A java list 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 else an error will occur.
Now, lets see some examples and then discuss how it works in details.
Therefore, a non-empty iterator is returned. Here, firstly a list is created where, the int elements are added to it utilizing add method. After that toIterator method is utilized in order to convert the stated list to an iterator.
It is same as above example but here an empty iterator is returned as here the stated list is empty.
