[SalesForce] System.ListException: List index out of bounds: 1 in apex share

I am getting below error and not sure how to fix that ?

List<Case> csList = [Select Id,OwnerId, (select Id, OwnerId, CreatedById from Payment__r), 
                     (select Id,OwnerId,CreatedById from Payment_2__r) 
                     FROM Case 
                     WHERE Id IN ('XXXXX')];
System.debug('------------------------------------@@ : '+csList); 

for(Case c : csList){
    List<Payment__c> siList = csList[0].Payment__r;
    System.debug('======= '+siList);
    List<Payment_2__c> siList2 = csList[1].Payment_2__r;
    System.debug('======== '+siList2);
}

Getting below error:

System.ListException: List index out of bounds: 1

Don't index in unless you are sure there are adequate members in the collection. If it were empty, you would be getting the 0 index out of bounds instead. Make sure you check the size.

List<Payment__c> collection1, collection2;
if (csList.size() > 0) collection1 = csList[0];
if (csList.size() > 1) collection1 = csList[1];

Per your code above, only a subset of the req.accounts records actually get added to the accList (in the ELSE statement).

As such, you need to modify the for loop at the end to use a List that mirrors accList but contains the AccountWrapper objects instead of Accounts (in order to access the Contact records on that custom APEX class).

There is just a small logic issue with your code. you are updating variable I before IF statement(adding the index number to deleteIndex list), that results into setting incorrect index. the variable I should be incremented after adding the index number to deleteIndex list. try below code-

    /*Method to remove contacts*/
   public void removeContacts(){ 
   ID removeThis = ApexPages.currentPage().getParameters().get('selectID'); 
   List<Integer> deleteIndex = new List<Integer>();
   Integer I = 0;
   deleteIndex.clear();
   for(selectedRecord deleteRecord : selectedContactValues){    
       if(deleteRecord.thisContact.id == removeThis){
           deleteIndex.add(I);
           system.debug(removeThis+'..................This record is deleted');
       }
       I++;  
     }
   for(Integer index  : deleteIndex){
       selectedContactValues.remove(index);
     }
   }
