A java Set of strings 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.
Therefore, a set of strings 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 string elements of the Set to the stated set one after another and then prints the results.
