What is single inheritance in Java?

• Single inheritance means a class cannot inherit any properties from a superclass.

• Single inheritance allows a class to inherit from multiple superclasses.

• Single inheritance is a feature that allows a class to implement multiple interfaces.

• Single inheritance allows a class to inherit from one superclass only.

Can a class in Java inherit from multiple classes?

• Yes, a class in Java can inherit from multiple classes.

• No, a class in Java cannot inherit from multiple classes.

• A class in Java can implement multiple classes.

• Java supports multiple inheritance through interfaces.

What is the concept of multilevel inheritance in object-oriented programming?

• A class 'Vehicle' that does not inherit from any class, which does not demonstrate multilevel inheritance.

• For instance, consider a class 'Shape' as the base class. A derived class 'Polygon' inherits from 'Shape', and another class 'Triangle' inherits from 'Polygon'. In this case, 'Triangle' can access properties of both 'Polygon' and 'Shape'.

• A derived class 'Square' inherits from 'Triangle', which is not a valid example of multilevel inheritance.

• A class 'Shape' inherits from 'Triangle', which is incorrect.

What is hierarchical inheritance in Java?

• Hierarchical inheritance allows a class to inherit from multiple classes in a tree-like structure.

• Hierarchical inheritance is a method for creating interfaces in Java.

• Hierarchical inheritance is when a class cannot inherit from any other class.

• Hierarchical inheritance allows a class to inherit from a single class only.

Define hybrid inheritance and its significance.

• Hybrid inheritance is solely based on interface implementation.

• Hybrid inheritance only involves single inheritance.

• Hybrid inheritance is a method to avoid multiple inheritance.

• Hybrid inheritance is a combination of multiple and single inheritance, allowing for flexible class hierarchies.

What are the advantages and disadvantages of single inheritance in object-oriented programming?

• Single inheritance promotes a clear and straightforward class hierarchy.

• It can lead to issues with code duplication and reduced flexibility.

• Single inheritance allows for easier understanding of class relationships.

• It enables the use of multiple inheritance features.

How does Java handle multiple inheritance?

• Java handles multiple inheritance through interfaces, allowing a class to implement multiple interfaces but not inherit from multiple classes.

• Java allows multiple inheritance from multiple classes directly.

• Java uses abstract classes to achieve multiple inheritance.

• Java does not support inheritance at all.

Which of the following is an example of hierarchical inheritance in Java?

• class A extends B { } class B extends C { }

• class A { } class B extends A { } class C extends B { }

• class A { } class B { } class C extends A { }

• class A extends C { } class B extends A { }

What is the main advantage of hierarchical inheritance?

• Limited flexibility in design.

• Increased complexity in code management.

• Code reusability and organized structure.

• Higher memory consumption during execution.

Aarush is working on a project that involves creating a complex web application. He needs to implement various functionalities that require features from multiple base classes. Describe a scenario where hybrid inheritance would be useful for his project.

• Hybrid inheritance is useful in creating complex UI components that require functionalities from multiple base classes.

• Hybrid inheritance is useful for creating simple data structures with a single base class.

• Hybrid inheritance is primarily used for database management systems.

• Hybrid inheritance is effective in developing mobile applications with limited functionality.
