    Default I need a simple loop code

    Hello, I have a very low level knowledge of coding. I have a code that works inside of Adobe Live Cycle (for a PDF). The formula pre-populates feils based on the selection in the first feild. What I have created below works perfectly, but I do not want to write a string of code for every number from 1-200. I know there is a way to fix this, I just do not know how to code it. Can anyone help and give me the exact code I would need to type to create this and how I place it.

    if (this.rawValue == 0)
    {
    this.parent.Billing_State.selectedIndex = 0;
    this.parent.Rep_Code.selectedIndex = 0;
    this.parent.SD_Account.selectedIndex = 0;
    }
    if (this.rawValue == 1)
    {
    this.parent.Billing_State.selectedIndex = 1;
    this.parent.Rep_Code.selectedIndex = 1;
    this.parent.SD_Account.selectedIndex = 1;
    }
    if (this.rawValue == 2)
    {
    this.parent.Billing_State.selectedIndex = 2;
    this.parent.Rep_Code.selectedIndex = 2;
    this.parent.SD_Account.selectedIndex = 2;
    }
    if (this.rawValue == 3)
    {
    this.parent.Billing_State.selectedIndex = 3;
    this.parent.Rep_Code.selectedIndex = 3;
    this.parent.SD_Account.selectedIndex = 3;
    }

    Look at using a for loop. See the tutorial for details:
    The for Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

    Also there are lots of sample codes here on the forum that use for loops.
    If you don't understand my answer, don't ignore it, ask a question.

    Thank you for the link. I have already been there and read it. I have very little experince, so I do not know how to apply what is at the link to my specific scenario. If anyone can show me more specifically how to apply the for loop to my exact situation, it would be much appreciated.

    How do you want to use a loop with the code posted in post#1?

    What is the relationship between the value of the variable: rawValue and the value assigned to the 3 variables inside all the if statements?

    Default Re: I need a simple loop code

    I have a list with 200 Names, their state, a code assigned to them, and an account number. The integers are assigned to the correlating information on those lists via Adobe.

    The list would start like this:

    ABC Co – CA – AAA – 12345
    EFG Co – AZ – BBB – 54321

    Adobe assigns a value to each item in the list based on its order:
    ABC Co(0) – CA(0) – AAA(0) – 12345(0)
    EFG Co(1) – AZ(1) – BBB(1) – 54321(1)

    Adobe assigns an integer to each number starting at 0, thiss integer is used to reference the information, and pull it up.

    In the list above ABC Co is rawValue
    CA is Billing_State
    AAA is Rep_Code
    12345 is SD_Account.

    Even though all 4 lists are separate, I will be referencing the same number accross each list, every time (like I have started to type in my code).

    Example: I will always reference the number 1 across each list, I will never reference 1 from the 1st list 4, from the second, 3 from the 3rd and 11 from the fourth.

    Would something like what I have below work (I’m sure there are many errors in what I just typed)

    public static void main(String[] args){
    for(int i=1; i<200; i++){
    if (this.rawValue == i)
    {
    this.parent.Billing_State.selectedIndex = i;
    this.parent.Rep_Code.selectedIndex = i;
    this.parent.SD_Account.selectedIndex = i;
    }}

    What happens when you compile and execute it?

    What is the relationship between the value of the variable: rawValue and the value assigned to the 3 variables inside all the if statements?
    Why the need for a loop? Why not assign directly?

    Default Re: I need a simple loop code

    Thank you for the help!

    The relationship between the 4 is that they all share the same integer value that has been assigned to them. They appear in 4 different places on a form, but they are all related and belonging to 1 company. There are 200 companies that have 1 relationship with the 3 other variables.

    I'm not exactly sure that I need a loop. What I really trying to figure out is if there is a way of writing the code below without having to wright the same code over and over 200 times, when all I am doing is increasing the number by one.

    if (this.rawValue == 0)
    {
    this.parent.Billing_State.selectedIndex = 0;
    this.parent.Rep_Code.selectedIndex = 0;
    this.parent.SD_Account.selectedIndex = 0;
    }
    if (this.rawValue == 1)
    {
    this.parent.Billing_State.selectedIndex = 1;
    this.parent.Rep_Code.selectedIndex = 1;
    this.parent.SD_Account.selectedIndex = 1;
    }
    if (this.rawValue == 2)
    {
    this.parent.Billing_State.selectedIndex = 2;
    this.parent.Rep_Code.selectedIndex = 2;
    this.parent.SD_Account.selectedIndex = 2;
    }
    if (this.rawValue == 3)
    {
    this.parent.Billing_State.selectedIndex = 3;
    this.parent.Rep_Code.selectedIndex = 3;
    this.parent.SD_Account.selectedIndex = 3;
    }

    they all share the same integer value
    That should make the light come on. If you ALWAYS want to assign the value of the rawValue to the three fields, why all the tests? One if test to check that the value is in the desired range and then 3 assignment statements. Done.
    If you don't understand my answer, don't ignore it, ask a question.

    if the first assigned value is 0, why is your loop starting with 1?

    Norm,
    Thank you again for your help. Could you show me how that would look?

    Starstreak,
    The loop I made up above is something I basically guessed at when putting together. I should have put i = 0, but I'm sure there are 10 other isues that could be pounted out with that code. On a scale of 1-10 for Java experience, I am a 1.5.

    Default Re: I need a simple loop code

    What part are you having trouble with?
    The if test to check if the value of rawValue is in range. What are the valid values?
    The 3 assignment statements

    pseudo code:
    test if in range
    if true, then assign values to the three variables
    If you don't understand my answer, don't ignore it, ask a question.

    Norm,

    Thanks again for your help. Can you show me what this would actually look like in code. What I am reading right now is like picking up a book in French. Any help is appreciated.

    What statements are giving you the problem?
    The if statement? You are using them in the currently posted code.
    See: The if-then and if-then-else Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)
    The assignment statements? Again there are assignment statements in the code.
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: I need a simple loop code

    If I created something like this:

    if (this.rawValue == i)
    {
    this.parent.Billing_State.selectedIndex = i;
    this.parent.Rep_Code.selectedIndex = i;
    this.parent.SD_Account.selectedIndex = i;
    }


    How do I get the whole numbers 1-200 assigned to i? Maybe I am trying to attack this problem wrong?

    If I use the if statment, doen't that lead me back to where I started, having to write the same code 200 times?
