Adjust the Loop

Add a List FOR loop to iterate through the bankAccts list that you created. 

1. In the Developer Console, open the Execute Anonymous window.
2. Replace the existing code with this code:

   //From the BankAcct class, instantiate an object named chkAcct
   BankAcct chkAcct = new BankAcct();
   //Set the accttype attribute of the chkAcct object to Checking
   chkAcct.accttype = 'Checking';
   //Set the acctName attribute of the chkAcct object to D.Castillo-Chk
   chkAcct.acctName = 'D.Castillo-Chk ';
   //Invoke the makeDeposit method with 150 as the argument
   chkAcct.makeDeposit(150);
   //From the BankAcct class, instantiate an object named bankAccts
   BankAcct savAcct = new BankAcct();
   //Set the accttype attribute of the savAcct object to Savings
   savAcct.accttype = 'Savings';
   //Set the acctName attribute of the savAcct object to D.Castillo-Sav
   savAcct.acctName = 'D.Castillo–Sav';
   //Invoke the makeDeposit method with 220 as the argument
   savAcct.makeDeposit(220);
   //From the BankAcct class, instantiate an object named savAcct
   List<BankAcct> bankAccts = new List<BankAcct>();
   System.debug('The BankAcct List has ' + bankAccts.size() + ' bank accounts.');
   //Add the chkAcct object to the bankAccts list
   bankAccts.add(chkAcct);
   //Add the savAcct object to the bankAccts list
   bankAccts.add(savAcct);
   System.debug('The BankAcct List has ' + bankAccts.size() + ' bank accounts.');
   System.debug('Here is the list: ' + bankAccts);
   //Declare a list FOR loop that uses an iteration variable named tempacct
   //to loop through the bankAccts list
   for (BankAcct tempacct:bankAccts){
       system.debug(tempacct.acctName + ' is a ' + tempacct.accttype +
       ' account with a balance of $'+ tempacct.getBalance());
   }

   Copy
3. Verify that Open Log is selected and then click Execute. The execution log opens.
4. Select Debug Only.
5. Review the debug messages and then close the log.

In the createContact method, add a List FOR loop to iterate over a Candidate list.

1. In the CreateContactFromCan class, replace the existing code with this code:

   public with sharing class CreateContactFromCan {
       //Declare a method that returns void and accepts a Candidate list named candsFromTrigger
       public void createContact (List<Candidate__c> candsFromTrigger){
           //Instantiate a Contact list named conList
           List<Contact> conList = new List<Contact>();
           //Declare a list FOR loop that uses an iteration variable named currentCandidate
           //to loop through the candsFromTrigger list
           for(Candidate__c currentCandidate:candsFromTrigger){
           }
       }
   }

   Copy
2. Save the CreateContactFromCan class.
