Resources on direct translation of GOF example

I am studying GOF book, found it's the best book in the market, after viewing a few other design pattern books. However, I don't know C++, and it would be too time consuming just to learn C++ to study design pattern. Therefore, I am looking for Java translation of the GOF C++ examples(C# might be OK, too). The reason is that there're so many Java implementation are on Internet, however, I can't know for sure if they misuse them, also they lacks of details as the original book.
