说明：  Java是一门面向对象编程语言，不仅吸收了C++语言的各种优点，还摒弃了C++里难以理解的多继承、指针等概念，因此Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式进行复杂的编程。
(Java is an object-oriented programming language. It not only absorbs the various advantages of the C++ language, but also eliminates the concepts of multiple inheritance and pointers that are difficult to understand in C++. Therefore, the Java language is powerful and easy to use. As a representative of static object-oriented programming languages, the Java language implements object-oriented theory very well, allowing programmers to perform complex programming in an elegant way.)
