位于java.lang下的Class类是位于java.lang.reflect下的Constructor类、Method类、Field类和Array类的入口类 -Class类 代表一个类 -Field类 代表类的成员变量(也成为类的属性、域) -Array类 提供了动态创建数组、以及访问数组元素的静态方法 -Method类 代表类的方法 ...
Class类的对象内容是你创建的类的类型信息,比如你创建一个shapes类,那么,Java会生成一个内容是shapes的Class类的对象 Class类的对象不能像普通类一样,以 new shapes() 的方式创建,它的对象只能由JVM创建,因为这个类没有public构造函数 /* * Private constructor. Only the Java Virtual Machine creates Class obj...
