Hey guys! This should be my last question for a while, thanks for all the help so far!

I dont think i understand how data is passed between Apex into the controller... I though you create a List of objects and and you store a query to make it display on the table

Here is my Apex:

public class controllerClass {
    public Case myCase {get; set;} 
    public List<Case> cases {get; set;} 
    public List<Account> accounts {get; set;} 
    public List<Case> cases2 {get; set;} 
    
    public controllerClass(ApexPages.StandardController stdController){        
        this.myCase = (Case)stdController.getRecord();   
        
        //Query Obtains the Accounts with open cases and displays them as a table in firstProject.vfp
        this.cases = [SELECT AccountId, Status, Subject FROM Case WHERE IsClosed = False ORDER BY AccountId DESC];       
    	
        //Query Obtains the Accounts with no cases
    	this.accounts = [Select Name FROM Account WHERE Id NOT IN (SELECT AccountId FROM Case)];
        
        //Query Obtains the 5 most recent cases
        this.cases2 = [SELECT Subject, CreatedDate FROM Case ORDER BY CreatedDate Limit 5];     
    }	
}

I think it the line this.case2 is completely wrong and it causing the issue... I dont think it is even transferring data... Could somebody help me fix it and also explain (or share a source) how the query information is actually being transfer into my visualforce page.

This is my VF page:

<apex:page standardController="Case" extensions="controllerClass"> 
    
    <apex:pageBlock title="Table of Accounts with Open Cases">
        <apex:pageBlockTable value="{!Cases}" var="c">
            <apex:column value="{!c.AccountId}"/>
            <apex:column value="{!c.Status}"/>
            <apex:column value="{!c.Subject}"/>
        </apex:pageBlockTable> 
    </apex:pageBlock> 
    
    <apex:pageBlock title="Table of Accounts with no Cases">
        <apex:pageBlockTable value="{!Accounts}" var="a">
            <apex:column value="{!a.Name}"/>
        </apex:pageBlockTable> 
    </apex:pageBlock> 
    
    <apex:pageBlock title="Table of 5 most recent cases">
        <apex:pageBlockTable value="{!Cases}" var="c">
            <apex:column value="{!c.Subject}"/>
            <apex:column value="{!c.CreatedDate}"/>
        </apex:pageBlockTable> 
    </apex:pageBlock> 
    
</apex:page>

The first two tables are correct. The last should display a table of the 5 most recent cases, however my program crashes when I attempt to preview this code I have shared.

Once again thanks for all the amazing support!
