Based on the SOP Knowldege 

Contact Management: Cumulus Cloud Confectioners’ best practice for contacts that have left a company is to update the customer status to ’No Longer at the Company’ and create a new record with the updated information. Additionally, upon creating a new record for the departed contact, it’s essential to generate a case to ensure seamless tracking of any follow-up actions or communications required with the new contact or associated accounts. This helps maintain comprehensive records and facilitates efficient customer relationship management.

We can mark the existing Candice Fluffington record status with 'No longer at Company'. Then create a new contact record with all infromation provided in the step then create a case from the new contact. 

I passed challenge 2 by doing the above steps.

Hi @Edward Dalton,

• You need to assign strings (In constructor, It should be strings not strList) to strings class variable. Use this keyword.
• You should replace strings = strList; with this.strings = strings;
• In constructor remove strings.iterator();

Code should be like this -

public class MyIterable implements Iterable<String> {
    private List<String> strings;
    public MyIterable(List<String> strings) {
        this.strings = strings;
    }
   public Iterator<String> iterator() {
      return strings.iterator();
   }
}

The output is as followed, indicating that everything ran ok. We even see the records in the output. But the submitting the challenge gives the message above. 

Here is the output:

Hi, @Kim Pat

Try to use this code:

Apex Class:

public class MyIterable implements Iterable<String> {
   Private List<String> strings;
  // Constructor to initilize the list of strings
  public MyIterable(List<String> strings) 
  {
   this.strings = strings;
   }
   // Implementing the iterator method
    public Iterator<String> iterator(){
    return strings.iterator();
    }
}

Test Class:

@IsTest
public class MyIterableTest {
      @IsTest
    static void testIterableForLoop(){
         // Create a list of strings
        List<String> strings = new List<String> {'Hello', 'World'};
       // Create an Instance of MyIterable
             MyIterable myIterable = new MyIterable(strings);
        // Use a for loop to iterate over the MyIterable instance
         for(String str: myIterable)
         {
           //Print each string to the debug log
            System.debug(str);      
         }      
    }
}

after saving Apex Class and Test Class click "Run Test".

Hello @R Pious Wilfred Nicholas, 

Try below code and it should work.

public class PropertyUtility{
    public static void newListedProperties(){
      List<Property__c>  newPropList = [Select Name,Days_On_Market__c,Broker__r.Email__c from Property__c where Days_On_Market__c < 31];
        for(Property__c p : newPropList){
         string  propEmail = p.Name +':'+ p.Broker__r.Email__c ;
            system.debug(propEmail);
        }
    }
}

Hope above information was helpful.

Hi , 

I had similar issues with the renew. 

here's what happened.....the culprit was whitespace in my case.

1) for every method incl. constructor 

write in this exact format (parenthesis immediately following method name + one space right before the curly brackets.)

methodname() {

}

2) put space around = 

//this didn't work

this.strings=strings;

//this worked

this.strings = strings;

this is so dumb.....

Try this one for the constructor and the sample code below should work: 

public class MyIterable implements Iterable<String> {
    private List<String> strings;
    public MyIterable(List<String> strings) {
        this.strings = strings;
    }
    public Iterator<String> iterator() {
        return strings.iterator();
    }
}

In case you need a Test Class: 

@IsTest
public class MyIterableTest {
    @IsTest
    static void testIterableForLoop() {
        List<String> strings = new List<String>{'Hello', 'World'};
        MyIterable iterable = new MyIterable(strings);
        for (String str : iterable) {
            System.debug(str);
        }
    }
}
