Why not inherit from List?
...dd, Remove, etc.) to be overridden because they are virtual. List<T> does not.
The last part of your question is spot on. A Football team is more than just a list of players, so it should be a class that contains that list of players. Think Composition vs Inheritance. A Football team has a lis...
How to create a memory leak in Java?
...ass → static ThreadLocal field → ThreadLocal object.
(The ClassLoader doesn't really play a role in creating the leak, it just makes the leak worse because of this additional reference chain: example class → ClassLoader → all the classes it has loaded. It was even worse in many JVM implemen...
Templated check for the existence of a class member function?

Also, stack vs. heap is not only a perform...

Why are mutable structs “evil”?
...grammer just thinks that it might be in the future. For example, it simply doesn't make sense to change a date. Rather, create a new date based off the old one. This is a cheap operation, so performance is not a consideration.
