  Tutorial: Practically Groovy: Smooth operators

The Java? language has banned operator overloading, but upstart Groovy says \"bring it on!\"

Tutorial Details:

Find out what you\'ve been missing all these years, as Andrew Glover walks you through everyday uses of Groovy\'s three categories of overloadable operators in this final, regular installment of Practically Groovy.
Many developers who started out using C++ will admit some nostalgia for overload operators such as + and -. Convenient though they are, the polymorphic nature of overridden operators can cause confusion, so operator overloading has been banned from the Java language. The upside of this limitation is clarity: Java developers never have to wonder if the + on two objects adds them together or appends one object to another. The downside is the loss of a valuable shorthand.
