Answer 1

Hashset doesn't maintain the order of insertion in the output so I have passed it to an ArrayList to achieve the same. If the order doesn't bother you then you can print the Hashset directly in the main method.

Answer 2

Simple output to console:
System.out.print(string) or
System.out.println(string).

For real world applications you'd use a logger.

Answer 9

stephen haokip actually you don't have to create that in this scenario. But just in case you want to perform some other operations on the map then you might need to create a new one.

It is just like calling a method which returns a value of some type and we store it in the same type variable so that it could be manipulated later in the code.
