SmalltalkThis is the first successful object-oriented programming language and the basic language of Java. The five basic features of Smalltalk (Java's base language):(1) Everything is an object. The object can be imagined as a new variable; it

Five characteristics of objects(1) Everything is an object. The object can be imagined as a new variable; it holds the data, but it can require manipulation of itself. Theoretically speaking,All conceptual components can be presented from the

Easy Learning of JavaScript 12: JavaScript Object creation based on object-oriented (1) This time, we will take a deeper look at the JavaScript object-oriented technology. Before learning, we need to explain some object-oriented terms. This is what

1. When do I use "main extension mode"?There are not many objects, the attributes of each object are different, the properties of each object can be fully determined during the database design phase, and the individual extension objects have

The general use principle of four main design patterns of database design1. Main expansion modeThe main extension mode is often used to extract common properties of several similar objects, forming a "common attribute table", and "public attribute
