How Can I Determine the Specific Class of an Object in Java?

Determining an Object's Class

Suppose you have an object of type B or C, where class B and class C both extend class A. How can you ascertain which type the object belongs to?

Solution:

Java's instanceof operator can be employed to determine an object's class. Here's an example:

if (obj instanceof C) {
    // Code to be executed if the object is an instance of class C
}

In this example, obj represents the object whose class we want to determine. If obj is an instance of class C or a subclass of C, the condition in the if statement will evaluate to true.

This approach allows you to check the specific class or a subclass of an object. You can perform similar checks for other classes, such as:

if (obj instanceof B) {
    // Code to be executed if the object is an instance of class B
}

By using the instanceof operator, you can dynamically determine an object's class and execute code accordingly.
