不少用户都有这样的感觉:W212 E class前排中控台在车子内饰整体中看来有点怪异:
整个区域显得很空旷,中央扶手箱前面除了导航那颗旋钮和另外几个小按钮之外是一片

但现在换挡杆跑去了方向盘那里,留出这么一大块地方出来,给人感觉就是实际上这个

来自主题: Java版 - 再论abstract class
之前说过我对abstract class的看法,倒是引来不少非议
尤其是有些人居然举出了例子,好,我们就从这个例子开始
有人说在这种情况下要使用abstract class
比如一个animal,有walk和sing方法
那么代码就是
public abstract class Animal{
public void walk(){System.out.println("walk")};
public abstract void sing();
}
然后对于具体的实现类,比如Cat,有如下实现
public class Cat extends Animal{
public void sing(){
System.out.println("cat sing");
}
}
这样一个类,好处就是“便于扩展”等等
OK,那么我们就从这个例子出发,说说为什么在j2ee环境中,我们不这么做
然后说说会怎么做
首先,在j2ee的环境中,关于animal这种实体
我们会在各个层面建立entity

1. All subclasses of the abstract class inherit from the abstract class
There is an 'Is-A' relationship between abstract class and its subclasses

当时在现场看到那个人穿着口袋上印有奔驰商标的衬衫,看样子不像是打酱油的。我上
去一问,果真是MBUSA的工程师。
我问他,很多人都反映E350刹车的时候,车头往下垂,车尾往上抬,有很明显的“点头
”现象。
那位工程师跟我说,因为E class设计的时候是按照出租车的目的来设计的,因此车子
的结构布局、悬挂设计全部都是按照后座坐了两个成人、行李箱放满行李那种情形来考
虑的。因此假如车里只有司机一个人,后尾箱是空的话,头重脚轻,刹车时必然是车头
下垂,车尾上抬。
以上是那个工程师的解释,供参考用。

但是要看到CMG attending 在first class 医院里的增长趋势。如果越来越多的CMG把
自己的努力目标定在first class医院,那么这个胜出率就会越来越多。

我认为不一定。我在国内,算得上是first class医学院毕业,在first class医院一直

之前说到E class设计主要用途是出租车这一点,在很多方面都体现出来。换挡杆那是
一个典型例子了。现在来说一说后备箱。
这里可以比较各车型的数据:
http://www.mbusa.com/mercedes/vehicles/compare/category-OVERVIE
这里列举一下这个级别车子的后备箱容积(cu-ft):
E350:15.9;
GS350:14.3;
535i:14.0;
A6:14.1;
可以看到当其它竞争对手的后背箱还在14 cuft出头这个范围内挣扎的时候,E350就已
经差不多高达16 cuft了。不单止跟同级别相比E class的后背箱出奇地大,甚至跟大型
轿车相比E class的trunk还是巨大的,比如说长轴距S class也才16.4 cuft;而A8则是
仅仅有13.2 cuft,所以毫不夸张地说:E class这个神奇的后背箱甚至比大型轿车A8还
要大得多。
E class这个硕大后备箱的代价就是把后座往前推,所以副作用很明显:这车子后座脚

来自主题: NCAA版 - 我狮2014 CLASS分析总结
我狮最近3个CLASS(2012、2013、2014)个个有事,真可谓多事之秋。2012的CLASS遇
上SCANDAL,JOE PA被FIRE;2013的CLASS遇上NCAA SANCTION;2014的CLASS遇上O'
BRIEN跳槽,FRANKLIN加盟。在这样的非正常情况下,评价CLASS的好坏多了不少变数。
刚签完的这个CLASS,考虑各种情况,我认为可以打A。如果能留住HOLLEY,或者挖来
NICHOLSON这样的孩子,就可以打A+了。具体分析如下:
1、人招满了。这是我认为今年的CLASS最成功的地方。由于受罚,我狮人员奇缺,2013
赛季SPECIAL TEAM全都是WALK-ON,TALENT差距太大,根本没法搞。所以今年足足把25
个名额(20个名额 + 5个EARLY ENROLL,没用GRAY SHIRT)用满是非常关键的,能够尽
可能快的弥补人员的缺口,整体提升DEPTH。
2、补充了我狮目前最大一短板,就是防守后场TALENT和速度匮乏。防守后场包括两个
DB和两个SAFETY,人数很多。而目前我狮的队伍里,我个人认为只有2-3个人够得上BIG

I think you haven't fully understood abstract

you from instantiate a subclass(which is concrete)

来自主题: Java版 - How to use classes in a jar file?
再来问问大小牛们。
我从来没有制作过jar文件,但用过很多别人做的,从来没问题。但是今天自己做了一
个,但是怎么也不行。具体是这样的。
1. 一个月前, 我写了一个程序A作计算。这个程序包括几个classes,都属于default的
package.
2. 这两天又写了一个程序B,也包括几个classes,都属于一个package叫做“
DataManagement”.
3. 今天想把程序A的功能包含在程序B中,于是就把A中的所有的classes放进一个jar文
件叫做“myjar.jar”。这个jar文件本身表面上看不出问题,能够解压。
4.在eclipse里通过"Add External Jars"把“myjar.jar”加入程序B的library里,这
样project的build path里就有了。我以前也是一直这样用别人的jar文件的,从来没有
问题。
5. 在程序B中准备引用“myjar.jar”中的classes,但是不成功,编译总是出错,就是
不能识别class。
6. 然后又又写个小程序C来测试。程序C中的classes都属于default的package。在程序

一般的普通的class,可以通过MyClass.class得到,但是如果有Generics的情况,由于
type erasure,就没法得到它的class,比如我想用List.class,就会报错,
但是有些class method只接受这样的input argument:
public void foo(Class class)
如果我想传入一个List的类的话,怎么办?没法用
foo(List.class)

来自主题: _Climbing版 - Class System
The Class System (Sierra Club System and Yosemite Decimal System) describes
hike and rock climbing difficulty. The Sierra Club System describes hikes
of Class 1 through 4, and the YDS adds Class 5 and 6 to describe rock climbs.
Class 1: Hiking on trail
Class 2: Hiking off trail
Class 3: Scrambling. Will require the use of hands, typically for balance.
Class 4: Basic rock climbing. Will require the use of hands for balance and
forward movement. Beginners will want a rope belay.

Here's how much you have to earn to be considered upper class
http://www.msn.com/en-us/money/personalfinance/heres-how-much-you-have-to-earn-to-be-considered-upper-class/ar-BBysfNB?ocid=spartanntp
The research group found that "nationwide, the median income of U.S.
households in 2014 stood at 8% less than in 1999, a reminder that the
economy has yet to fully recover from the effects of the Great Recession of
2007-2009."
Despite this drop in income, members of the upper class are still doing well... 阅读全帖

2015款的奔驰C-Class (W205) 是一款操控不如Accord、空间不如Accord、可靠性不如
Accord、保值度不如Accord的样子货。
怎么说呢。。。大家都知道,比CRV轻了整整300镑的 2015奔驰gla-class (X156) 是公
认的一辆综合评价连Fit都不如的基于A-Class的拉皮mini station wagon,不论是操控
还是空间还是安全性都是同级别最烂,更不用说可靠性和保值度了。。。
然后呢,这2015款的C-Class竟然比gla这拉皮的A-Class还要轻、还要偷工减料:

来自主题: JobHunting版 - 问一个c++ virtual base class的问题
If you inherit a base class as virtual, only one subobject of that class
will ever appear as a base class. 下面这个例子:
#include
#include
using namespace std;
class MBase {
public:
int i_base;
virtual char* vf() const = 0;
virtual ~MBase() {}
};
class D1 : virtual public MBase {
public:
char* vf() const { return "D1"; }
};
class D2 : virtual public MBase {
public:
char* vf() const { return "D2"; }
};
// MUST explicitly disambiguate vf():
class MI : public D1, public D2 {

There was a news story this week that saddened me as I read it. Gary Neville
is retiring from playing soccer at the age of 35. Gary Neville, although
not one of the most technically gifted players in the world, was still one
of the best, if not the best full back over the last 20 years for both
Manchester United and England . What he lacked in skill, he made up for it
with commitment, passion and a love of the game. Probably the biggest thing
