We would like to tell TeamCity to look for a new type of bug that developers might introduce that has to do with the usage of == vs .equals For a particular type within the system we were using == to do c...
I prefer buttons with minimal margins, about as wide as their text caption. Is there a way to achieve that in a JButton in Swing? What I am seeing in practice now is that even if I try to use setMaximumSize() and similar, it just ends up eating the text caption, cutting it off to the right. But it does not reduce the margins. ...

The simple code looks like this: public class ShortestPath { public static void main(String[] args) { int x = Integer.MAX_VALUE; int [][] adj= { {0, 6, x, 6, 7}, ...
As I read in Thinking in java, Interface and inner class provide more sophisiticated ways to organize and control the objects in your system. C++, for example, does not contain such mechanisms, although the clever programmer may simulate them. Is it true that C++ programmer simluate features that java owns,e.g. interface ...
I have a class CustomerBean { Customer customer; public CustomerBean() {...} public getCustomer() {...} public void setCustomer(Customer c) {...} ... } When using normal JSF I can use a setPropertyLIstener tag (on say a commandLink) to update the customer property.
