Before I start to see a puppy, let's take a look at a simple question:What the output of the following program is.
If your answer is "Xiao Qiang", good, congratulations you are correct. Now let's change the code:
Yes, I just added a code to the ChangeName method.
What is the output this time?
A prosperous fortune

The answer is a prosperous, changename method did not change the name of Mydog. If you're wrong, it doesn't matter, I'm going
Before I start looking at the puppy, let's look at a very simple topic:What is the output of the following program?New Dog ("Mong Choi"); ChangeName (Mydog); System.out.println (Mydog.getname ()); Public void ChangeName (dog) { dog.setname ("Xiao Qiang");}If your answer is "Xiao Qiang", well, congratulations on your correct answers. Let's Change the code:New Dog ("Mong Choi"); ChangeName (Mydog); System.out.println (Mydog.getname ()); Public void

There is also a caveat that when you use the arrow function to return an object, always enclose the returned object with parentheses:
Create a new empty object for each puppy to play with
var chewtoys = puppies.map (puppy => {}); bug!
var chewtoys = puppies.map (Puppy => ({})); OK
//Create a new empty object for each
link of the object, processing a target, will be processed in the previous link to the image of the next target to deal with, called the Gpuimage processing chain.
The target of intermediate links is generally a variety of filter, is Gpuimagefilter or sub-class.
The final link target, Gpuimageview: Used to display to the screen, or Gpuimagemoviewriter: written in a video file.

Oh Great, the letter came in a timely manner, and if I continue to do so, I will be crushed and have to find another job. Well, this time I'm going to write this plan well. In this way, the burden of the body has finally eased hope. With the recognition of my boss, I want to make a grand exhibition. Graphicaleditpart involuntarily patted him
Python class, Python1. Create and use classes
The class can simulate almost anything.1.1 create a Dog class
Each instance created based on the Dog class will store the name and age. We have given each puppy the ability to squat sit () and roll roll_over ().

Note: It is usually necessary to override this method when it is overwritten.HashcodeMethod to maintainHashcodeMethod, which declares that the same object must have an equal hash code.
Parameters:

Return Value:

multiple methods, in the example above, barking (), hungry (), and sleeping (), are all methods of the dog class.Construction methodEach class has a constructor method, and if you do not explicitly define a construction method for the class, the Java compiler will provide a constructor method for the class.When creating an object, at least one constructor is called, and the name of the constructed method must be the same as the class, and a class can have more than one constructor method.The fo

the gaps between the two buildings.
When the width of the gap is larger than that of a certain soldier, this soldier can pass through this gap, and vice versa.
Take puppies as an example. We need to find out which building combinations have a gap smaller than the puppies.For example,The gap width between AB is (1 + 1.5) * 32-26-40 = 14The gap width between BC is (1 + 1.5) * 32-22-32 = 26The size of a puppy is 15, soWhen the House is above the barrack
a static keyword.
Classes can be accessed by any number of methods to access the values of different kinds of methods. In the example above, barking() hungry() and is the sleeping() method.Four, the constructorEach class has a constructor. If you do not write a constructor for a class individually, the Java compiler will create a default constructor for the class.Whenever a new object is created, at least one of the constructors will be called. One of the main tenets of the constructor is
This example uses the new "skeleton Tool" in Flash CS4 to create a reverse motion that can produce complex and natural animations in a short time, which is ideal for use in shadow animation.
This case thinking
Import the footage, and then divide the elements of the graphic into pieces.
Use "Skeleton tools" to add good bones to the elderly, and then make walking animations for the elderly.
Use the Skeleton tool to add a good skeleton to your puppy,
Constructors
Each class has a constructor.
If we do not write a constructor for a class individually, then the Java compiler will create a default constructor for the class.
Whenever a new object is created, at least one of the constructors will be called.
One of the main tenets of the constructor is that they must have the same name as the class. A class can have more than one constructor.
Demo of a constructor:1 Public classPuppy {2 PublicPuppy (String name) {3S

In OOP, we use a lot of programming like the above to abstract, inherit, encapsulate, and polymorphic classes to achieve the reusability, flexibility, and extensibility of programming. But this kind of programming still has certain limitation, sometimes, OOP does not solve the problem that we encounter in the actual development again. To illustrate the problem, look at the following illustration:
