CityHash64 for Java

[Paul Meehan]

Hi

I am interested in an equivalent algorithm in Java for CityHash C++. By equivalent I mean a 64 bit signed long returned by a Java version will be equivalent to the uint64 returned by the C++ version after conversion/adjustment. A Java version is to be found here:

https://github.com/tamtam180/CityHash-For-Java

But after testing the 64bit hashing function (CityHash64), the hash values returned are different when the same strings are inputted into both C++ and Java.

Can anybody comment or shed some light on this?

thanks
Paul

Although it may not answer your question directly, it appears as if there is a java implementation in the guava libraries:
