You have the best explanations on KZfaq for Java. I'm here in the US, studying at a reputable university, but these guys just assign hardass problems, instead of teaching what the concepts are and how do they apply. Thank you very much :D

this is the first time I hear someone explaining why you would not want to access or change the values of instance variables directly. even my lecturer would just shrug and say "you just don't do it" or "this is not object oriented programming" (I learned to truly hate the latter phrase). thank you!

I want to ask who are the "users" that can access your private variables? Programmers? End user of the application? I still dont get the benefit of how the encapsulation really help, because the programmer can just open the source file and modify the source to access the private variables

Why do we need to access variables through methods(only!), what's the use of it? And why do we have to make a variable declaration as private? & What is a log file?

@naveent2785 4 жыл бұрын

I'm also thinking implementation of the object should be done through methods and so they need to be called to instantiate an object. But isn't a constructor can also be used to achieve this purpose. However, constructor creates a new object so everytime we want to change the member variables we can't create one!

@bluezgoldz 4 жыл бұрын

Might be too late to get to you but if I'm not mistaken, what he meant was you can track when your variable's value has changed because in order to change the variable within a getter/setter (POJO class) you'll need to access a method(). as you already know, you can do many funky stuff inside a method() including creation of a log file or a simple sysout statement to notify yourself that the variable has changed.

@anandn9869 2 жыл бұрын

This is not encapsulation.. many websites state encapsulation is for data security which is completely wrong.. Encapsulation just contains attributes and methods to operate on that properties in a single unit.. It's like capsule containing number of different ingredients. In your case once we create Student object, no matter what or where this object is transferred all its properties are encapsulated in it.. Data hiding is some thing which can be made by setting fields as private. Abstraction can be achieved to hide the implementation details to make sure the client does not need change if some thing that can be controlled inside a method itself.. Pleas correct it..

I know Nobody gonna reply it but even though... The burning question is instead of using get and set as encapsulation why don't we simply make variable private and use a method in a class to pass and call values... class Sample { private String name="Hawaii"; private int num; public int modern(int name) // Like This... { this.name=name; return name; }

@loknathmahapatra192 3 жыл бұрын

we declare the private variables so that couldn't be accessible from out of class. But we can implement or access them out of class using setter getter method. So if we have to implement it using setter getter method than any other person can implement it using setter getter method. . So how we are safe from manipulation??

The advantage is that now I have controlled access. It is like having librarian in college to provide books.Even now you will get books only difference is librarian can put restrictions not to issue more than 3 books at a time.same is case with making private and expose them through public methods

what happens if i put my variables public.

@traderslearningbackyard2191 3 жыл бұрын

Then anyone can come and change and no control

@traderslearningbackyard2191 3 жыл бұрын

Also say i have sid property in student object and if it is public anyone can access sid property from reference variable right like Student st =new Student(); st.sid=10; say there are hundreds of places like this and imagine u want to change from sid to studentId then u need to find thousand places and modify it it is going to break all existing code right ? Instead if u have exposed sid only through public method and making private property sid. If i want to change property name from sid to studentId i have to just change property and in public method from sid to StudentId now all my 1000 places which use my public method wont get affected at all as it doesnt know the implentation if i am using sid or studentId internally
