Weird “[]” after Java method signature
...point out that a similar (but not identical) notation is possible in C and C++:
Here the function f returns a pointer to an array of 10 ints.
int tab[10];
int (*f())[10]
{
return &tab;
}
Java simply doesn't need the star and parenthesis.

Can I call an overloaded constructor from another constructor of the same class in C#?
... could do this with a common initialization function (like you would do in C++ which doesn't support ctor chaining)
class A
{
//ctor chaining

public A(int i)
{
Init(i);
}
// what you want
public A(stri...

Subclassing a Java Builder class

Ah, I didn't know that, as I come from a C++ background. That's a useful approach for this small example, but with a full-blown class repeating all the methods becomes a pain, and an error-prone pain at that. +1 for teaching me something new, however!

Yes it is a standard macro with the semantic "Not Debug" for C89, C99, C++98, C++2003, C++2011, C++2014 standards. There are no _DEBUG macros in the standards.
