51: invokevirtual #70// Method java/lang/Class.newInstance:()Ljava/lang/Object; 3.使用Constructor类的newInstance方法 和Class类的newInstance方法很像, java.lang.reflect.Constructor类里也有一个newInstance方法可以创建对象。我们可以通过这个newInstance方法调用有参数的和私有的构造函数。 Constructor<Employee> con...
This calls one ofRectangle's constructors that initializesorigintooriginOne. Also, the constructor setswidthto 100 andheightto 200. Now there are two references to the samePoint object—an object can have multiple references to it, as shown in the next figure: The following line of code call...
Class对象可以获得该类里的方法(由Method对象表示),构造器(由Constructor对象表示)、Filed(由Field对象表示)、这3个类都位于java.lang.reflect包下。并实现了java.lang.reflect.Member接口。程序可以通过Method对象来执行对应的方法,通过Constructor对象来调用对应的构造器创建实例,能通过Field对象直接访问并修改对象的属性值...
