Java MCQ: Which method is used to obtain the superclass of a class using Java Reflection?

Answer:

Explanation:

The getSuperclass() method in Java is used to obtain the superclass of a class using reflection. This method is part of the Class class and returns a Class object representing the superclass of the class represented by the current Class object. If the class has no superclass (e.g., it is Object), then the method returns null.

Here’s an example of how to use getSuperclass():

public class GetSuperclassExample {
    public static void main(String[] args) {
        Class<?> superclass = Integer.class.getSuperclass();
        System.out.println("Superclass of Integer: " + superclass.getName());
    }
}

In this example, the getSuperclass() method is used to obtain the superclass of the Integer class. The name of the superclass is then printed to the console. This method is particularly useful when writing reflection-based code that needs to navigate the inheritance hierarchy of classes dynamically.

Understanding and utilizing the getSuperclass() method is important for developers who need to work with class hierarchies in a flexible and dynamic manner, such as in ORM frameworks, serialization libraries, or custom class loaders.
