MongoDB hasNext() and next() Example

Date: 2018-03-09

This tutorial explains MongoDB's hasNext() and next() methods used to iterate through query results. hasNext() returns true if more documents exist in the cursor, and false otherwise. next() retrieves the next document; throwing an exception if no more documents are available. The tutorial provides examples of using these methods with and without query criteria, demonstrating how to check for the existence of further results and how to retrieve them one by one.
