the contents of a textfield.

    If you are confused about when a section of code is executed, add println calls to the different sections and have them print out a message when they are executed. Looking at the messages as they are printed you'll know which section has been executed.
