super 3ds

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 broadly divided into 3 types in Java:1. Normal Direct referencesThis does not have to be said, this is equivalent to pointing to the current object itself.2. The name of the member who participates in the membership is distinguished by this:Class Person { private int: age = ten; Public person () { System.out.println ("Initialization Age:" +ag

Ext: 52205961The Python language has similar class inheritance to C + +, in which Python customizes the first self, like the this pointer in C + +, to the object itself.Examples of simple Python classes:[Python]View PlainCopy >>> class Hello (object): ... def print_c (): ...print"Hello world!" >>> hello (). Print_c () Hello world! Of course, in practice, the inevitable need for class inheritance, subclasses inherit the parent class, normal as follows:[Python]View

The Python language has similar class inheritance to C + +, and in the class definition, Python customizes the first self, similar to the this pointer in C + +, pointing to the object itself. Examples of Python simple classes: >>> class Hello (object): ... Def print_c (): . print "Hello world!" >>> hello (). Print_c () Hello world! Of course, in practice, the inevitable need for class inheritance, subclass inherits the parent class, normal as follows: >>> class Child (Hell

A brief analysis of new,this,super,final keywords in Java New Keyword For example people person=new people (); create an object what does it do in memory? load the People.class file at the specified location on the hard disk into memory first. When executing the main method, the Main method's space (stack-stack) is opened in stack memory, and a variable person is assigned to the stack area of the main method. Creates an entity space in the heap memo

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

Super piano [Problem description] Little Z is a famous pianist. Recently, Dr. C gave little Z a super piano. Little Z hopes to use it to create the most wonderful music in the world. This super piano can play n notes numbered 1 to n. The beauty of the I-th note is Ai, where AI can be positive or negative. A "superchord" is composed of several consecutive numbered

The definition of an object method in Python is bizarre, and the first parameter is generally named self (equivalent to this in other languages), which is used to pass the object itself, and it is not explicitly passed when called, and the system is automatically passed. Today we introduce the protagonist is super (), in the inheritance of the class super () is very common, it solves the subclass calls the

Super-diamond Configuration management system to provide system parameters configuration management, such as database configuration information, configuration parameters can be pushed to the client in real time (based on Netty4), to facilitate the system to dynamically modify the operating parameters. Multiple projects can be built, each of which is divided into three profiles (development, test, production) to control profile level permi

Introduction: I always thought that the super of OC is the same as the super in Java. I didn't go into its essence until I encountered a situation that could not be explained according to my understanding at work. Analysis:Before that, read the following code:There are two classes: superclass subclass. Subclass inherits superclass and superclass inherits nsobject. @ implementation subclass -( id ) i

with this.Superuse super in the Java class to refer to the composition of the parent class, use this to refer to the current object , and if a class inherits from another class, when we new the instance object of the subclass, there will be a parent class object inside the subclass object. How do you refer to the parent object inside? Using Super to refer to, this refers to a reference to the current objec
