Last week, we had the author of TDD for a Shopping Website LiveProject. Friday at 11am Ranch time, Steven Solomon will be hosting a live TDD session just for us. See for the agenda and registration link
Dear All, I have a 40 java bean each with about 20 -30 different get and set methods. I want to get the names and values of all the methods in one bean at a time . And then reformat that data.Is there any thing similar to jdbc getMeataData where you get column name s and it's values. I want to avoid writing 20-30 getProperty statements. Any help is highly appreciated. Thanks, peter
Sounds like reflection. Check out myBean.getClass().getMethods() which will return an array of java.lang.reflect.Method objects representing all the public methods defined in myBean. You can then walk thru them and test their names, parameters, return types, etc. You can even use method.invoke() to run the methods. Check out Sun's reflection tutorial http://java.sun.com/docs/books/tutorial/reflect/index.html
You can also download the Beanbox prototype tool from Sun. It has a Report feature that not only lists all the property-oriented methods in a Bean, but also groups the listings between Properties, Event Sets, and other methods. It also tags expert options and a few other things. It's part of the BDK which is available here.
