Question

Which of the following inheritance is/are not supported by Java?

Multi-level Inheritance

Hierarchical Inheritance

Single Inheritance

Multiple Inheritance

Answer: Multiple inheritance​

Answer 1

Explanation:

Explanation: Since java doesn't support multiple inheritance, it is not possible for a class to inherit more than 1 class in java. This is the same case in C# also. 15. If multi-level inheritance is used, First class B inherits class A, then C inherits B and so on.

Answer 2

Answer:

Multiple Inheritance is not supported by Java.

Explanation:

• Java doesn't support multiple inheritance using classes.
• Multiple Inheritance is a feature of an object-oriented concept, where a class can inherit properties of more than one parent class.
• The problem occurs when there exist methods with the same signature in both the superclasses and subclass.
• Multilevel Inheritance occurs when a class extends a class that extends another class. 
• The type of inheritance in which more than one derived class inherits the properties of the same base class is called hierarchical inheritance.
• There are multiple child classes and a single parent class.
• Single Inheritance allows a derived class to inherit the properties and behavior of a base class, thus enabling code reusability as well as adding new features to the existing code.
