First, this usageConcept: This is an object of its own, representing the object itself, which can be understood as: A pointer to the object itself.The usage of this can be roughly divided into three types in Java:　　1. Direct reference to ordinary objects: this corresponds to the current object itself.2. Use this to distinguish between members whose names are duplicate.　classPerson {Private intAge = 10; PublicPerson () {System.out.println ("Age of Initialization:" +Age );} Public intGetage (int

use super in the JAVA class to refer to the composition of the parent class, using this to refer to the current object. If a class inherits from another class, we will have a parent class object in the subclass object when we new the instance object of the subclass. How do you refer to the parent object inside? Using Super to refer to, this refers to a reference to the current object, and

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 class Child (Parent): def __init__ (self): Parent . __init__ (self) 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 In the previous section, we discussed the various uses of static, by defining a method or member with static,

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

I recently encountered some questions about super when I was studying java. At first I saw that super had no idea. I found some information and studied it: In Java, sometimes the member variables or methods in the subclass have the same name as the member variables or methods in the parent class. Because the member variables or method names in the subclass have a high priority, the member variables or metho

This article summarizes the usage of super keywords in Java. There is a reference to the parent class object mentioned in the book. (I have a bit doubt about this statement. If it indicates the reference of the parent class object, it should be said as follows: System. out. println (super); can output the representation of the parent class object. However, the above sentence output is incorrect, while Syste

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 Python-super 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

Super chain: Super Outside the chain is a collection similar to Alexa ranking query, PR query webmaster commonly used to query the site, because these sites are mostly query record display function, and query records can be Baidu, Google, Sogou and other search engines quickly included, so that the formation of the chain. Because this is the normal query generated outside the chain, so this external chain o

A few days ago, one of the brand influence of the "Proud Tour (Maxthon)" Browser completed the version of the update, the grand launch of a new version. The new version of the newly designed page to find the toolbar and the relevant template for Automatic Updates, together with the correction of the dozens of old version of the flaws in the software, the overall functionality and user browsing the overall performance of the Web page has been a very big improvement. The author in the new version

one, in Java, there are usually two ways to use the Super keyword:1. In the subclass of the constructor (initialization), the main call is the default constructor of the parent class, if the parent class has more than one construction method, you can specify a specific constructor by super, such as Super (paras);2. Use a subclass to invoke a hidden or overridden

Note: Python 3 is the operating environment here, and the example is from the 8th chapter of Python Cookbook. In Python, there are two main ways to implement the initialization of a parent class, the first is through the parent class name directly, and the second is to take advantage of the super method. There is no difference between the two in single inheritance, but in multiple inheritance you need to pay attention to some minor gaps. Example expl

Correct understanding and usage of the super function in Python programming, pythonsuper When the subclass needs to call the method of the parent class, before python2.2, the class method is called directly using the class name, that is, the non-bound class method, and pass in the self object as a parameter. 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

this and super are two keywords for java. To clarify a problem first, some people mistakenly think that they are the "attributes" of the object, this can only blame the teacher did not explain the nature of the computer. Because the computer's processor can only use instructions to process data, such as C language, such as easy to understand, is a method call, the data processing. That object-oriented language is actually called by object method Ah, w
