Class hierarchy is a fundamental concept of object oriented programs explain what this term means with reference to inheritance abstraction and instantiation?
Class hierarchy is a term used in Java. It is used for identifying the inheritance hierarchy or the parent class relationships Ex: Public class B extends C { } Public class A extends B { } Here if we take the class hierarchy for class 'A' it would be A
What is the difference between the direct and indirect base class?
Direct base classes are those that are specified in a derived class' inheritance declaration. Indirect base classes are those that are inherited via the direct base classes. class A{}; class B : public A{}; class C : public B{}; With respect to C, B is direct while A is indirect. With respect to B, A is direct.
Simple hierarchical inheritance program in java?
Multilevel inheritance is a java feature where the properties of a class are inherited by a class which extends one or more classes which extend its features...Example:public class A {public String getName(){return "Rocky";}}public class B extends A {public int getAge() {return 24;}}public class C extends B {public String getAddress(){return "North Carolina, USA";}}public class D extends C {public void print {System.out.println(getName());System.out.println(getAge());System.out.println(getAddress());}}This method would print the following in the console:Rocky24North Carolina, USAHere in class D you are calling methods that are available inside classes A, B & C. Though D extends only class C, it would in turn inherit the properties of the classes extended by C and its parents.This is multi level inheritance.
What is the valid class declaration header for the derived class d with base classes b1 and b2 A class d public b1 public b2 B class d class b1 class b2 C class d public b1 b2 D class d b1 b2?
What is the valid class declaration header for the derived class d with base classes b1 and b2?A. class d : public b1, public b2 {/*...*/};B. class d : class b1, class b2 {/*...*/};C. class d : public b1, b2 {/*...*/};D. class d : b1, b2 {/*...*/};The answer is A, C and D.B is not valid because "class" is not a valid access specifier.All the others are valid because private access is the default when the access specifier is omitted. Note that if class D were declared using the struct prefix, inheritance would default to public access rather than private.
Write program java explain use abstract class multilevel inheritance?
Multilevel inheritance is a java feature where the properties of a class are inherited by a class which extends one or more classes which extend its features...Example:public class A {public String getName(){return "Vijay";}}public class B extends A {public int getAge() {return 24;}}public class C extends B {public String getAddress(){return "Utter Pradesh,INDIA";}}public class D extends C {public void print {System.out.println(getName());System.out.println(getAge());System.out.println(getAddress());}}This method would print the following in the console:Vijay24Pradesh,INDIAHere in class D you are calling methods that are available inside classes A, B & C. Though D extends only class C, it would in turn inherit the properties of the classes extended by C and its parents.This is multi level inheritance.
What is cost of class a and class b private address?
Nothing (0). Anyone can use a private class A or B address in their network because the packets with those addresses are not routed.
Which class does the IP address 199.199.10.0 belong to?

A node with an IP address of 168.34.88.29 belongs to a Class?
Class B Address
What is default subnet mask for a class b address?
255.255.0.0255.255.0.0 is the default for a class B address
What IP address is used by Class B private networks?
Class B private networks use the IP address range from 172.16.0.0 to 172.31.255.255. This range is reserved for private use, meaning these addresses are not routable on the public internet. Devices within a Class B private network can communicate with each other without needing public IP addresses, facilitating local networking.
If you have a computer with the IPv4 address 163.208.199.8. What class is this address?
The IPv4 address 163.208.199.8 belongs to the class B address range.Class A - 1.0.0.0 - 126.0.0.0Class B - 128.0.0.0 - 191.255.0.0Class C - 192.0.0.0 - 233.255.255.0

What class is 172.16.128.17?
The IP address 172.16.128.17 belongs to Class B. Class B addresses range from 128.0.0.0 to 191.255.255.255, and they are typically used for medium to large networks. The first two octets (172.16) indicate that it is part of the private IP address space, which is not routable on the public internet.
Write a program to demonstrate multilevel inheritence in java?
Ex: public class A { ... } public class B extends A { ... } public class C extends B { ... } Here class C extends B which in turn extends A so class C indirectly extends class A.
