We cannot decide to inherit different objects during the run.1), pure inheritance and extension. Pure inheritance: Only methods that have been established in the base class can be overridden in the
Java enhanced for loop is very usefulCopy codeThe Code is as follows:For (String str: list ){System. out. println (str); // Where str is directly an element in the Set} However, the for/in loop provided for us in JavaScript is no longer that simple.Copy codeThe Code is as follows:Var carVar garage = new Array ()Garage [0] = "BMW"Garage [1] = "Mercedes-Benz"Garage [2] = "Bentley"For (car in garage){Document. write (garage [car] + "")}// Output result:
implement only the methods declared in the interface and the abstract class, and should not give redundant methods.What is "upside down"?What is "inverted", to understand it, let's look at the right place. Relying on the positive is the dependency between classes is a real implementation of the dependency between classes, that is, to implement programming, which is the normal way of thinking , I want to drive Mercedes-Benz rely on
First, the PrimerTen years ago, there was an upstart who had three cars---Mercedes-Benz, BMW BMW, Audi Benz, and hired a driver to help him drive. But the nouveau riche is always a strange ride: After the Benz with the driver said "drive Mercedes!" "When he was in BMW, he said," Drive a BMW! "Take the Audi and say," Drive the car! ”。 You must say: this man is sick! Why don't you just say drive?!And when we

I want to the install daytime running lamp (DRL) on my W164. It has advanced fog lights and they turn on when you turn the wheel. When I Activate day running Lights (in SAM module) it turns the low beam light on. Using Star diagnosis, I changed low beam to fog lights, but it again turns low beam on.After a long-time searching in the Internet, someone told me, Canadian Mercedes DRLs can be activated via Star Diagnos is, no sure if US cars would do. And
Principles of design patterns:Programming with excuses
The role of the factory model:
A. In application design, object creation is concentrated in one place or managed by a certain class (spring)
B. You can directly add objects without modifying the application, which is also conducive to object maintenance.
Types of factory models:
A. Simple Factory
B. Factory method
C. Abstract Factory

I graduated from college in a city and now. Every time I went out, I took a bus. Everyone knows that we can see three directions in our eyes while sitting on a bus, generally, there are few bus seats that allow you to directly see things behind you ....
In the past two years, every time I take a bus, I can feel the development and changes of this city. The number of famous cars, such as Mercedes-Benz and BMW, is growing. I always think that I will
The simple factory model is one of the factory models. There are three factory models: the simple factory model, the factory method model, and the abstract factory model, that is, all object creation tasks are handed over to the factory. From the simple factory mode to the abstract factory mode, the abstract level gradually increases.
The factory model consists of three parts: the factory role, the abstract Product role and the specific product role.
The factory role is the core of the factory m
Following the delisting of the first 45 Mercedes-Benz taxis by the end of July, the remaining 55 "great Ben" have all said goodbye to the taxi operation market of this city by the end of September.

" status, it is "anti-monopoly ". Therefore, using pirated software, especially in China at present, is justified because piracy is "Broken (Microsoft, or include software vendors that are in the "hegemony" status ". To be honest, this is to break the monopoly in the market. To be honest, it is also related to the national and national cloud. It is a pity that anyone who understands Economics can understand the so-called "piracy can break monopoly" and other comments with a little analysis.

If we want to model the concept of "car", it has four attributes: name, head, body, and rear ).Object-Oriented Approach
First, we define a car class:
Public class car {Public string name;Public String head;Public String body;Public String rear;
Public Car (name, head, body, rear ){This. Name =
1 Package Cn.bjsxt.array; 2 3 Public class Car {4 String name; 5 // Construction Method 6 Public Car (String name) {7 this. name=name; 8 }9 }1 Package Cn.bjsxt.array;2 /**3 * Array reference type you can be the object.4 * @author Administrator5 data is a collection of the same data type (any type)6 The array is also an object, and the array element corresponds to the object's member variable7 The length of the array is deterministic and immutable.

With respect to an array of string types, the array element does not need to be added ""
Today, in writing swing, for a quick layout, you need to create a string layout array as shown:
Careful readers may find that the array elements in this border array are not in "", and we know in the learning array that when we define a String array, the elements of the array need to be included in "", for example, we define an array string[]car={"BMW", "Mercedes
