We all know that this and super call constructors must be placed in the first sentence, and today the classmate asked me a question of a little meaning.So: How do I explicitly initialize a parent class with super in a subclass and initialize the subclass with this? -------------------------------------------------------------------------------------First of all, we must realize that two points:1. The

* SUPER () and this () are similar, except that super () calls the constructor of the parent class from the subclass, and this () calls other methods within the same class.4. The similarities and differences between Super and this:1) Super (parameter): Call one of the constructors in the base class (should be the first

Http://www.cocoachina.com/macdev/objc/2011/0124/2602.html In the class implementation of objective-C, we often see the two keywords "self" and "super". Taking the previous OOP language experience as an example, C ++ assumes that self is equivalent to this, super is equivalent to calling the parent class method, which seems easy to understand. BelowCodeFor example: @ Interface person: nsobject {Nsstring

While looking at the Python Advanced Programming book, when it comes to super, there's some confusion about how super's usage in Python is different from other languages, finding some information on the web and finding that basically few articles can make my doubts clear, One of the most valuable things about this article is that it explains how we use the super right way.First look at a program:classA:def

What is the difference between super () and this ()? This () invokes the parameterless constructor of the current object, and super () calls the parameterless constructor of the parent class1) Super (parameter): Call one of the constructors in the base class (should be the first statement in the constructor)2) This (parameter): Invokes another form of the constru

by defining a method or member with static, it provides some convenience for our programming, which in some way can be said to be similar to global and global variables in the C language.(It's a global variable that's understood to be static) but it doesn't mean you can use it anywhere, and if that's the case, you need to think about whether you're programming with object-oriented thinking and whether your program is object-oriented. Okay, now we're going to talk about the meaning and usage of t

In Java, this usually refers to the current object, and super refers to the parent class. When you want to reference something of the current object, such as a method of the current object or a member of the current object, you can use this to achieve this purpose. Of course, another purpose of this is to call another constructor of the current object, which will be discussed soon. If you want to reference something of the parent class, it is not

1.thissuperWhat is This,this is an object of its own, representing the object itself, which can be understood as: A pointer to the object itself. When you want to reference something in the current object, such as a method of the current object, or a member of the current object, you can use this for this purpose. Note that this can only be used in non-static methods in the class, and the static method and the static code block must never appear in this. His can also be used as a constructor fun

This paper analyzes the difference between PHP global variable and super global variable. Share to everyone for your reference, specific as follows: A global variable is a variable defined outside the function. cannot be used directly in a function. Because its scope does not go inside the function. So the global $a is often seen when used inside functions; The scope of the Super global variable is valid
