Java Tutorial 19 - Accessor and Mutator Methods (Setters and Getters)

[@soramakizushi]

You explained in less than 10 minutes what my teacher couldn't in an entire period. Thank you so much!

I'm glad to hear that you found this video helpful! Thank you for watching and for taking the time to comment - it's greatly appreciated! Best wishes with your studies!

Teachers are chosen for their wealth of knowledge on subjects, not their teaching ability. They are not one and the same.

[@aaryadeshpande1621]

You literally explained the concepts to the point where I could teach someone else. Literally, I never understood anything about this before. This video has really taught me that when it comes to programming, actually coding yourself, questioning, then teaching is the best explanatory process (teacher). I often don't get a word my teacher or my textbook says when explaining such concepts in Java because they have no meaning until you have the picture (engaging yourself). Videos like these are lifesavers! (This was like Khan Academy, but Computer Science) Thank you!! Keep up the videos!!

Incredibly well demonstrated! I like how you get straight to the point right off the bat. This is like visual gold. Bar none the best lesson I've seen on the topic. Bravo!!

watching this right the night before a unit test on strings and classes. youre a life saver! :)

To be honest, I am new to Java. your tutorials are so helpful and easy to follow. I am currently follow series of your tutorials and they are amazing.

Thank you for watching and for taking the time to share your feedback! I’m glad you find these tutorials helpful! Please let me know if there are any specific topics you’d like to see covered in future videos or if you have any questions! I’d be happy to try and help out where I can!

[@giahmed82]

@@TechnicalCafe Many thanks for your reply. I need some help with converting int array to double array. I have watched your tutorial 6 for Arrays but have not come across something which converts int array to double or int array to ArrayList. Can you please cover this topic?

[@christineslotkoff8941]

You should teach my programming class! I can't believe I actually understand my assignment now. thank you!!

[@TechnicalCafe]

Hi, Christine! Thank you for watching and for taking the time to leave such a kind compliment! I'm glad that you found this tutorial useful and wish you the best in your programming class! What class are you taking?

[@samsonwong8242]

Very clear and excellent background why setters/getters are needed. Well done

[@MeshTheSnake]

Your the man with the master plan, this really helped clearly up this concept for me. Thanks you!

[@TechnicalCafe]

+NatMesh Thanks for watching and for taking the time to comment. Glad you found this helpful! Please let me know if there's anything else you'd like to see a video about.

[@MeshTheSnake]

no problem! Could you actually make a video on multidimensional arrays and partially fully arrays(adding new elements to an array and deleting elements)? Thanks!

[@TechnicalCafe]

Thank you for the suggestions! I just posted a video about ArrayLists in Java, if you're interested in checking that out. It's not exactly what you were asking for, but somewhat related.

[@TheNivKo]

Just want to say thank you so much for all the videos you really helped me a lot!!! :)

[@saidmshah8574]

Thanks, it helped me a lot and got me out of a big confusion.

[@krillonusa]

ayy thanks for breaking it down. I understood the get, but didn't really understood the mutator. I didn't know what the output was supposed to be. Now I get the concept of my assignment.

[@TechnicalCafe]

Glad to hear that you found this helpful! Best wishes on your assignment! Are you a computer science major? Please don't hesitate to let me know if you have any questions, comments, or suggestions!

[@krillonusa]

Yeah I am a CS major. I have to create a program that displays a Cube's dimensions using sets/gets

[@TechnicalCafe]

Nice! Hope the project went well! Best wishes with school!

[@jennifers6823]

Thank you so much, I’ve been wasting my time reading my textbook.

[@xiaoligong6670]

You made it so clear!! Just one question, I saw some of mutators start with public void set instead of void set, why is that?

[@TechnicalCafe]

If you're referring to the video, I'm not certain as to why I would have done that. However, not including an access modifier like "public" for a method would cause the method to have the "default" access modifier, which is similar to the "public" modifier, but with a few restrictions. Here's a link that explains the difference between the "public" and the "default" access modifiers in more detail: www.geeksforgeeks.org/access-modifiers-java/.

[@nurishqashrinabintimohamad655]

sorry everyone, it might silly question.. but why we have to do all this with 2 files? i mean we usually compile all of those in 1 file right?

[@michaelgonzalez2521]

how would the balance var get updated?

[@TechnicalCafe]

+Michael Gonzalez The "balance" variable would be updated using a mutator (getter) method. In this video, I used the example of a setBalance() method, but you could create as many mutator methods as you'd like to change the value of the private "balance" instance variable. Some other example mutator methods that you might want in the "BankAccount" class might include "Deposit()" or "Withdraw()" methods. I hope this helps to answer your question! Please don't hesitate to reach out if you have any other questions, comments, or suggestions! I'd be happy to try and help where I can! Thanks for watching!

[@focusaddiction3460]

I still don't get the point of doing this instead of changing the variable directly without the acessors. Both will change the variables, won't they? What's the point? I know there is one, but i can't understand it.

[@shreyapandey2372]

Focus Addiction i am also confused you are still able to see and access the data using get and set method so what's the point I don't see it as data being secured here

[@shreyapandey2372]

muhammad yasin but aren't get and set public methods? That should allow everyone to set variables , how are they protected ?
