Maaan! I just saw the official Video from google “Data Classes - Kotlin Vocabulary “ and was good but I still did not fully get it. I instantly searched “Data Class” in your channel and your video helped me a lot! 💪🏻😃 Would be cool if you can create videos based on Android Dev Channel with the Simplified Coding touch!! Keep up the good work 🙏🏻❤️

@vikramsinghnegi1559 2 года назад

A fruit full thanks to you sir for this beautiful tutorial. But I have a question. Why kotlin compiler generates componentN methods instead of just using getters? If you check out decompiled kotlin bytecode you'll notice that componentN methods and getters are exactly the same. Please answer. It's my humble request to you sir.

How to add vfx effects to our apps like making vedios or photoeditings

@AlaaAlbrg 3 года назад

The component part is not very clear, why you comment the all the print(person.componentX), and what are those useful I didn't get it?

@SimplifiedCoding 3 года назад

for all the variables available in the constructor of your data class, a function named componentN() where n is the number. component1() will return first paramemter component2() will return second parameter . . componentN() will return Nth parameter. Hope you understood now.
