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,或
* @return The {@code Class} object that represents the runtime * class of this object. * @jls 15.8.2 Class Literals */publicfinal native Class<?>getClass(); 这是一个final类型的native方法,也就是说这个方法不能被子类重写,同时它的实现并不是通过 Java 语言实现的,而是用其他语言(C/C++)实现...
