> Unfortunately, this conflicts with the (common, good) advice to make as many variables final / const as possible, since it separates the declaration of a variable and its assignment. In Java you can separate the declaration and assignment of a final variable as long as every branch provably assigns to the variable. For example: final int x; if(someCondition) { final int a = 1; final int b = 2; x = a + b; } else { x = 0; }
