Java equivalent of C# 'using' statement
I'm transitioning from C# to java, so please bear with me... When reading a file in C#, you simply wrap it all in a big 'using' block, so that if you have an exception, the file will still be closed.

How big is performance decrease of compiling when there are not necessary USINGs?
Hi, I'm just curious if unnecessary USINGs in my code slows down compiling of Visual Studio solution.

Determine if code called from an exception handler (using statement)?
I want to do something mildly silly. In my Dispose() method for an object, I want to print a debug trace for the object, telling me all events which happened while it was alive.

what is the expected behavior?
Below is a purely academically invented class hierarchy. struct X{ void f1(); void f2(); void f3(); }; struct Y : private X{ void f4(); }; struct Z : X{ }; struct D : Y, Z{ using X::f2; using Z::X::f3; }; int main(){} I expected using declaration for X::f2 to be ambiguous as 'X' is a...
