Create and Adjust the List

Instantiate a list named bankAccts and add the two BankAcct objects to the list.

1. 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 savAcct
   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 List class, instantiate a BankAcct List object named bankAccts
   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);

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, instantiate a Contact List object and accept a Candidate List object named candsFromTrigger as the argument. 

1. In the Developer Console, open the CreateContactFromCan class and 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>();
       }
   }

2. Save the CreateContactFromCan class.
