- c++ - When should static_cast, dynamic_cast, const_cast, and . . .
The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<> () and dynamic_cast<> () to potentially dangerous casts like const_cast<> (), where const modifier can be removed so the const variables can be modified and reinterpret_cast<> () that can even reinterpret integer values to pointers
- Casting a number to a string in TypeScript - Stack Overflow

- Safe casting in python - Stack Overflow

- Casting variables in Java - Stack Overflow
Casting in Java isn't magic, it's you telling the compiler that an Object of type A is actually of more specific type B, and thus gaining access to all the methods on B that you wouldn't have had otherwise You're not performing any kind of magic or conversion when performing casting, you're essentially telling the compiler "trust me, I know what I'm doing and I can guarantee you that this
- Regular cast vs. static_cast vs. dynamic_cast - Stack Overflow
Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type dynamic_cast Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy) dynamic_cast (expression)
