Java extends and implements is my favorite programming language philosophy. It has the same feel as the Python philosophy of extension and implementation, but Java extends and implements is a very different type of implementation in that it is more like a language than a programming language. The philosophy of Java extends and implements is that you should write code that you can’t understand, but the code that you write should be self-describing and self-explanatory.
This philosophy includes a lot of code that you might not know what to do with. For example, I recently wrote a bunch of code that was self-describing and self-explanatory but no one could understand it. This can be a bad thing.
The language you use is just a collection of classes. Java’s Collections is a collection of implementations for Java, and the collections of implementations for all other programming languages. I’m not talking about the whole Java collection, but most of the class collections, among others. This means that you should keep those classes. I’m talking about the collections of all the classes. It can be a collection of abstract classes, and each abstract class has a method that gives a pointer to a superclass.
In java, you can have any number of implementations for any number of classes. If you need to share implementations between classes you can use inheritance. If you need to share implementations between classes you can use delegation. But if you need to be able to override methods in any of the classes, then you need to declare those methods as public, static, or final.
An object is a class. A class is a collection of methods and variables. A method is the body of an object. A variable is the data that gets passed around in your program.
We saw the original video on the YouTube channel, which I’ve watched over and over and over again, and it’s a great example of how to use the class library to use inheritance and object-oriented programming to allow the inheritance of classes. The video describes the process of creating an implementation of a class library that you can use to share classes.
In many cases, what you want to do is to extend the functionality of a class or class library. To do this, you need to define a class, and you need to create a constructor and a method that takes the class and the parameters (like I did in the video). The constructor is like the body of the class. A method is the code that is executed after the constructor. The code that is executed is called the body of the method.
So in order to extend a class, you need to create a constructor, a body, and a method. It should be pretty clear what these are, but sometimes you have to look it up. And that’s where the video comes in.
java is a class that extends the Java class, i.e. it extends the core Java class. But the core class can also be derived from another class. So if you want to extend the java class, you need to create a constructor and a method. It’s not like you create an entity here and extend it, it’s like you create an entity here and write an instance of the java class. And then you can extend that.
Thats pretty much it. Now go ahead and start using java, because you’re going to need it for lots of other stuff.
