A java Set can be converted to an iterator in Scala by utilizing toIterator method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples and then discuss how it works in details.
Therefore, a non-empty iterator is returned. Here, firstly a set is created where, integer elements are added to it utilizing add method. After that toIterator method is utilized in order to convert the stated set to an iterator.
It is same as above example but here there are no elements in the stated list. So, here an empty iterator is returned.
