Inheritance Introduction, Why and when to use Inheritance?, Modes of Inheritance(public, protected, private), Types of Inheritance- (single, multiple, multilevel, hierarchical, hybrid, multipath)
This is the presentation file about inheritance in java. You can learn details about inheritance and method overriding in inheritance in java. I think it's can help your. Thank you.
Inheritance in java introduces the concept of reusability by implementing a mechanism in which one object acquires all the properties and behaviors of the parent object.
Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. It is an important part of OOPs (Object Oriented programming system).
The idea behind inheritance in Java is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you can reuse methods and fields of the parent class. Moreover, you can add new methods and fields in your current class also.
Inheritance represents the IS-A relationship which is also known as a parent-child relationship.
This whole C++ course focus on giving the insight of different kind of data structures that could be used while dealing with a variety of data that needs to be stored depending upon the circumstances.
The course also focus on how to reduce the complexity of a code by teaching us the variety of approaches that could be employed for a solving the same problem.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
2. Introduction
• There are three pillars fundamental to the edifice that is
object oriented programming.
• Inheritance
• Encapsulation
• Polymorphism
• It is these three things that turn object orientation from a
gimmick into an extremely powerful programming tool.
3. Inheritance
• In this lecture we are going to talk about inheritance and
how it can be applied to C++ programs.
• There are several important differences here between Java and
C++.
• Java and C# are single inheritance languages.
• C++ supports multiple inheritance.
• This is much more powerful, but also very difficult to do well.
4. Inheritance
• The concept of inheritance is borrowed from the natural
world.
• You get traits from your parents and you pass them on to your
offspring.
• In C++, any class can be the parent of any other object.
• The child class gains all of the methods and attributes of the
parent.
• This can be modified, more on that later.
6. Inheritance
• Inheritance is a powerful concept for several reasons.
• Ensures consistency of code across multiple different objects.
• Allows for code to be collated in one location with the concomitant
impact on maintainability.
• Changes in the code rattle through all objects making use of it.
• Supports for code re-use.
• Theoretically…
7. Inheritance
• In C++, the most general case of a code system belongs
at the top of the inheritance hierarchy.
• It is successively specialised into new and more precise
implementations.
• Children specialise their parents
• Parents generalise their children.
• Functionality and attributes belong to the most general
class in which they are cohesive.
8. Inheritance
• In Java, the concept is simple.
• You create an inheritance relationship by having one class extend
another.
• The newly extended class gains all of the attributes and
methods of the parent.
• It can be used, wholesale, in place of the parent if needed.
• We can also add and specialise attributes and
behaviours.
• This is the important feature of inheritance.
9. Inheritance in Java
public class BankAccount {
private int balance;
public void setBalance (int b) {
balance=b;
}
public int getBalance() {
return balance;
}
}
public class MainClass {
public static void main (String args[]) {
BankAccount myAccount;
myAccount = new BankAccount();
myAccount.setBalance (100);
System.out.println ("Balance is: " + myAccount.getBalance());
}
}
10. Inheritance in Java
public class ExtendedBankAccount extends BankAccount{
private int overdraft;
public boolean adjustBalance (int val) {
if (getBalance() - val < 0 - overdraft) {
return false;
}
setBalance (getBalance() - val);
return true;
}
}
11. Constructors And Inheritance
• When a specialised class is instantiated, it calls the
constructor on the specialised class.
• If it doesn’t find a valid one it will error, even if one exists in the
parent.
• Constructors can propagate invocations up the object
hierarchy through the use of the super keyword.
• super always refers to the parent object in Java.
• Easy to do, because each child has only one parent.
• In a constructor, must always be the first method call.
• Everywhere else, it can be anywhere.
12. Constructors and Inheritance
public class BankAccount {
private int balance;
public BankAccount() {
balance = 0;
}
public BankAccount (int
startBalance) {
setBalance (startBalance);
}
public void setBalance (int b) {
balance=b;
}
public int getBalance() {
return balance;
}
}
public class ExtendedBankAccount extends
BankAccount{
private int overdraft;
public ExtendedBankAccount (int startBalance) {
super (startBalance);
}
public ExtendedBankAccount (int startBalance, int
startOverdraft) {
super (startBalance);
overdraft = startOverdraft;
}
public boolean adjustBalance (int val) {
if (getBalance() - val < 0 - overdraft) {
return false;
}
setBalance (getBalance() - val);
return true;
}
}
13. Inheritance in C++
• At its basic level, very similar to Java.
• A single colon is used in place of the extends keyword.
• We also include public before the class name.
• We’ll talk about why later.
• We have no access to variables and methods defined as
private.
• More on that in the next lecture.
14. Inheritance in C++
class ExtendedCar : public Car {
private:
float mpg;
public:
ExtendedCar(float mpg = 50.0);
void set_mpg (float f);
float query_mpg();
};
ExtendedCar::ExtendedCar (float mpg) :
mpg (mpg) {
}
float ExtendedCar::query_mpg() {
return mpg;
}
void ExtendedCar::set_mpg (float f) {
mpg = f;
}
15. Constructors in C++
• Constructors in specialised C++ classes work in a slightly
different way to in Java.
• Constructors cannot set the value in parent classes.
• This syntactically forbidden in C++.
• By default, the matching constructor in the derived class (child class)
will be called.
• Then the default construtor in the parent will be called.
• From our earlier example, the code will call the matching
constructor in ExtendedCar, and then the parameterless
constructor in Car.
16. Constructors in C++
• If we want to change that behaviour, we must indicate so
to the constructor.
• In our implementation for the constructor, we indicate which of the
constructors in the parent class are to be executed.
• We must handle the provision of the values ourselves.
17. Constructors in C++
class ExtendedCar : public Car {
private:
float mpg;
public:
ExtendedCar(
float cost = 100.0,
string colour = "black",
int max_size = 10, float mpg = 50.0);
void set_mpg (float f);
float query_mpg();
};
ExtendedCar::ExtendedCar (float cost, string colour, int max_size, float mpg)
: Car(cost, colour, max_size),
mpg (mpg) {
}
18. Multiple Inheritance
• The biggest distinction between C++ and Java inheritance
models is that C++ permits multiple inheritance.
• Java and C# do not provide this.
• It must be used extremely carefully.
• If you are unsure what you are doing, it is tremendously easy to make
a huge mess of a program.
• It is in fact something best avoided.
• Usually.
19. Multiple Inheritance
• We will touch on syntax, rather than discuss it.
• Don’t want to introduce something I don’t want you using!
• However, important you understand what is happening when you
see it.
• Inheritance defined in the same way as with a single
class.
• Separate classes to be inherited with a comma
• Class SuperVehicle: public Car, public Plane
20. Multiple Inheritance
• What are the problems with multiple inheritance?
• Hugely increased program complexity
• Problems with ambigious function calls.
• The Diamond Problem
• Hardly ever really needed.
• For simple applications, interfaces suffice.
• For more complicated situations, design patterns exist to resolve all the
requirements.
• Some languages permit multiple inheritance but resolve some
of the technical issues.
• C++ isn’t one of them.
21. Summary
• Inheritance is an extremely powerful tool.
• Provides opportunities for code re-use and maintainability.
• Inheritance in C++ is very similar to inheritance in Java.
• With some exceptions.
• C++ permits multiple inheritance.
• Not something you often need.
