A java list of characters can be returned from a Scala program by writing a user defined method of Java in Scala. Here, we don’t even need to import any Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples.
[g, f, g]
Therefore, a list of characters is returned from a Java method. Here, we don’t need to import any object of Scala. In the above program a Java method is written in Scala program. Where, this method adds the characters elements of the list to the stated list one after another and then prints the results.
[l, m, n]
It is same as above example but here one more element is added in the stated list and here proper order of the elements is not required.
