when should we use hasnext()

[sohan_snow]

Hi All,

I understand that hasnext() will either return true or false, but next() also in a way does the same thing and then goes to the next record.

I would like understand when should we use hasnext(), Is there any case scenario where usage of hasnext() is important

Thanks in advance

Let's say you want to know whether any results there for search criteria instead of getting the next object just use hasNext() if it returns true it means there is at least one result for your search criteria.

So fast not need to get the full object.

Please check: What's the difference b/w next() and hasNext()?

hasnext() should be used when you need to check if there are any records after you execute a query. If will stop after it finds a record and returns true/false.

next() should be used to iterate loop of records, it will execute until all records are iterated.It will return objects of records.
