Classes In Java Language The class is the fundamental programming unit of the Java programming language. (类是Java 语言的基本编程单元) Classes provide the structure for objects and the mechanisms to manufacture objects from a class definition.(类提供了对象的结构,可以 根据类的定义创建对象) Each object is an instance of a class.(每一个 对象都是某个类的实例)
Programming Languages As difficult to discuss rationally as religion or politics. Prone to extreme statements devoid of data. Examples: \It is practically impossible to teach good programming to students that have had a prior exposure to BASIC; as potential programmers they are mentally mutilated beyond hope of regeneration.\(Dijkstra)
