... type twice for no reason
if (randomObject is TargetType)
{
TargetType foo = (TargetType) randomObject;
// Do something with foo

Not only is this checking twice, but it may be checking different things, if randomObject is a field rather than a local variable. It's possible for the "if" t...
What's the difference between getRequestURI and getPathInfo methods in HttpServletRequest?

For example if Servlet 'Foo' is mapped to URI '/foo' then I would have thought the URI:

How do I check if a C++ std::string starts with a certain string, and convert a substring to an int?
...
You would do it like this:
std::string prefix("--foo=");
if (!arg.compare(0, prefix.size(), prefix))
