Program to print Java Set in Scala
A java Set 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 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 elements of the Set to the stated set one after another and then prints the results.
[2, 5, 6]
It is same as above example but here one more element is added in the stated set and as it is a set so, the order of the elements is maintained.
