Which of the following cannot be Type parameterized?
A. Overloaded Methods
B. Generic methods
C. Class methods
D. Overriding methods
Answer: Option C
Solution (By Examveda Team)
Generics in Java are tied to the type of objects, meaning they work at the instance level.Static methods belong to the class itself and are shared across all instances.
Since generics are resolved at the object level, type parameters cannot be directly used within static methods.
Why the other options are incorrect:
Option A: Overloaded Methods
Overloaded methods can have different generic type parameters.
The compiler can differentiate them based on their method signatures, making generic type parameters valid for overloaded methods.
Option B: Generic methods
Generic methods explicitly use type parameters, and this is a common and valid usage of generics in Java.
Option D: Overriding methods
Methods with generic type parameters can be overridden.
The overridden method must respect the same type parameter or use a wildcard (?).

What is the main purpose of generics in Java?
A. To enable type-safe collections and eliminate type casting
B. To increase program execution speed
C. To simplify the syntax of Java code
D. To improve memory management
In a generic class, what does the wildcard `` represent?
A. A wildcard type
B. A specific class
C. An unknown type
D. An exception type
What is the benefit of using generics with collections in Java?
A. It allows collections to store any type of elements
B. It ensures type safety by allowing only specific types of elements
C. It reduces the size of collections
D. None of These
The answer should be overriding methods beacuse the overriding method must have the exact same signature (name, parameters, and return type) as the method in the superclass. So, it cannot introduce new type parameters.
