Is it possible to rename a non-`final` variable to a `final` name style or the other way around in Eclipse?

Question

in Java, non- final variables use the naming convention of an uppercase for every first letter of a word: myInteger .
final variables use all uppercase letters and an underscore for word separation: MY_INTEGER .

In Eclipse, one can rename a varialbe using Alt + Shift + R and that takes care of all references. My question is: is there a way to easily rename a varialbe between the final and non- final styles. Otherwise, I need to retype more or less the whole name.

Answer 1

If I understand your question correctly this is what you are expecting: an automatic way of changing the coding style of a name used for a variable (I'm skipping the word final deliberately, because final means its value can't be changed and thus not a variable). That is, MY_INTEGER to myInteger and vice versa . If that's correct then I think the answer is no in Eclipse.

Answer 2

You can use the "rename" refactoring feature of the IDE to change the variable name. You cannot change the "style" of a name in Java because that is not a Java concept. What you change is the name of the variable.

Also, you don't use uppercase-plus-underscore names for final variables, you use them for constant variables, or by extension, final references to immutable objects. final references to mutable objects use camel case with an initial lower-case letter. Not all final variables are constants.
