1. Preface: Java is a typical object-oriented programming language, but there are 8 basic data types that do not support object-oriented programming, the basic data types do not have the characteristics of objects, no properties and methods ; Java

The go language object-oriented programming is simple and clean, through the non-intrusive interface model, the need to negate the complexity of traditional object-oriented programming languages, such as C/C + + Java, we find that even a simple

Wrapper classes for basic data typesWhy do I need a wrapper class? Java is not a purely object-oriented language. The Java language is an object-oriented language, but Java's basic data types are not object-oriented. However, we often need to
