Introduction
Software applications are developed with a lot of methods using different programming languages and frameworks. In the process of developing a software application, one needs to write a lot of codes with their proper paradigms and structure. Following the proper logic and algorithms provide the application a better running environment and easiness, this will reduce the complexity of that developed application as well as allow the developer to maintenance and updating the application in the future.
Besides all these things it is very important to check or test the developed application. One can debug the application if there is any chance of getting the bugs or one can test the application for its functionality and the working process. The estimation of the testing result can be evaluated on the basis of the output of that program and can also be evaluated on the basis of their time complexity and other parameters. One of the other methods to check the performance and quality of the code is by “Refactoring”. In the Refactoring process, the developer has to change the codes in such a manner that it will not affect the final output of the program (Paligot,2015). There are various methods of Refactoring which are discussed in this assignment briefly using the codes provided for this assignment.
Here, in this assignment, it is clearly discussed about the refactoring and their process which is performed on the provided code. In this assignment, the learner has used his GitHub repository to import and push the code and used Eclipse java IDE for refactoring and other updates in codes.
Introduction to GitHub repository
GitHub provides online platforms for developers to write and cook their codes. Here coders can write as well as edit their codes and can also take references from someone other’s code. GitHub also provides a feature to create a repository of the code. F4 this assignment the learner is sung the GitHub repository to extract the provided code and to repost the code after refactoring and performing other operations from his local IDE. GitHub repository will provide the facility for the user to use and share the codes from copying the SSH or HTTP link or by cloning it to the local file.
Introduction to eclipse repository
Eclipse performs the same function as GitHub does but it works offline for the local system. For this assignment the user is using the Eclipse IDE for creating the repository and to clone it and pushing it to the GitHub repository. From the GitHub repository, the user has to clone the code and have to use the local IDE for operating on it. In the eclipse IDE, they also provide the facility to create and edit the local as well as an imported repository.
Introduction of Refactoring
In the process of software development, there are a lot of processes involved which should be performed to make a well-functioning and efficient software application. In meanwhile refactoring is one of them, usually, the developers don’t prefer to check the developed application through the refactoring process but instead of this, they prefer for the testing.
The process of refactoring mainly includes the distraction of codes which means in the refactoring process the developer has to make changes in the code in such a way that it will not affect the final output data. The codes should be changed in such a manner that the final result should be untouched and if in any case the final result gets changed the refactoring process will fail (Verdecchia,2018).
Refactoring methods
There are various types of refactoring, in the process of refactoring developers can change it with class, superclass, or its objects, in each of the cases the final result should remain the same. There are some common refactoring methods which are mentioned below. Here in this assignment, the learner will perform the refactoring process one by one with each and every method (Kim,2107).
Extract method
Here in the refactoring process during the lab work, the learner tried to change the method of the java class “Animal” from string but got an error message (Appendix 2). This shows that the refactoring process for the class Animal is failed, if one tries to refactor the animal class it will affect the output of the whole file.
Extract class
In the section, the learner performed the re-factorization with the class of the java file. As the learner is operating on the java code it is impossible to make changes in the main class of the java file so refactoring with extracting the java class will automatically get failed in every case.
Extract superclass
In the case of the superclass, one can extract the superclass as it has the data related to that specific class where the superclass is implemented. As seen in the previous method the learner was unable to change the main class of the java file but here one can do the refactoring with the superclass of that java file. The result and the code are attached in Appendix 1.
Extract interface
Extracting the interface means changing the interface of that class. Here the learner tried changing the interface of the Animal.java file from a string to the character but it showed an error message. The reason behind this is if one has to change the interface of any class then he has to change with the suitable interface value which can be executed by the Javac unless it will always lead to an error. The error message for this is also attached in Appendix 2.
Rename
This one is a simple one and it does not make any changes after the refactoring.
Move
In Eclipse ide the move only redirects to the movement of the selected class between the packages. It will also pass the refactoring process successfully.
Pull up and Push down
Pull up and push down are the process which is used in the refactoring process to pull or push the code assigning with their subclass. The most important point of these two methods is that this can be done only in those files which have the subclass. The java file without having a subclass will not allow performing this operation. In this assignment, we performed these two applications on Animal class and due to the unavailability of the subclass, the action gets aborted.
Extract supertype where possible
This action will replace the types present in the class files only where it is possible.
File comparison
For the veterinarian file, the learner changed the class from private to public leaving all the source code as it is. in this refactoring process also the output remained the same. This shows for this specific java class file changing the attribute will not affect the behavior of the source code and from this result, one can say that the refactoring process is successfully achieved.

Best Assignment Help Melbourne
I have so far ordered four hospitality and tourism assignments with this website. For two of the assignment they were done very nicely with all proper writing, referencing and citations and I got a good grade distinction for both of them. I am really happy with the outcome of this Australia assignment help service. My third assignment was actually a dissertation proposal and literature review writing assignment for customer relationship management hospitality course and that one needed a little bit modification as suggested by my professor. I immediately reported the feedback to Cheapassignmenthelp.co.uk and these guys provided me 2 times free rework and in the end that assignment also I got a distinction. So all is well and good for me. I normally pay a decent charge to get a decent quality assignment but I am happy with the overall quality of assignment writing, literature review is good and standard journals and references are used by the writers. Overall customer care is also very helpful and makes sure that I am given a good attention to understand my order details and any rework. Its a fast service and I have received most of my work before 2 days deadline also.
I would give you ration 10
This online assignment site has not only impressed me but my parents as well. After my school, my mother had to spare some extra time to help me with my homework’s and projects and because of this she frequently have to take half time from her office. But from the time I interact with the members of this site, all the problems are completely resolved. I can stay at home and learn under the guidance of expert and my mother no more need to take leave from her work. My grades also showed good improvements. So this site have erased our problems and helped me learn in the homely environment.

It has been a long time when I was working on the project given in the college, but still, I failed to complete it in the desired manner. The date of submission was near and I was worried about the work. Then I got to know about this site from different friends. My work was completed before the allotted time and that too in very impressive and effective way. Cheap assignments were appreciated by teachers and all my fellow classmates. It was a great feeling….

1 INTRODUCTION
Information is the most valuable resource that an organisation possesses. The effective gathering, protection, analysis, processing and dissemination of information is vital to the success of any organisation. As globalization and the 24-hour economy develop and increase, organisations must ensure that their Information Systems are reliable, efficient and able to cope with rapid change.
Organisations whose Information Systems previously dealt purely with data processing have now introduced those supporting strategic management and decision support. Managers at all levels need appropriate and timely information to plan successfully in the short, medium and long term, and that information can have many sources and destinations. As organisations diversify and decentralise, information also needs to be available to many non-managerial staff in a variety of locations. The logical conclusion is that an organisation is now completely dependent on the effectiveness of its Information Systems in order to survive and thrive in the 21st century business environment.
Learners will begin this unit by analysing the information needs of an organisation at different levels and within different functional areas. It is important that computing professionals are able to understand how an organisation works and how it uses information, in order to be able to design, implement, maintain, and manage systems to support its operation.
On completion of this unit, learners will understand the importance of effective Information Systems to an organisation. They will be aware of the variety of options available for information processing and know that these will inevitably change over time. They will also use an information system to produce management information.
