How to check if a char is equal to an empty space?
...aracter and a String, but char and String are not comparable and cannot be cast to a common base type.
There is such a thing as a Comparator in Java, but it is an interface not a method, and it is declared like this:
public interface Comparator<T> {
public int compare(T v1, T v2...
Avoiding an ambiguous match exception
... of parameters and same types of parameters. I'm thinking here of explicit cast operators overloads. For example public static explicit double(MyType obj) and public static explicit float(MyType obj). You will still have an AmbiguousMatchException. In this case, you could use returnType.GetMethods()...
Detecting endianness programmatically in a C++ program
... guaranteed to be correct. gcc prefers this compared to the direct pointer cast.
This is also much better than fixing the endianness at compile time - for OS which support multi-architecture (fat binary on Mac os x for example), this will work for both ppc/i386, whereas it is very easy to mess thin...
Give examples of functions which demonstrate covariance and contravariance in the cases of both over
...er appears is the return type from the next method, so it can be safely up-cast to T. But if you have S extends T, you can also assign Iterator<S> to a variable of type Iterator<? extends T>. For example if you are defining a find method:
boolean find(Iterable<Object> where, Objec...
Choosing the default value of an Enum type without having to change values
...value of (Staus) 0. The latter is valid to write directly, as enums can be cast to integers, but it will fail during deserialization, as the framework makes sure that an enum is always deserialized to a valid member. Your code will be perfectly valid if you change the line New = 10 to New = 0.

jQuery SVG, why can't I addClass?
...VGAnimatedString { baseVal="test svg", animVal="test svg"}
If we were to cast that SVGAnimatedString object to a string as jQuery does, we would have [object SVGAnimatedString], which is where jQuery fails.
How the jQuery SVG plugin handles this:
The jQuery SVG plugin works around this by patching...
How do I read an entire file into a std::string in C++?
... @DevSolar Well, the more legible version is ~30% shorter, lacks a cast and is otherwise equivalent. My question therefore stands: "What's the point of making it a oneliner?"

Reading my own Jar's Manifest

You can then cast it and call findResource() which has been known - for applets, at least - to return the needed manifest directly:
