Question about var initialization... 2006-10-18 - By Vadim Vera

Hi list, my question isn't J2EE related...
I'm wondering if the vars initialization (class and instance vars) is for
consistency (I know Java has initialization rules when var creation take
place) or just a type-style; for example, I've analyzed code from some sites
(Oracle samples, IBM, Apache, TheServerSide.com) and they initializes the
vars in some classes and in others not...it's just a "make sure" question...
Example 1:
// imports ommited
class Some {
private List list = new ArrayList();
Some() {
}
}
Example 2:
// imports ommited
class Some {
private List list;
Some() {
list = new ArrayList();
}
}
One initializes on declaration, the other inside constructor, I don't know
the difference; I must say I prefer the first one. Thanks in advance...
