Java abstraction 👻

Missed classes because I was sick and your videos helped me so much in so little time. The best 🙌🏼

[@funkyliani]

I started learning Java through an online course, which is terrible at explaining things, leaving me confused lot of the time. Then comes BRO, who explains everything so simply and elegantly that I have no problems understanding it! Thank you BRO!

[@mohammadreza1414]

Your videos gives everyone a very clean start. This is great because we can easily build on that using other resources.

[@laurahanna5228]

Honestly, your videos are saving me this semester. You explain it better than my professor, thank you for making content like this.

[@ericbiscayne6722]

Bro; you have no idea how much you've helped me so far to learn Java. Any doubts I come here, looking for an example that you have,no doubt thank you, sincerely. - Never thought a bro' would save my ass this way. Love you and admire you.

I have been avoiding any instance that would make me use abstract classes cos the articles I read before never explained it clearly but I think this is the safest way to me now. I have been creating classes and just making things simple by using access modifiers, but yeah, thumb up Bro.

[@PetiteKero]

I LOVE these explanations, the example with the dealership and the vagueness was extraordinary. 💙 Just one thing that's still keeping me from fully diving into everything: I sometimes miss the practical use. Why would I wanna prevent somebody from instantiating the abstract class? Why do I need to send values to a constructor and not just use the Main class? Any idea how to untie this knot in my brain (which lets me think a miss the very basics of Java)?

[@soumelee5661]

[@Gabriel-xq6tn]

Good explanation. Do you need to have a regular method inside an abstract class since an abstract class cannot instantiate objects?

[@arkamukhopadhyay2177]

Sir, I have two questions: 1. Can an abstract class have a normal (non-abstract) method? 2. Can a normal class have an abstract function?

[@BroCodez]

Hello Arka! Good questions 1. An abstract class will need static methods since we cannot create an instance of an abstract class 2. A normal class cannot have abstract methods

Wait but what's the difference between this and just making the methods in the classes you need them in in the first places? If you just override an abstract(useless?) method

[@marbles5590]

Great video! For the ones out there who are quite confused with the given example, another similar code snippet is like this: //Vehicle(superclass) //Bike, Car, Boat (all are subclasses and uses the extends keyword) Vehicle a = new Car(); Vehicle b = new Bike(); Vehicle c = new Boat(); Vehicle[] test = {a, b, c}; This is much more understandable and less confusing for some. However, if there's a unique method present on one of those three subclasses above (for example, like void printCarModel() in the Car class only) that is NOT present in the Vehicle superclass, you would need to use the example code shown in the video. If we try to access the printCarModel() method: a.printCarModel(); It would result in an error since the type of 'a' is 'Vehicle' and not 'Car' (because we did Vehicle a = new Car(); and there's no such printCarModel() in Vehicle) Use: Car a = new Car(); instead to access that unique method.

[@suhailraja7797]

You could also typecast the vehicle into a car to access the method I also have one question that I'm confused about abstract classes What's the point of them? In this video he said it's to add a further layer of security to prevent someone using too vague or broad of a class and trying to make an object out of that but can't you just solve that by not making that class at all Is it because we need the superclass because it makes writing subclasses quicker because we can just use the super keyword to access all the general shared information that the subclasses have with the superclass, that way it encapsulates code more or are there any other reasons
