Which operator is used to check the object has the specified type?
instanceof”
The java “instanceof” operator is used to test whether the object is an instance of the specified type (class or subclass or interface). It is also known as type comparison operator because it compares the instance with type.
What are complex objects?
Complex objects are the objects that are built from smaller or a collection of objects. For example, a mobile phone is made up of various objects like a camera, battery, screen, sensors, etc. In this article, we will understand the use and implementation of a complex object.

How do I compare two objects in a class?

How to get the type of a variable in C11?
Getting the type of a variable is, as of now, possible in C11 with the _Genericgeneric selection. It works at compile-time. The syntax is a bit like that for switch. Here’s a sample (from this answer):
How does the CLR determine if two reference types are equivalent?
At the point when you look at two cases of a reference type (like the Person type in my first model) the CLR will contrast the references with the items to check whether the references highlight a similar article. Two reference types may be equivalent if their reference focuses to a similar item on the oversaw stack.
