Jaro winkler similarity on Empty strings

[santhosh6328]

I am using jaro wrinkler similarity to check similarities between names. In one of the use case, i found this issue.
s1 = "SOME NAME" - s2 = "" -> similarity = 1
Why is the output "1". shouldn't "1" be for exact matches ?
please help

version details : java-string-similarity -> 2.0.0

Can you attach your source code? I tried similarity for those strings, and it returned 0 (correct). Perhaps you mixed similarity with distance. Those are completely different things.

        System.out.println("Similarity: " + jw.similarity("SOME NAME", ""));
        System.out.println("Distance: " + jw.distance("SOME NAME", ""));

Also note that this scenario is covered via unit tests (see the NullEmptyTests class and its usage in the Jaro Winkler unit tests).
