These three features optimize object-oriented in many aspects. These three characteristics are also issues that need to be considered when developing object-oriented. Encapsulation in object-oriented What is encapsulation? Encapsulation: Encapsulate abstracted data and operations on the data together. The data is protected internally. Other parts of the program can only operate on the data through authorized operations (member methods). As mentioned above, abstraction is to extract the common attributes and behaviors (methods) of a class of things to form a template (class). This method of studying problems is called abstraction. Just like our bank account, no matter who it is, it includes accounts, passwords, and some common methods, withdrawal, deposit, and query balance. The idea of ??packaging is: & lt;?

# 1. packaging, inheritance, polymorphism entry tutorial: 10 packaging, inheritance, polymorphic zero -based entry tutorial recommendation

##Introduction: The content explained in this section is encapsulation, inheritance, polymorphism, overloading and rewriting. Preface: PHP's object-oriented is the same as JAVA's object-oriented, and they are divided into three major characteristics. , Packaging, inheritance, polymorphism. These three features optimize object-oriented in many aspects. These three characteristics are also issues that need to be considered when developing object-oriented. Encapsulation in object-oriented What is encapsulation? Encapsulation: Encapsulate abstracted data and operations on the data together. The data is protected internally. Other parts of the program can only operate on the data through authorized operations (member methods). Abstraction is mentioned above, that is, a type of thing...

2. What is prototype? Summary of prototype instance usage

Introduction: In JavaScript, you can use the Array constructor to create an array, or use Array literal [], the latter is the preferred method. The Array object inherits from Object.prototype, and executing the typeof operator on the array returns object instead of array. However, []instanceof Array also returns true. In other words, the implementation of array-like objects is more complicated, such as strings objects, arguments objects, and arguments objects are not A...

3. 10 articles about creating arrays in PHP Course Recommendation

Introduction: In JavaScript, you can use the Array constructor to create an array, or use the array directly Quantity[], the latter is the preferred method. The Array object inherits from Object.prototype, and executing the typeof operator on the array returns object instead of array. However, []instanceof Array also returns true. In other words, the implementation of array-like objects is more complex, such as strings objects, arguments objects, and arguments objects are not A...

4. Java array introductory tutorial: 10 Recommended introductory tutorial for zero-based java arrays

##Introduction: Arrays are a type that is found in basically all languages. Data type, which represents a set of data of the same type, has a fixed length, and occupies a continuous space in memory. In languages ??such as C and C++, the definition of arrays is concise and clear, but in Java there are indeed some confusing features. This article attempts to analyze these characteristics. Are arrays in Java objects? Java and C++ are both object-oriented languages. When using these languages, we can directly use standard class libraries, or we can use object-oriented features such as composition and inheritance to build our own classes, and build according to our own...

簡(jiǎn)介：抽象類抽象類不能被直接實(shí)例化。抽象類只定義（或部分實(shí)現(xiàn)）子類需要的方法。子類可以繼承它并且通過實(shí)現(xiàn)其中的抽象方法，使抽象類具體化。你可以用abstract關(guān)鍵字定義一個(gè)抽象類。大多數(shù)情況下，抽象類至少包含一個(gè)抽象方法。抽象方法用abstract關(guān)鍵字聲明，其中不能有具體內(nèi)容。abstract class ShopProductWriter{  ...

9. 總結(jié)創(chuàng)建數(shù)組需要注意的方面

簡(jiǎn)介：在JavaScript中，創(chuàng)建數(shù)組可以使用Array構(gòu)造函數(shù)，或者使用數(shù)組直接量[],后者是首選方法。Array對(duì)象繼承自O(shè)bject.prototype,對(duì)數(shù)組執(zhí)行typeof操作符返回object而不是array。然而，[] instanceof Array也返回true。也就是說，類數(shù)組對(duì)象的實(shí)現(xiàn)更復(fù)雜，例如strings對(duì)象、arguments對(duì)象，arguments對(duì)象不是A...
