As a side note, 'checked' and 'unchecked' are keywords in C# that have to do with explicitly checking for arithmetic and conversion overflows: http://msdn.microsoft.com/en-us/library/74b4xzyw.aspx

I'm assuming you are a Java dev trying out C#, otherwise I don't understand your questions (if so can you clarify, or you might need to change the tag from "C#" to "Java"!).

You'll be saddened (or delighted!) to learn C# doesn't have the equivalent of checked an unchecked exceptions. All exceptions in c# are like Java unchecked exceptions.
Here[^] is a comparison between Java and C#. Some if it is a little out of date (IMO C# drew level with Java at v2.0, and overtook at 3.0) but the most of the comparisons are good, if a little Java Biased :-).
