Watched all 30 of your FREE Java for Beginner videos. Great work, Marcus! 💯

Hi Marcus, great class! I always use immutable objects especially in my DTO's, like writing my views with DTO's, as I have no set methods the actual data value that enters the inputs is the real value that comes in the controllers. This seems perfect because we prevent the data being manipulated.

I have two challenges in life, becoming fluent in English and learning Java. I currently do this at the same time.

Thanks, this is really helpful Mr.Biel.
Does the word "stable" mean "resistant against changing" and thus "resistant against getting into a wrong state" in your video?

Thanks, great video! My question is: After you have created a lot of immutable instances of the same bank account, how do you know which is the actual balance, taking into account concurrency issues?

Great explanation! Really enjoyed that. Is the craftsman drawing of you?

Have to be careful with immutables as if not used correctly, memory can be affected. It really depends on the type of system that you're designing..

I faced this question in interview panel.... Thanks

Thanks for the video :)

This works great for simple classes, but do you have thoughts on how to construct an abstract class that is (if at least only by trust) immutable?

One of the really big benefits of Java is it's extensibility, which a common abstract class aides. However, without trusting a factory passed to this common abstract class to always (scouts' honour) return a brand new object, I haven't thought how to achieve this yet...

Hello Marcus, is this the same as The creational pattern --> immutable objects pattern ?

You speak very slowly. It drags the video out unnecessary and thus makes the video more boring and uninteresting. You should try increasing the tempo
