Property Binder has company

One of the things about JOpt Simple about which I feel most proud is the fact that I advertise alternatives to it on the project's website. I realize that choices abound for command line option parsing in Java; before...

Richer Java runtime type info with javaRuntype

By now you surely know that Java's generics info is erased from objects during compilation. For example, given an object whose runtime class is java.util.List, I cannot tell at runtime whether the object was originally a List<Integer>, or a List<String>,...

Pronouncing wildcarded Java generics expressions

I've taken to pronouncing the Java generics wildcard character as "huh?".  So that:

Agile with a capital "A"

Nice idiom for uninstantiable Java classes
