I'm writing an array-backed hashtable in Java, where the type of key and value are Object; no other guarantee. The easiest way for me code-wise is to create an object to hold them: public class Pair { public Object key; public Object value; } And then create an array public Pair[] storage = new Pair[8]; But how does the j...

If I add an a to every index, var_dump() will show double quotes around the key, my gu...
I am looking for a C++ data type similar to std::vector but without the overhead related to dynamic resizing. The size of the container will remain constant over its lifetime. I considered using boost::array, however, that is not appropriate because it requires the size of the array to be known at compile time, which is not the case in m...
