How to search within a list?

[Mike Croteau]

I have created an address book which holds information including first name, last name, address, city, etc. I have text fields for each of those values in which I use to set. How can I use those text fields to type in part of an address to find an address that matches within my list collection? Thanks in advance.

i am assuming you have a seperate class for address which contains name, city, etc... and you are using arraylist or set from collections interface.
you can implement comparator and can make a search or if you are using arraylist then

public BankAccount find(int accountNumber)
   {
   //  for (int i = 0; i < accounts.size(); i++){   BankAccount a = accounts.get(i);   sum = sum + a.getBalance();}
      for (BankAccount a : accounts)
      {
         if (a.getAccountNumber() == accountNumber) // Found a match
            return a;
      } 
      return null; // No match in the entire array list
   }

in your case BankAccount will be replace by Address and then replace getAccountNumber() to your needs for searching.

Hope this helps

Thanks for the post! This is helpful, however, have another element to throw into the pot. What if I needed to do a partial search... example:

Let say you have a list of animals:

Cat
Dog
Bat

And you search for animals containing "at" within the name. You need to return: Cat, and Bat. How can i do this? Thanks again!
