Program to convert Java list to Traversable in Scala
A java list can be converted to a Traversable collection in Scala by utilizing toTraversable 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.
Buffer(5, 6, 7)
Therefore, a Buffer of integer is returned. Here, firstly a list is created where, the int elements are added to it utilizing add method. After that toTraversable method is utilized in order to convert the stated list to a Traversable collection.
Buffer(3, 1, 2)
It is same as above example but here the stated list is not in the proper order and the collection returned is also not in proper order.
