class S mutable static int i; // err mutable static int j; // err static int k; // Alright, all circumstances share a similar member

It is also mandatory to assign a value to them at some time of declaration otherwise it will give an error during compilation of the program snippet. That is why it really is also referred to as a compile-time constant.

In case you are Doubtful of whether or not the value will transform, but you don't want other courses or code to have the ability to change it, use readonly.
