From time to time, we all have to make some hard choices in life. Recently I went through just such a time, when I found myself with 3 different job-offers, that I had to act on relatively swiftly. Now admittedly, this situation belongs to the luxury category of problems, but none the less, it represented a serious decision making challenge to me. None of the jobs were perfect in all aspects (I don't believe such a job exist), so depending of the time of day, I would lean towards one of them, only to change my mind later on that very same day.

However, the dynamic proxy feature introduced with Java 1.3, does allow us to emulate duck typing. First a disclaimer though, I am far from the first to blog about the subject, even Brian Goetz (now Java's language architect) blogged about it back in 2005. Dynamic Proxy It was back in 2000 that Sun introduced the Dynamic Proxy functionality to JDK 1.3. As the name implies, it caters to the well known Proxy patt
