java反射，,利用java反射方法设置

利用java反射方法设置属性``` javapackage com.baobaotao.reflect;

import java.lang.reflect.Constructor;import java.lang.reflect.Method;

/* * Created by xu on 2016/7/4. /public class ReflectTest { public static Car initByDefaultConst() throws Throwable {

    //1.通过类装载器获取Car类对象    ClassLoader loader = Thread.currentThread().getContextClassLoader();    Class clazz = loader.loadClass("com.baobaotao.reflect.Car");    //2.获取类的默认构造器对象并通过它实例化Car    Constructor cons = clazz.getConstructor((Class[])null);    Car car = (Car) cons.newInstance();    //3.通过反射方法设置属性    Method setBrand = clazz.getMethod("setBrand",String.class);    setBrand.invoke(car,"红旗CA72");    Method setColor = clazz.getMethod("setColor",String.class);    setColor.invoke(car,"黑色");    Method setMaxSpeed = clazz.getMethod("setMaxSpeed",int.class);    setMaxSpeed.invoke(car,200);    return car;}public static void main(String[] args) throws Throwable {    Car car = initByDefaultConst();    car.introduce();}

}
