C# have records which provide immutability and equality testing. [1] The record is sealed to prevent inheritance. [2] It overrides the built-in ToString() method. [3]This example implementation includes a static method which can be used to initialize a new instance with a randomly generated globally unique identifier (GUID).

In software engineering, the multiton pattern is a design pattern which generalizes the singleton pattern.Whereas the singleton allows only one instance of a class to be created, the multiton pattern allows for the controlled creation of multiple instances, which it manages through the use of a map.

Illustration. Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.
The expression ((Integer) 42). toString will convert an integer literal to string in Java while 42. ToString performs the same operation in C#. This is because the latter one is an instance call on the primitive value 42, while the former one is an instance call on an object of type java.lang.Integer.
