> ``` > When to use a final variable : > > The only difference between a normal variable and a final variable is that we can re-assign value to a normal variable but we cannot change the value of a final variable once assigned. > Hence final variables must be used only for the values that we want to remain constant throughout the execution of program. > ``` The above states that we must use `final` if we don't want variables to change. And though the `only` might imply that we must *not* use it otherwise, this is false. It is a soicial issue/dethat fensive programming to use final so that people have to make a conscious decision that change is allowed. > In addition, the indiscriminate use of FINAL makes it difficult to create unit tests which indeed would be a reason to make vars not final at times. > I would appreciate it immensely if you could technically explain to me why we use FINAL in this (incorrect) way throughout the project. as said above; social/defensive. The reasons only becomes technical when mistakes have been made. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
