Runtime polymorphism feature in java is

A. method overriding

B. method overloading

C. constructor overloading

D. operator overloading

Correct Answer is :

A. method overriding

Explanation

Since in method overriding both the classes(base class and child class) have same method, compile doesn’t figure out which method to call at compile-time. In this case JVM(java virtual machine) decides which method to call at runtime that’s why it is known as runtime or dynamic polymorphism.
