［发泄帖不喜勿进］100刀就这么被花掉了阿
我核算了一下，INTERNATIONAL STUDENT的总学费除以总学时，基本上结果是上一个小时课=花掉100刀……PS 100刀这边能干什么？能让你吃大约20次M记，买几件MADE IN CHINA的衣服，交付1间小房间1周的房租，或者打车去很远的地方玩。
好吧，正题，今天上课老师让学习如何用JAVA画图，然后给个半成品让我们补充完整，结果发现该有的都没有，还得从头学Graphic，结果1小时光看参考资料了，总算明白人家写的都是什么了，课也下了……
结果去骨骼上一搜HOW TO DRAW A CIRCLE USING JAVA，马上找到了最简单解决方案：用JAVA APPLET，完整程序我5分钟就全弄出来了。
这学校真不厚道，明明可以用简单易懂的方式去处理问题，非要绕圈子，我花钱上学也不是让你这么干的阿？愤怒！
import java.awt.*;
import java.applet.*;
public class HouseshapeDrawing extends Applet
{
public void paint(Graphics g)
{int xCoords[] = {125,100,150};
int yCoords[] = {10,60,60};
Polygon triangle = new Polygon(xCoords, yCoords, 3);
g.fillRect(100,60,50,50);
g.fillOval(120,0,10,10);
g.fillPolygon(triangle);
}
} - -JAVA的基础,MS我最开始看那本书第二节就开始讲这个..... 我连C语言都苦手，JAVA就更是浮云了.....OTZ 自己动手丰衣足食，我们想拿平时成绩满的人都是老师没交就开始K书开始做ASSIGNMENT了，等老师全部讲完开始做的人基本都会死掉。所以我很怀疑要老师讲起多大作用，直接把参考书全A完估计也就修炼圆满了。关键这边老师还基本不答疑问，每周找个人问问题MB还要电话/EMAIL预约…… 青蛙~很多基础都是要学的，高数也是要4则运算为基础的呀 原帖由 中中 于 2007-3-13 11:34 发表 http://bbs.newwise.com/images/common/back.gif

关键他给的那个STUB不是基础，是从复杂程序中拿出一块让你用的，具体说也不清楚，反正不符合我直接设计的思路，绕圈子好多阿。
不正学APPLET基础么，我就不信我另起炉灶还做不出来了。
PS.我们老师写的程序，让你用这个套，我看半天还是没干出来，怒了直接换APPLET。
中哥是强人俺是知道的，赶明我的小组ASSIGNMENT还可以问你=口=V

我那都是衣食住行的基本需求，你这都是奢侈消费，人跟人咋就这么不一样一一？
BS阿BS -_- 我也是衣食住行阿 你BS我 我还BS你花美刀呢
那100刀可以两个人去威斯汀吃自助
可以买件春装衬衫 还多点钱
可以开个两个人的最便宜的温泉房
可以坐打折飞机票来回上海北京 吉娜,你还学java?偶记得你不是读的那个啥么... 青蛙你到底是学啥的- -不是文科么 很清楚的记得青蛙是文科呀 事实是,你们都被骗了- - 谁告诉你们我学文科的，顺便，JAVA已经学过一个学期了，也算入门了吧，现在只要能利用网络材料基本能照猫画虎，正在做大作业，设计超市出纳系统……
在中国光学C++了没JAVA什么事。 我一年48学时，要16000刀，我也想放火烧学校啊~~~~~~ 牛以前不是专做商场专柜的收钱系统的么 原帖由 在风中中风 于 2007-3-13 15:36 发表 http://bbs.newwise.com/images/common/back.gif

学分吧？一年才上48个小时的话，你学校老早就被别人烧掉了~ 原帖由 xliz 于 2007-3-13 14:34 发表 http://bbs.newwise.com/images/common/back.gif

啊，口误，作为穷人希望今年申请奖学金能成功，买个PS3，然后当场砸掉。 LZ要想到我的头像等先辈，那时候他们只有更苦 kao 我30学时只收3200RMB！来跟我学吧
