How is inheritance useful to polymorphism in Java?

Inheritance is a powerful feature in Java. Java Inheritance lets one class acquire the properties and attributes of another class. Polymorphism in Java allows us to use these inherited properties to perform different tasks. Thus, allowing us to achieve the same action in many different ways.

What comes under polymorphism in Java?

What is multiple inheritance Mcq?

Explanation: The multiple inheritance is used when a class is being derived using two base classes or more. This way a single class can have features of more than one classes inherited into a single unit. This lets us combine two class members into a single class. 2.

Which keyword is used to inherit a class in Java Mcq?

Q) Which polymorphism feature is related to parent and child class relationship in java. Explanation: Method overriding feature is always used in parent child relationship in inheritance in java.

Which function best describes the concept of polymorphism in programming languages Mcq?

Runtime Polymorphism: It is meet by the function overriding. This polymorphism is also known as late or dynamic binding. Compile-time Polymorphism: It is meet by the operator and function overloading. This polymorphism is also known as early or static binding.

Which of the following are an example of polymorphism?

A real-life example of polymorphism, a person at the same time can have different characteristics. Like a man at the same time is a father, a husband, an employee. So the same person posses different behavior in different situations. This is called polymorphism.
