​​​​​​​I am unable to print array return by controller on VF page

Hi,
I am unable to print array return by controller on VF page:-
Controller:-
public with sharing class generateStringArray {
    public list<String> generateStringArray{ get; set; }
    public static list<string> getgenerateStringArray(){
        Integer n=10;    
        list<string> myarray=new list<string>();
        for(integer i=0;i<=n;i++){
            myarray.add('Test'+i);
        }
        return myarray;
    } 
}

VF page:-
<apex:page Controller="generateStringArray" showHeader="true" sidebar="false">
    <h1>List</h1>
    
        <apex:repeat value="{!generateStringArray}" var="string" id="theRepeat">
        <apex:outputText value="{!string}" id="theValue"/><br/>
        </apex:repeat>

  
</apex:page>

Use this
  
public with sharing class generateStringArray {
    public static list<string> getGenerateStringArray(){
        Integer n=10;    
        list<string> myarray=new list<string>();
        for(integer i=0;i<=n;i++){
            myarray.add('Test'+i);
        }
        return myarray;
    } 
}
  
<apex:page Controller="generateStringArray" showHeader="true" sidebar="false">
    <h1>List</h1>
    
        <apex:repeat value="{!generateStringArray}" var="string" id="theRepeat">
        <apex:outputText value="{!string}" id="theValue"/><br/>
        </apex:repeat>

  
</apex:page>
