what is the difference between these initializations? class A { private int i; { i = 67; } } and class A { private int i = 67; }

Answer 1

The first one is an initializer block. The Java compiler will copy initializer blocks into every constructor. Therefore, this approach can be used to share a block of code between multiple constructors.

The second one is an initial value for a field in its declaration.
