Question

If I am naming a new class in an OOP language, which is a better convention:

1. XMLWriter
   • Most common
2. XMLwriter
   • Easier to distinguish
3. XmlWriter
   • No longer an acronym
4. XML_Writer
   • Removes the point of camel case

Pedantic yes, but I’m curious who uses what and why.

Answer 1

Java conventions seem lately to favor treating well-known acronyms like words, so: “XmlWriter”…

But nobody seems to be very consistent. Take JavaScript’s XMLHttpRequest for example. What a trainwreck!
