Calendar.set(int year, int month, int date)
final Calendar a = Calendar.getInstance( ); a.set( 2009, 10, 16 ); System.out.println( a.getTime( ) );
-> Mon Nov 16 14:21:33 EST 2009
Apparently, month field in Calendar object is 0-based .

Should entities have behavior? or not?
Why or why not?
If not, does that violate Encapsulation?

A "Business Entity" is a modeling of a real world object, and it should encapsulate all of the business logic ... .
I do case they should have behavior.
If you're strictly following MVC, your model (entities) won't have any inherent behavior.

I have used cakePHP 1.2 and know how to use behaviors in it.

after a little googling i have come to believe...

When I was doing my early developing, I wrote a behavior and realized that behaviors didn't start by importing/declaring the behavior I'm interested in.

In C++ there are a lot of ways that you can write code that compiles, but yields undefined behavior (Wikipedia) . Is there something similar in C#? Can we write code in C# that compiles, but has undefined behavior?

However in Unsafe code, undefined behavior I believe is possible/library/aa664771%28VS.71%29.aspx
Has an example ....
Looking at the Wiki, the situations in which undefined behavior happens are either not allowed or throw an exception in C#.

Is it acceptable for an API to have bad behaviors (like segfault, bus error, memory leak) if the condition that would cause the bad behaviors is documented? Or should it always fail "gracefully" in all known conditions?
Answer Snippets (Read the full thread at stackoverflow):
It's called undefined behavior (link) , but you should.
Yes?? ;)
Absolutely.

I have a series of behaviors I want to enable/disable based on bit values. For example, the status of Behavior "A" is 0 or 1, Behavior "B" is 0 or 2, Behavior "C" is 0 or 4, etc. If the value of the variable containing the status is "5", I know Behavior...

Answer Snippets (Read the full thread at stackoverflow):
If you want to manipulate individual bits in an int variable directly, you can use bitwise operators:
Check whether i-th bit is set or not: bool isSet = (variable & ... .
They abstract away bit manipulation from you.
You can use a BitVector32 or BitArray.

Turns out many innocently looking things are undefined behavior in C++. For example, once a non-null pointer has been delete 'd even printing out that pointer value is undefined behavior .
Now memory leaks are definitely bad. But what class situation ...

There....
Memory leaks.
The behavior of memory leaks crash will occur.
Undefined behavior means, what will happen has not been defined or is unknown.
Expand that repertoire of behaviors so you can call it by its proper name: a bug.

An example of unspecified behavior in the C language the the order of evaluation of arguments to a function. It might be left to right or right to left, you just don't know. This would affect how foo(c++, c) or foo(++c, c) gets evaluated.
What other unspecified...

Be sure to always initialize your variables before you use them! When I had just started with C, that caused me a number of headaches .
