Trie data structures - Java

Question

Is there any library or documentation/link which gives more information of implementing Trie data structure in java?

Any help would be great!

Thanks.

Solution 1

You could read up on Java Trie or look at trie.

Solution 2

There's a java implementation in Robert Sedgewick's book on algorithms. It's very basic, i.e., no compression and a very simple interface, but I found it instructive to understand how tries work.

I also recently found a library that includes a memory efficient concurrent implementation of tries which looks very promising. It even includes a LCS solver using tries.

There is also the Lucene implementation that's used in production applications.

Solution 3

Another implementation, I believe from Limewire developers originally: https://github.com/rkapsi/patricia-trie
