Using Google Alerts, I found a nice, short review of DrJava on a blog called “Return to Java”:
Dr.Java is an interesting little IDE that helps newcomers develop Java code. Although aimed at newcomers, it seems to have lots of advanced features. It could be a useful alternative to the larger IDEs like Eclipse and NetBeans.
I found it useful to create small projects and play around with compiling and easily interacting with Java code, without the hassle of creating a large project in a full featured IDE.
Thank you kindly!
