Java GETTER and SETTER tutorial to get and set Field Variables. Object Oriented Java Tutorial #9.2

[@blockbusterlatefees7713]

Perfectly explained. You actually show what happens to "pug" and where it gets replaced. Excellent! Thanks!

[@minoanlight4545]

No one, I repeat NO ONE was able to explain this to me this well. Thank you so much, I do not know if I am dumb or what, but I struggled so much with this. I understand other Java concepts pretty well, but this one was a nightmare to me. I thought about giving up and setting the variables the other way forever, but I knew there would be situations where I would have to make variables hidden like this. Thank you, thank you so much.

Getters and Setters Getters and Setters are used to effectively protect your data, particularly when creating classes. For each instance variable, a getter method returns its value while a setter method sets or updates its value. getters and setters are also known as accessors and mutators, respectively.

I am a beginner and you have not given the basic explanation of "WHY" are we not supposed to access the variables DIRECTLY. That would certainly help in boosting fundamentals of a beginner like me. But overall good one. Thank you.

[@smartherd]

Well the are few things which Google can tell you. Rest will be taken care by my videos. :P

Awesome, thank you!

Can't we use set and get methods in different functions separately?

[@nikhithanikki8413]

I have created a pojo class with setters and getters. In class A I have set the values and in class B I wanted to get the values . Kindly help me how to create object and get the values

[@divyalakshmithota3444]

Can you please explain how the getter and setter work in case when we enter values dynamically using input fields in run time...I mean how it will set the values? Will it take values directly from fields or from database?

[@mervinlee450]

Must we always use setter and getters? Can't we just retrieve the information directly from the database? I at times always get a null pointer exception with setter and getter...

[@mathiasfantoni2458]

I still don't get why we would use getter and setter way instead of just setting the variables public? What is the computational benefit of mutating them with methods rather than directly?

[@KD-xi9wu]

Sir what's the advantage of setter and getter over directly accessing variables using dot operator ( . )???????

[@smartherd]

Abstraction and encapsulation

Awsum Work .. actully i am learning through another persons video tutorial , but when i got stuck in any thing , always found solution in your tutorials , so simple yet so clearing .. Awsum work love from Pakistan .

[@kingsley15]

Your variables should be *private* .

[@MK-qz7sg]

why?

[@kamalanb6930]

@@MK-qz7sg getters and setters are mostly used to provide data values to private variable. To access data from public variable and provide it to a private variable we use getter and to set a value we use setter.

How do I access a protected getter setter in another package in Java?

[@boominathanarumugam5589]

you explained very well no doubt but you have additionally include what is the use of this method and why we are using these type of methods in java because we have learned these types of concepts but where it will be used in right way we don't know so i hope you will explained in future videos

[@muslimquotesofficial]

U said it ...he should clearly explain the reasons

[@xxxx-kv9ei]

ok these are used ideally in game development but can be used for other purposes to it. most importantly you guys need to go ask yourselves a question and solve it. Thats how you learn programming, it is not learned by just listening. for example if I were to learn SQL, i would need to ask myself, Use adventureWorks2014 and Get me all the sales which has more than 5 products, get customer details, the dates should be UK format. and make a full name. when trying to answer that question, in the process I will learn SQL. so you guys need to go out and make scenarios in your mind and try to solve them.

[@ujwalareddy-n7b]

Awesome, Explanantion.🙌🏻

[@juandavidgomezrestrepo6110]

Thanks my friend really well explained

[@chandrasekhar6362]

can we set the values in one request and can we retrieve in other request?

[@hardikseth9640]

fantastic explanation and simple and to the point

[@emekamgbemere1801]

I can't thank you enough. You understand this and it's obvious in your explanation. Thanks.

[@amitkadam2354]

is getBreed() contains the value of breed

[@tejaslokhande6452]

Sir But anyone can access our data if he reads our code even if we have Encapsulated. Then how it works please help?

[@rushabhoswal8280]

getter and setter are used to access private field using public method right? Then can we access private methods using the same strategy?

[@rushabhoswal8280]

Great videos!I am learning java through your everyday modules 😃! Can getter and setter be static method?can it be another than public?

[@smartherd]

The purpose of Getter and Setter is to be public or sometimes protected. But not private. and you can access private methods by calling a public method from outside the class.

[@rushabhoswal8280]

Why to access private variables using public method?whereas we can access public field easily?

[@smartherd]

Thankyou, You can provide me feedback to make my videos more clear and better. or if you find any better video on youtube then let me know.

[@smartherd]

thats for this video was all about. Its always better to access field variables using getter and setter instead of doing it directly. The more in depth reason you will get to know while doing projects.

[@mithunchandrasaha403]

Nice Explanation.Sir

[@simm5622]

Nicely explained 👍

[@masbro1901]

for what reason we should not access the variable directly ?

[@lokeshdohare4872]

mas bro it's a instance variable, u cannot access instance varaibles directly inside a method.. U either make object of that class and access it using reference variable or use getter and setter method as explained in video.

[@theoriginyt4869]

Coming from C++ and C#, I see no point in using these at all. Just use the field directly for even a better performance. Or use C# to specify if a variable should be only set privatly or be accessed by public...

[@bushratarif6028]

Wow, amazingly explain!

[@xxxx-kv9ei]

For those asking "tell us how to use it". ok these are used ideally in game development but can be used for other purposes to o. most importantly you guys need to go ask yourselves a question and solve it.

[@srilekham8288]

its not alternative method for using getter and setter methods.They are used when the variables are private

[@smartherd]

Yes. But here as mentioned at 2:29 that here pug is a string variable.

[@IdlanRafiqi]

Then, what is the correct code? dog1.setBreed("pug"); or dog1.setBreed(pug); ?

This is why i think java is so dumb. The getter and setter are doing exactly the same thing as the first code.

[@rockmusicvideoreviewer896]

This is really a very horrible answer (your reply to some in the comments). If you come straight out and tell us in your video that one way is not a good way and to use a 2nd way instead, you better tell us why. Telling us in a comment to google it is wrong. Humble yourself and explain it in the comment and don't be afraid to admit when you are wrong. Otherwise you come off as someone that only cares about his own ego.
