I am getting an error starting at line 205 with the variable "lastName". I am getting the 'cannont resovle symbol' error with this variable amd the other array variable I had set up to read the columns of a text file. I am thinking that since the technique of reading the text file is embedded in its own prodecure that maybe the variables are not recongized by other procedures.

I would appreciate any help that anyone can provide. I am at a loss as to what to do. Here is a copy of the text file I am using. Thanks in advance.

Line 205? Where's line 205? Please repost using Java code tags. which will add line numbers, or highlight line 205 in red.

[code=JAVA] // paste code here

[/code]

You have a scoping issue. You define lastName in function readFile. lastName is not a class data member, so it goes out of scope once the readFile function is over. You try to use it in the addTextToTextPane function. You can't do that. If you intend lastName to be global/class variable, you should declare it at a global scale. Anything initially declared inside of a function is not a global/class variable.

public class anExample{
private Object obj; 
private static Object obj2;
public Object obj3;
public static Object obj4;

public static void main(String[] args){
}

//other methods

}

From a method inside the class with an instance of anExample:
You can refer to (use) obj and obj3.

From a static method inside the class without an instance of anExample:
You can use obj2 and obj4. Being static means the class has one copy of them that is shared by the entire class.

From a method inside a different class, with an instance of anExample:
You can refer to obj3

From a method inside a different class, without an instance of anExample:
you can refer to obj4

So the answer to your question would be the following, although I didn't look at your code. Either use a public or protected variable in your main driver class (the one thats run when you first start the program), use a private instance variable and provide accessors and mutators, or you could use a static variable. In either case, if you wanted easy access to the variable in both of your classes, consider using constructors that take the parameter as an argument.

Yes, the above example will work, as long as you declare x properly. It should say public static int x = 37;

Thanks for the pointers...I think I am going to try something like this:
public class Global {
     public static int = 37;
     public static String s = "aaa";
}

public class test {
     public static void main(Strings args[])
     {
          Global.x = Global.x + 100;
          Global.s = "bbb";
     }
}
From what I see in this example, I will go ahead and implement something similar and rewrite my array varaiables accordingly......I'll reply with the results.

Why create a new class? How about just changing lines 18 - 28 from your original code and split them up? Put the declarations at the class level, put the rest of the lines in the constructor or keep it them in the readFile function...

public class CustomerInfo extends JFrame implements ActionListener
{
		String[] custID;
		String[] firstName;
		String[] lastName;
		String[] addressOne;
		String[] addressTwo;
		String[] myCity;
		String[] myState;
		String[] myCountry;
		String[] productionID;


         public void readFile()
	{
		BufferedReader br = null;
		custID = new String[100];
		firstName = new String[100];
		lastName = new String[100];
		addressOne = new String[100];
		addressTwo = new String[100];
		myCity = new String[100];
		myState = new String[100];
		myCountry = new String[100];
		productionID = new String[100];
		int num = 0;

                // rest of code
        }
}

Now you can use the variables in lines 3 - 11 globally. Or again, if you are only calling readFile once, you can put the new commands in the constructor.

Sorry about that. I didn't think about adding the line numbers. Here it is again...hopefully.

That's the conclusion that I was thinking about also...I am at a lost as to the best way to go about making those array variables global...I dont suppose you have any suggestions? One example would be a good start for me to learn from.

dbwalters 0 Newbie Poster · Answer 3 · 2008-11-05T03:04:05+00:00

Thanks for the pointers...I think I am going to try something like this:

public class Global {
     public static int = 37;
     public static String s = "aaa";
}

public class test {
     public static void main(Strings args[])
     {
          Global.x = Global.x + 100;
          Global.s = "bbb";
     }
}

From what I see in this example, I will go ahead and implement something similar and rewrite my array varaiables accordingly......I'll reply with the results.

@ Vernon: I got the impression that he isn't creating a new class, he was just giving an example of what he thought the concepts were, and he's going to use those concepts in the class he currently has. No?

"Global" is not the same as instance level scoping. Careful about using those terms interchangeably.

Scoping issue aside, I have to wonder why you nine different unrelated arrays to hold the properties of what should probably be a one dimensional array of objects that contain that data?

dbwalters 0 Newbie Poster · Answer 6 · 2008-11-05T03:59:07+00:00

Well, I got the program working by creating a seperate class that defines the individual arrays Globally. I mainly had to use seperate arrays to hold individual data because of 3 Searches performed by using a particular field...either by Last Name, Production ID or State.

Right, wrong or indifferent...this code now works. Now, I just have to format the Pane so that all of the data fits....thanks again for everyone's help and insight. I appreciate the information and will use the ideas.

BestJewSinceJC 700 Posting Maven · Answer 7 · 2008-11-05T11:51:58+00:00

I think you could use a 3D KD tree for that. Well, actually, not really, since a KD tree works by analyzing the first key, then second, then third, etc, depending on what level you're on. But I don't see why you can't put all the data into one array, then simply search through the data according to whatever characteristic you're looking for. And Ezzaral, my professors always use Global to refer to what would be the same as a 'static' member of a class in Java. But if you're saying an instance of a class doesn't contain Global variables (I mean, that Global variables aren't class instances), I agree.

I haven't looked at this guy's code since I responded to this thread a while ago (and judging by what I said in my response, I didn't look too hard then, either) but if I were you, I wouldn't be using his code to learn about Java.

Would you happen to know what this error means?, I just don't see how the array is out of bounds...if my understanding is correct...I'm a veteran on visual basic and know a little of C++ but Java seems a bit confusing

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 8

Thanks

It means the code attempted to access the ninth element of an array that does not have nine elements. Your stack trace would also tell you what line that occurred on. It's probably on one of the lines in readFile() where the data is being put into the arrays after the split().

You are so freaking right, there were some empty commas and this caused the search to overlap..

Thanks a lot!!!
