Create an Apex Class

Next, let’s create an Apex class to debug. This class removes cold accounts from a list so that you can focus on more promising clients.

Create an Apex class called AccountViewerController.

Replace your class’s default contents with this code.

1public class AccountViewerController {
2
3
4   public Boolean removeCold { get; set; }
5   public List<Account> results { get; set; }
6
7
8   public AccountViewerController() {
9
10
11      removeCold = false;
12
13
14      results = [SELECT Id, Name, Owner.Name, Rating, BillingCity, BillingState 
15         from Account
16         WHERE BillingCity = 'Suffragette City'
17         Order By Name ASC];
18   }
19
20
21   public List<Account> getAccountTable() {
22
23
24      List<Account> accountsToReturn;
25      accountsToReturn = new List<Account>();
26      accountsToReturn.addAll(results);
27
28
29      if (removeCold==true) {
30         removeColdAccounts(accountsToReturn);
31      }
32
33
34      return accountsToReturn;
35   }
36
37
38   public void removeColdAccounts(List<Account> listToReduce) {
39
40
41      System.debug('Removing "cold" accounts');
42      System.debug('   size before: ' + listToReduce.size());
43
44
45      for (Integer i = 0; i < listToReduce.size(); i++) {
46         Account a = listToReduce.get(i);
47         if (a.Rating.equalsIgnoreCase('Cold')) {
48            listToReduce.remove(i);
49            System.debug('removed cold account: ' + a.Name);
50         }
51      }
52
53
54      System.debug('   size after: ' + listToReduce.size());
55   }
56
57
58   public void noOp() {
59   }
60
61
62}

Save AccountViewerController.cls.
