Method next() returns the next element in the collection.Note: In this example, we will create/declare an iterator by specifying Integer type - which is base type of the List and then the methods next() and hasNext() will be called through Iterator object....

Before java 8, if you had to iterate on a java collection then your would get an iterator instance and call it’s next method until hasNext() returns false. This is common code and have been used thousands of time in day to day programming by us. Syntax is also always same. So can ...
