List list = new ArrayList();
while (rs.next()){
String [] row = String[3];
row[0] = rs.getString(1);
row[1] = rs.getString(2);
row[2] = rs.getString(3);
list.add(row);
}
The second method then iterates the results, performs some calculations, and inserts new values to database:
for(int i = 0; i < list.size(); i++){
String[] row = (String[])list.get(i); // yaaggghhhhhh!?!
....
}
Smells like C... Personally I have nothing against C, but not inside Java code. I'd better introduce a bean class to encapsulate the values.
OK. let it be:
// as all the logic fits into one class i'd better make this class private
private class MyBean {
String a;
String b;
String c;
MyBean(String _a, String _b, String _c){
a = _a; b = _b; c = _c;
}
}
What I realized now - no point of having getters and setters for the inner class' members. Why?
1) This is used only inside the host class, thus no encapsulation needed.
2) Getters and setters will just flood the source code without bringing any value and making the code less readable.
Instead, I set default access to the bean class members.
The moral is that getters and setters aren't absolutely necessary for simple code. I believe this is trivial, but some people wouldn't agree I guess.
Take care :)
