So, first I have an ImagePanel public class ImagePanel extends JPanel { private Image img; public void setImage(String img) { setImage(new ImageIcon(img).getImage()); } public void setImage(Image img) { int width = t...

Would you be kind enough to explain what this method is doing? long TSBCA::GetSignedValue(const NDataString &value) { static NDataString s; s = value; long multiplier(1); size_t len(s.Len()); ...
Naively, I expected a ThreadLocal to be some kind of WeakHashMap of Thread to the value type. So I was a little puzzled when I learned that the values of a ThreadLocal is actually saved in a map in the Thread. Why was it done that way? I would expect that the resource leaks associated with ThreadLocal would not be there if the values are...

What's the best/preferred idiom for a decrementing for loop, and why? for(int idx=(len-1); idx>=0; idx--) {...} or for(int idx=(len-1); idx>-1; idx--) {...} or (based on sylvarking's answer, but using for to constrain the index scope) for(int idx=len; idx-->0; ) {...} Is one or the other more likely to trip up another developer?...
I'm trying to implement a binary protocol between a flash application and a Custom Java Server using TCP/IP sockets, the protocol's messages are of variable length, so my idea is to add a field indicating the number of bytes I have to read before parsing a complete message, something like this: bytesToRead = socket.readInteger(); var bf...
