First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a typical three-layer switch, the communication between broadcast domains is usually impleme
java keyword This, super use summary First, this The Java keyword This can only be used in a method method body. When an object is created, the Java Virtual Machine (JVM) assigns a pointer to the object that refers to itself, which is the name of this pointer. Therefore, this can only be used in non-static methods in the class, static methods and static code blocks must never appear in this, which is explained in the article "Java keyword static, fin
First of all, we have a question about the Python super class in StackOverflow as the beginning of this article, the problem is basically this:>>>classA (object): ...def __init__(self): ...Print "A Init"... super (a,self) .__init__()... >>> >>> A =A () a init>>>classB (object): ...def __new__(self): ...Print "B New"... super (b,self) .__new__()... >>> >>> B =B ()
Java Object-oriented-–super keywords
1: Define father (parent Class) class
1: member variable int x=1;2: Construction method without parameter and argument, with output statement
2: Define son class extends Father class
1: member variable int y=1;2: The construction method is non-parametric and has a parameter. have output statement this.y=y+x;
3: Create son class object
Son son=new Son(3); Sy
Like what

Reply content:For your question, the answer is yes, and there is no difference. But I don't feel good enough to answer the question.
To talk about super, first we should ignore the interference of the name "Super".
don't talk about super when you think of the parent
outercls.innercls ();
}
}
Class outercls{
public static Class innercls{
Innercls () {
System.out.println ("Innercls");
}
}
}
The output will be as you expect.
Innercls
Same as the ordinary class. For other uses of internal classes, refer to the relevant chapters in the "I" Java, which are not detailed here.
Second, this super

Intel has recently been exerting its power at the channel end, and the computer stores, 3C stores and the manufacturers of the manufacturers have been pushing the pole. However, in the face of "super extreme" this jerky vocabulary, a large number of users do not understand their meaning. Many consumers think "ultra-extreme" means super lightweight and super perfo
Super is used to solve multiple inheritance problems, it is not a problem to call the parent class directly with the class name when using single inheritance, but if multiple inheritance is used, it involves various problems such as lookup order (MRO), repeated invocation (Diamond inheritance). In short, the experience left behind is: to maintain consistency. Either call the parent class with the class name, or use
Note: python3 is the runtime environment. The example is taken from Chapter 8th of pythoncookbook. In python, there are two main methods to initialize the parent class if the subclass is to be implemented. The first method is to directly use the parent class name, and the second method... quot; gt; lt; metaname quot; keywords quot; content quot; call details of pythonsuper in multi-inheritance. note: python 3 is the runtime environment, the example is taken from Chapter 8th of python cookb
Summarize the keyword this and the super usage. AUTHOR:ZJ 07-3-12blog: [Url]http://zhangjunhd.blog.51cto.com/[/url]1. What is super? What is this? The Super keyword denotes the meaning of the super (parent) class. The This variable represents the object itself. 2. Use Superthis to call member variables and methods you
Two special variables in Java: this and super -- general Linux technology-Linux programming and kernel information. The following is a detailed description. There are two very special variables in Java: this and super. These two variables do not need to be declared before use. This variable is used inside a member function and points to the current object. The current object refers to the object that calls
When the subclass needs to call the method of the parent class, before python2.2, call the class's method directly with the class name, that is, the non-binding class method, and the self of the object is passed in the argument.
Class A (object): def Say (self): print ' I am A ' class B (a): def Say (self): print ' I am B ' A.say ( Self) B = B () B.say ()
Output
I am BI am A
This works fine, but there is a problem, when the parent class changed the name, it is necessary to
Think of Python's super () function, pythonsuper

Thought of by the super () function of Python
First, let's take a look.super()Function Definition:
super([type [,object-or-type]])Return a **proxy object** that delegates method calls to a **parent or sibling** class of type.
ReturnsProxy objectThis object
wrong, hehe.Third, in the function, it is necessary to refer to the current object of the class that the letter belongs to, directly with this. In fact, these usage summary is from the "This is a pointer to the object itself" this sentence of a deeper understanding of the word, rote or easy to forget and easy to make mistakes, to understand! second, Super Super key is similar to this, is a masked member va

Generics are added in Java 1.5, and the details of generics are not discussed here, which is very clear in the fourth edition of Thinking in Java, which is about the super and extends keywords, and why there are different limitations when using these two keywords. First, we define two classes, A and B, and assume that b inherits from a. The following code, which defines several static generic methods, is not particularly well-written, and we mainly co
