...
No.
The compiler will generate a separate finally block for each variable.
The spec (§8.13) says:
When a resource-acquisition takes the form of a

Get timezone from DateTime
...mezone information. It may know if it's UTC or local, but not what local really means.
DateTimeOffset is somewhat better - that's basically a UTC time and an offset. However, that's still not really enough to determine the timezone, as many different timezones can have the same offset at any one po...
Difference between a Seq and a List in Scala
...tional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector is a better choice than List, but habit is hard to break.
Seq is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually t...
What's the simplest way to list conflicted files in Git?

Why is the JVM stack-based and the Dalvik VM register-based?
...s for instructions

is important if you're going to be
downloading the code over a slow
network link.
Going with a register-based scheme probably means that Dalvik's code generator doesn't have to work as hard to produce performant...
Why is there no GIL in the Java Virtual Machine? Why does Python need one so bad?
I'm hoping someone can provide some insight as to what's fundamentally different about the Java Virtual Machine that allows it to implement threads nicely without the need for a Global Interpreter Lock (GIL), while Python necessitates such an evil.
