Watch now to learn the difference between ".equals()" vs. "==" in Java. Full tutorial on the difference between "==" (double equals) and the ".equals()" method in Java. Especially for Strings, when do you use ==, and when do you use .equals?
Simple equality checks in Java can be tricky, but the facts are simpler than you may think.
This is a very beginner friendly beginner's Java coding lesson tutorial, where we'll discuss the difference between == and .equals() when doing equals checks in Java.

so far I've watched several videos with the same topic but this video only explained well. Thanks man!
Awesome! Very glad I was able to help!
Oh my god I'm genuinely so thankful I discovered this Channel, John explains stuff like no one else does, you just earned yourself a subscriber mate, thank you for all the efforts.❤
Feeling lucky to have found this channel, I've been self studying on and off for a couple years and I'm pretty sure I should have known these key concepts by now, sincere thanks for these clear and understandable teachings!
OMFG please keep your content comming...im having a blast learning from you man. Im deeply grateful for all your lessons.
Really fascinated at how good you are able to explain. Thanks for the great video!
Simple and easy to understand. Thank you!
These are beautiful videos man 😁 Every sentence of yours resolves an issue I had and leads to the next question I had. So helpful ! Thanks 🙂
I'm a newbie dev and I finished a bootcamp but your videos topics are all the topics I found confusing during class and always wondered about. TY so much.
go away bootcamp people
Hi John you did very well in this lesson. I tried to learn .equals and == from a professor but I couldn't understand it and now I got the point from you in 5 minutes.
wow this goes well with your string pool video. Thanks for making these really comprehensive videos on how java works for the basic things we just usually use without thinking about.
Warning ⚠️ : If you are going to override .equals method,you have to override your hascode method. Otherwise there will be a mess with those objects whenever you hashing
That was incredibly well explained! Thanks a lot!
I just found your channel and the world just makes so much more sense now.
Had been scratching my head on a case similar to the example at last, luckily this video explained it. Huge thanks :)
Thanks John, your tutorials are very helpful. You are a great teacher, hats off!
tus videos tienen un gran valor, muchas gracias por compartir tu conocimiento
this channel always dropping gems. Respect.
This actually helped me understand why some of the code I was writing was initially breaking. Ty!
I got back into Java recently after not using it for like 8 years and have been haphazardly using == for strings and it has been working, presumably because I have been always using strings as state variables in games, and so have been manually typing the strings in my conditions as literals (if (facing == "up")) etc.
I saw a comment on another video and I'm glad I found this early enough to refactor everything. haha.
Ah Lord! can't just say how easy you explained it. I have been really confused for several days about this simple .equals in object class and now I know how java processes it. Thank you so much for this video. Subscribed liked and commented. Keep up with your good work!!!!
I just bought his full Java course. Amazing explanation .
Thanks for the video john seems like refreshing my basics
Very well explained Jonh, Thanks again ♥
Great video as always. Thank you for your dedication!
John, this was an amazing tutorial!
I had a query though; on the objects, do we override the equals() or is it inferred?
we override it
6:15
Love the Kramer picture in the back, my grandpa has one just like it! Thanks for the amazing videos!
Thanks John, your tutorials are awesome.
This is awesome! Can you do a video on priority queues and comparators, and how they come together?
the last part was really good!
Thansk's John. Please don't stop your videos they are awesome
Thanks so much for the video. Genuinely looking forward to the "how to write a good equals method" vid!
thanks a lot you help me to understand the concepts
This is just the best explanation..wow👏Thank you for all your videos🙏
Thanks John, Mucha Gracias from Canada!
Easy to understand. Thank you.
This guy is the best as a learner and teacher guide
Love your videos bro. Very helpful. Thanks a lot
Thank you so much, your videos are pretty helpful 😊
Very clear. Awesome examples and also my eyes love the dark theme ^^
Thx for your clear presentation Sir
Great lessons as usual. Thanks.
This is the best i have understoon so far...
I wish you were my lecturer at Uni. You have talent man!
By the beard of Zeus! Your contributions to the world of programming are nothing short of epic. Your Java beginner's playlist is truly a stroke of genius, and I speak for many when I say, you are the real MVP!
Thank you so much.. Your explanation is very clear...!!!
Wow, noob here, didnt know those details till you explain it, massive thanks John!
Thanks! Your videos are great!
wow, very well explained. Thank you
Excellent video as always!
This channel is very very good.
Wow thanks man it is so well explain !
I'm glad I've found this chanel. I've never been more educated by any other escaped convict in my entire life! Keep it up! :)
😂😂
It seems I've found my coding channel. Thanks for the video :)
thank you, sir. !! great explanation.
I love this guy! I am hitting the Like button!
Good explanation! What about enum comparation? What should I use?
Very interesting ,thank you .
Might also be worth mentioning that you can use == with enum's as well.
Amazing explanation, thanks alot
thank you so much! very helpful!
Just the greatest explanation !
thanks a lot !!! awesome explanation
Thanks John!
These videos are great! But you should have included a video on how to implement the .equals-method and compare-to method to your own class
You are great. Congrats for channel and being Team Leader. Maybe you could/should make a video talking about what should a junior know. I think i know equals now, exceptions/throw/finally/catch etc, im learning generics and i undertand but i saw a generic method in an interview(company was about HR, and i was asked 4 Design Patterns which i knew but wasnt good enough for company anyway) i had no idea what it was even if i knew generics it was kind of pro code/ultra weird and hard i think it was with lists btw..i also hate leetcode i prefer videos like yours to actually learn java. I would also learn more from you cause you good and you enjoyable i hope you do the same in your job irl. i think i also know most of collections hashmap/set etc
John, where did you get the source and how did you attach the source to the binaries? UPDATE: solution is to point your JRE path to the path with the JDK instead!
Nice job John !
Amazing tutorial!
Once you learn a thing or two about oops you know exactly what's going on. Thank you for the video
Thank you John
This is a very useful video.
Your tutorials are awesome! Though I wonder if this affects switch cases too. Can I always use switch cases or do I need to be cautious just like with the == operator?
love your videos man !
lmao, that head pop up at the beginning cracks me up!
Small piece of feedback: title shoulda been ".equals() and == are not equal"
Thanks for the great video!
.equals() != ==
@@CodingWithJohn even better!
Good stuff brotherly.
I love your videos, thank you
To the point explanation
Superb sir❤
Perfect concept
Cristal clear!
Hey pls make video on comparable comparator interface in java
Excellent teacher
Thank you john!!
The underline is even if the primitive or non primitive or user defined type java will check for the memory location and not the values.. (if the values are same then uses same memory location).
Best tuto ever
Great lesson :)
Thank you sir.
John, please clarify this for me, in text, how would you declare and compare 2 string objects for equality?
You explained sth in 8minutes that my French prof couldn’t explain in 2 hours and made me hate Java for no reason . Thank you ❤
Thank you
ThankYou!!!
dude, your videos are amazing
I am going through you video and its very easy to understand . One more request can you please provide session for Stack vs heap memory.
Can you do a video sometime on instanceof, thank you.
Can you please make that video you promised on writing a good equals method?
You are a genius!!
Really Really cool!
Thank you so much
Thanks. Useful, however you still did not cover how to compare 2 objects on the Dog example staring from 05:08
The API contract also states that if you override equals() then you must override the hashcode(), it's an important detail!
