利用字节码文件的对象，调用构造器：

        package com.Reflect;
        //利用字节码文件的对象，调用构造器
        import java.lang.reflect.Constructor;
        import java.lang.reflect.InvocationTargetException;

        public class Demo02 {
            public static void main(String[] args) throws ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {
                Class aClass = Class.forName("com.Reflect.Demo01");
                //declaredConstructor可以调所有的运行构造器
                Constructor declaredConstructor = aClass.getDeclaredConstructor(String.class,double.class,int.class);
                Object o = declaredConstructor.newInstance("小明", 186.8, 120);
                //constructor可以调用有参构造器
                Constructor constructor = aClass.getConstructor(String.class, double.class, int.class);
                Object o1 = constructor.newInstance("小红", 175.3, 110);
                System.out.println(o);
                System.out.println(o1);
            }
        }
