A java list can be converted to a String in Scala by utilizing toString 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.
[5, 6, 7]
Therefore, a String is returned. Here, firstly a list is created where, the int elements are added to it utilizing add method. After that toString method is utilized in order to convert the stated list to a String.
[5, 4, 6]
It is same as above example but here the proper order of the list is not maintained so, the output obtained is also not in a proper order.
