Multi-level inheritance involves at least 3 classes, a, b and c, such that a is derived from b, and b is derived from c. c is therefore the least-derived base class, b is an intermediate base class and a is the most-derived class.
struct employee { }; struct supervisor : employee { // single inheritance -- a supervisor inherits all the public and protected properties of an employee. }; struct manager : supervisor { // multilevel inheritance -- a manager inherits all the public and protected properties of a supervisor (and therefore an employee). };
Because it is one of the most important and widely used inheritance concepts in Java. In multi level inheritance a class directly inherits features from one class and indirectly inherits features form other classes that are in the inheritance hierarchy.
single level inheritance eg ( class B extends Class A) Multilevel inheritance eg( class C extends class B and class B extends class A) multiple inheritance Class C inherits Class A features as well as Class B featues.This type of inheritance is not allowed in JAVA.
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.
Java is related to C and C++ in the structure of programs composed with each language. All of them are object-oriented-programming languages (oop languages). Java is meant primarily for web apps C is meant primarily for programming servers C++ is meant primarily for large applications bbb
struct employee { }; struct supervisor : employee { // single inheritance -- a supervisor inherits all the public and protected properties of an employee. }; struct manager : supervisor { // multilevel inheritance -- a manager inherits all the public and protected properties of a supervisor (and therefore an employee). };

Yes.
single level inheritance eg ( class B extends Class A) Multilevel inheritance eg( class C extends class B and class B extends class A) multiple inheritance Class C inherits Class A features as well as Class B featues.This type of inheritance is not allowed in JAVA.
Grandfather-father-child relationship is an example for multi level inheritance..

Multiple inheritance, as the name 'multiple' suggests, is one where more than one(multiple) super class is inherited by one sub-class. It can be represented as:A B C\ | /DOn the other hand, in case of multilevel inheritance; the superclass is inherited by a sub-class which is in turn inherited by another class leading to the different level. It can be represented as:A|B|CHowever in asp, multiple inheritance is not supported.
there are several type of inheritance are exist like 1. single inheritance 2. double inheritance 3. multiple 4. multilevel 5. heirarchical inheritance
struct A {}; // base class struct B : A {} // derived class (single inheritance).
It cannot. Inheritance is a compile-time operation. Constructors are invoked at runtime at the point of instantiation.
struct base1 { // ... }; struct base2 { // ... }; struct derived1 : public base1 // single inheritance { // ... }; struct derived2 : public base1, public base2 // multiple inheritance { // ... };
