Unlimited Array Elements

**exdox77** · 06-30-2010, 05:53 AM

I have an array of people, lets say 20. But later I need to add 20 more to the array. right now my code is come like this.

String array[] = new String[20];

now this will only let me add 20 strings to that. I want to be able to add as many string to that array as possible. How can I accomplish this.

There is a Collection class that implements all sorts of structures that grow as you add more elements to it. See List, Map, Set etc. You'll find what you need there. Alternatively, make your own class that implements a growing array, or some other structure, like a Linked List. That would be better practice in the long run.

okay I was having trouble setting my arraylist with objects from a different class. Lets say I have a class name Add, where I set the names and the phone number of that person. but when i try to put this is an arraylist it doesnt let me. would i be able to do this?

Think of types (classes) and instantiations (objects) thereof; think of a Person class that has a 'name' member and a 'phone' member and you can add Person objects to your Lists instead of just Strings and ints that have to represent those names and phone numbers? b.t.w an int is a very bad type for the representation of a phone number. You are working with Java so why do things the Fortran or Pascal old fashioned way?

kind regards,

Jos

Is there a way you can provide me a quick example?

Sure, first create a Person class:

Java Code:

public class Person { /* implementation details go here */ }

and you simply use a list that can store those Persons:

Java Code:

List<Person> persons= new ArrayList<Person>();
// interesting code goes here

kind regards,

Jos

it doesnt let me

When you get errors, copy and paste them here with your questions.

Also copy your code here so we can see what it's doing...otherwise we're just guessing.

the IDE tells me, "Array required, but java.util.List<Add> found" not sure what this means. I am guessing that I just cant swap out my old array with and Arraylist.

Sorry about the problems I am rather new to java and programming in general.

Where/what line does the IDE point to as having an error?

Please use code tags when posting code. Your unformatted code is hard to read.

**exdox77** · 07-12-2010, 09:43 PM

sorry about that wasnt thinking, anyway the lines below throw and ide error:

Java Code:

        file.format("%s", "Name: " + donorArray[i].getName() + "\n");
        file.format("%s", "Adress: " + donorArray[i].getAddress() + "\n");
        file.format("%s", "City: " + donorArray[i].getCity() + "\n");
        file.format("%s", "State: " + donorArray[i].getState() + "\n");
        file.format("%s", "Zip: " + donorArray[i].getZip() + "\n");
        file.format("%s", "Phone: " + donorArray[i].getPhone() + "\n");
        file.format("%s", "Number of Donations: " +

If you're going to use ArrayLists, you'll then want to read the tutorials on how they're used. For one, you don't use array indices [i] but rather the get(int index) method. The tutorial should explain all.

**Norm** · 07-12-2010, 09:51 PM

donorArray[i].getName()

That line is referring to donorArray as if it were an array. Is it an array or what type is it?
The IDE is telling you what it sees and doesn't understand.

**exdox77** · 07-12-2010, 09:57 PM

Ok the data type are objects from the Add class.

**Fubarable** · 07-12-2010, 10:00 PM

He's talking about the type of the donorArray variable which is an ArrayList. Again, you don't use indices or indexes with ArrayList -- don't do donorArray[i]. Instead use the get method. Again, please read the tutorials as they will explain better than we can.

**Norm** · 07-12-2010, 10:01 PM

Is donorArray an array? The [] following its use in the statements the IDE points to says it should be. Is it?

**exdox77** · 07-12-2010, 10:05 PM

DonorArray was an array of type Add, which I converted to an arraylist to grow as I add more contacts.

**Norm** · 07-12-2010, 10:17 PM

DonorArray was an array

Now you have to change all usages of it to match its new type. Fubarable has explained what you need to do to use that type.

**exdox77** · 07-12-2010, 10:38 PM

Kind of figured that out after reading that. I will read the tutorial, do you know the link for it.

**Tolls** · 07-13-2010, 08:54 AM

The Collections tutorial.

ETA: Oh yes, and when I requested the code (and I admit I didn't word it terribly well) I meant the relevant bit of code for the error...;)
