写一个方法，此方法可将obj对象中名为propertyName的属性的值设置为value.

    public String toString() {
            return "Person[name=" + name + ", age=" + age + "]";
    }

}
//Exception in thread "main" java.lang.NoSuchFieldException: dsd  
Field field =clazz.getDeclaredField(propertyName);  这行报错 ，，，请教下高人

版主已经回答你了， getDeclaredField()  参数里是字段的名称 要传字符串的
