How can I pass the a number obtained in Apex and display it in Visualforce?

I need to pass a number from my Apex Class into my visualforce page.

This is my Apex Class: 
public class controllerClass {
    Public Case myCase {get; set;} 
    public List<Case> cases {get; set;}    
    
    List<Case> openedCases = [SELECT AccountId, Status, Subject FROM Case WHERE IsClosed = False ORDER BY AccountId DESC];
    
    Public controllerClass(ApexPages.StandardController stdController){        
        this.myCase = (Case)stdController.getRecord();        
        this.cases = openedCases;     
    }	
    
	//This is the integer I want to pass into visualforce
	Integer temp = openedCases.size();
	
    
}

This is my Visualforce page:
  
<apex:page standardController="Case" extensions="controllerClass"> 
    
    <apex:pageBlock title="Table of 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> 
    
    <!-- Variable should go below-->
    <apex:variable var="" value="" />
    <p>The number from apex is <!-- Apex Number -->.</p>

        
</apex:page>

    <p>The number from apex is {!cases.size}.</p>

Instead of that integer you can directly get the size like above.


If you want to use integer number then:
  
public class controllerClass {
    Public Case myCase {get; set;} 
    public List<Case> cases {get; set;}    
    
    List<Case> openedCases = [SELECT AccountId, Status, Subject FROM Case WHERE IsClosed = False ORDER BY AccountId DESC];
    
    Public controllerClass(ApexPages.StandardController stdController){        
        this.myCase = (Case)stdController.getRecord();        
        this.cases = openedCases;    
    }	
    public Integer temp
{ get{return openedCases.size();}
set;}
	
	
    
}

Use this temp in page.

Thanks! But I just used the size of openedCases as an example. How would I transfer say a hardcoded number? I want to know for every situation, not just this one example.

Hi Francisco,
If you need hardcoded value in you vf page then assign value in constructor.Try like below code 
public class controllerClass {
    Public Case myCase {get; set;} 
    public List<Case> cases {get; set;}    
    public integer temp{get;set;}
    List<Case> openedCases = [SELECT AccountId, Status, Subject FROM Case WHERE IsClosed = False ORDER BY AccountId DESC];
    
    Public controllerClass(ApexPages.StandardController stdController){        
        this.myCase = (Case)stdController.getRecord();        
        this.cases = openedCases;     
    }	

  public controllerClass(){
		temp = HARDCODED NUMBER;
		}  
}
If you need dynamic then @Nayana K is right.
Please mark it solved.
Thanks
Hemant
