of any static initializer blocks, and that non-static final fields are initial-
ized by the end of all construction paths for an object. A compile-time
error will occur if the compiler cannot determine that this happens.
Blank final local variables are useful when the value to be assigned to

field or other variable was intended. Issues regarding when you should,
