java - Check whether there are remaining items in the List while iterating -

i'm doing bean validation list of conditions:

public abstract class basemyconditionvalidator<t extends annotation> implements constraintvalidator<t, list<mycondition>> {      @override     public void initialize(t constraintannotation) {}      @override     public boolean isvalid(list<mycondition> conditions, constraintvalidatorcontext context) {         boolean result = true;         if (!conditions.isempty()){             int = 0;             (mycondition cond : conditions){                 if (cond.getjoinpart() != null){                     if (!hasnext(i, conditions)){                         return false;                     }                 }                 i++;             }         }         return result;     }      private boolean hasnext(int index, list<mycondition> conditions){         try {             conditions.get(index + 1);         } catch (exception e){             return false;         }         return true;     }  } 

my question is there simpler approach deal with:

• checking if there still item next in line during iteration of list

you use plain old iterator iterate through list, or instead of hasnext(i, conditions) check list length (i < conditions.size() - 1)

in end, instead of iterating through whole list, check if last element's joinpart null (at least doing)

@override public boolean isvalid(list<mycondition> conditions, constraintvalidatorcontext context) {     return conditions.isempty() || conditions.get(conditions.size() - 1).getjoinpart() != null; }
