I'm trying, and failing, to retrieve all Enum values and place them in a list using Java 8 and streams. So far I've tried the two approaches below, but neither one returns the value.
I want to fully understand how a C++ compiler deals with an enum exceeding the largest possible number, i.e., containing -1 and UINT64_MAX the at the same time, i.e.
I have the following interface:that is implemented by my enums (I omitted the constructor and methods implementation)
I want the user to enter a number from 1 to 7. If the number is 1, print that it is a Monday. If the number is 2, print that it is Tuesday, etc.
I have an enum with descriptions as String. This is the enum.Now, if I need the data for A, I'd just do
Let I be some integral type. Now suppose I have a enum class my_enum_class : I, with values which may not be consecutive. And now I get some I value. How do I check whether it's a value enumerated in my_enum_class?

For such code:clang (linux/7.0.0) reports no errors [-c -std=c++11 -pedantic], but gcc (linux/8.2.1) doesn't compile it:
This question already has an answer here:I'm currently working on a Dungeon game project which is composed of multiples rooms connected to each other.
While looking at the source code of the Comparators class, I came across these lines of code.I think I understand what this does. It's a Singleton instance which implements the Comparator interface. It uses the "compareTo" of classes that implement the Comparable interface for natural ordering (please correct me if...
