In Java, a class serves as a blueprint or template that defines the structure, behavior, and attributes of objects. It acts as a logical entity encapsulating data and methods. A class can be considered as a user-defined data type, enabling the creation of multiple objects of that type. Fo...
我们都知道所有的java类都是继承了object这个类,在object这个类中有一个方法:getclass().这个方法是用来取得该类已经被实例化了的对象的该类的引用,这个引用指向的是Class类的对象。 我们自己无法生成一个Class对象(构造函数为private),而 这个Class类的对象是在当各类被调入时,由 Java 虚拟机自动创建 Class 对象,...

注意:Class对象由JVM自动创建,编程人员无法通过API直接new对象. 对象克隆: (1) 概念:Object.clone():创建当前对象的副本;前提条件:实现的Cloneable接口 (2) 意义:简化对象的拷贝,通过JDK平台统一一个对象副本的创建方式. (3) super.clone():是java本地的方法,通过虚拟机JVM内部机制自动完成对象内容的复制。
