Get the second level domain of an URL (java)

Question

I am wondering if there is a parser or library in java for extracting the second level domain (SLD) in an URL - or failing that an algo or regex for doing the same. For exam

Answer 1

1.

Method nonePublicDomainParts from simbo1905 contribution should be corrected because of TLD that contain ".", for example "com.ac":

input: "com.abc.com.ac"

output: "abc"

correct output is "com.abc".

To get SLD you may cut TLD from a given domain using method publicSuffix().

2.

A set should not be used because of domains that contain the same parts, for example:

input: part1.part2.part1.TLD

output: part1, part2

correct output is: part1, part2, part1 or in the form part1.part2.part1

So instead of Set use List.
