Inheritance is one of the fundamental properties of java, allowing subclasses to inherit all of the public methods and data members of their respective superclasses. For instance, assume there are three classes named "Bug", "Arachnid", and "Black Widow". Arachnid extends (inherits) Bug, and BlackWidow extends Arachnid. Therefore, BlackWidow inherits all of the properties of Arachnid (eight legs, segmented body, etc) and all of the properties of Bug (small, creepy, exoskeleton, etc). Arachnid only inherits Bug.

What is default object in java?
I don't think there is such a thing as a "default object". The default class, for inheritance purposes, is called "Object".
What does java not support?
Java does not support multiple inheritance.......
Give the structure of multiple inheritance?
Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.
How ploymorphism and inheritance is different from that in Java and c plus plus?
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.
Why you neet interface in java?
When you need the benefits of multiple inheritance while avoiding the DDD (Deadly Diamond of Death). Java doesn't allow multiple inheritance anyway.

What is ambiguity in multiple inheritance?
Java does not support multiple inheritance
What kind of inheritance is not allowed in java?
Java does not allow the multiple inheritance of concrete classes, though it does allow a "hybrid" inheritance of one concrete class and multiple interfaces.
What is problem in multiple inheritance?
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.

What is public inheritance in java?
Inheritance is a Java feature by which we can reuse code and programming logic from one class in another class. We implement Inheritance using the extends keyword.Ex: public class Ferrari extends Car {…}Here the Ferrari Class will extend features from the Car Class.This is Inheritance. The different types of Inheritance are:Single InheritanceMulti-Level InheritanceMultiple Inheritance (Java supports only Partial Multiple Inheritance) andHybrid Inheritance

Need of interface in java?
Interfaces are used in Java to accomplish most of the goals of Multiple Inheritance. For several reasons, Java only supports Single Inheritance for classes - i.e. a class can have only a single parent. The use of Interfaces is how Java attempts to implement most of the positives of the concept of Multiple Inheritance while avoiding its pitfalls.
Why you neet interface in java?
When you need the benefits of multiple inheritance while avoiding the DDD (Deadly Diamond of Death). Java doesn't allow multiple inheritance anyway.
What types of inheritance in Java programming?
Java uses a hybrid system of inheritance. The designers chose a compromise between strict single inheritance and full multiple inheritance.See the related questions section below for more information.
How do you implimenting multilevel inheritance in java?
In java we can implement more than one interfaces for a single class but we can't extend a class to more than one super class so ,java indirectly supports multiple inheritance.
