Question : ID3 algorithm implementation in JAVA or c++

hello ,

i'm searching for an implementation of the ID3 algorithm in java(or c++) to use it in my application , i searched a lot but i didn't find anything !
i have for example the following table of decisions:

low high high : buy
high high low : dont buy
low low high : dont buy
high high low : buy    
...

i want to feed the ID3 function new attributes (lets say "low high low"), and the output will be the decision (buy or dont buy)
anyone knows of a general ID3 implementation anywhere ?

Thank you in advance.
