2、动态创建对象
clz.getConstructor().newInstance()

public class server {
public static void main(String[]args) throws ClassNotFoundException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException, SecurityException
{
//三种方式获取class对象
//1、对象.getClass()

    Class clz=new iphone().getClass();
//2、类.class()
    clz =iphone.class;
//3、Class.forName("包名.类名")
    clz=Class.forName("cn.sxt.oo.iphone");

    //创建对象,用构造器
    iphone ip=(iphone)clz.getConstructor().newInstance();
    System.out.println(ip);
}

}

class iphone{

public iphone()
{

}
}
