I would use field + getter + maybe setter.

The advantages I see are:
A) The ability to have no setter which controls what can change
    the value
B) The ability to override getter and setter in sub classes
C) The ability to put more code in getter and setter

It is not much work to add the getters and maybe setters as
a modern IDE should be able to generate those.

If you don't like to see all these lines of code then
switch to Kotlin.
