I am getting ready for a java certification exam and I have seen code LIKE this in one of the practice tests:
class Foo {
int x = 1;
public sta

Normally, you would put code to initialize an instance variable in a constructor. There are two alternatives to using a constructor to initialize instance variables: initializer blocks and final methods. Initializer blocks for instance variables look just like static initializer blocks, but without the static keyword:
{ // whatever code is needed for initialization goes here }The Java compiler copies initializer blocks into every constructor. Therefore, this approach can be used to share a block of code between multiple constructors.
You may also wanna look at the discussions here.
