How Can I Determine an Object's Class in Object-Oriented Programming?

Determining an Object's Class

In object-oriented programming, it can be useful to determine the class of an object, especially when working with inheritance. Consider a scenario where you have class B and class C that extend class A. If you have an object of type B or C, you may need to determine which type it is an instance of.

To resolve this, you can utilize the instanceof operator. This operator checks whether an object is an instance of a specified class or its subclasses. In your case, to determine if the object is an instance of class C, you would use the following syntax:

if (obj instanceof C) {
//your code
}
Copy after login

If the obj is an instance of class C, the code block will be executed. Conversely, if the obj is an instance of class B but not class C, the code block will not be executed.
