关键代码：
for(int i=100;i>0;i=i-5)
Systemoutprint(i+"");
流程图就是：开始-》进入循环-》判断是否满足循环条件-》满足，继续并且打印-》不满足，跳出循环。画成图就行了，建议用visio画图，比较专业
前端是用Javascript *** 作canvas绘出各个元素（因此一些老的浏览器，如IE6、7等，无法使用），这些元素都是预定义的（包括rectangle,teardrop,standardImage等等），因此在浏览器中可以任意缩放而不失真。
保存到后端的时候将整个画布和元素的属性定义用json（具体格式可以看pos文件或者看POST的内容）传到服务器（应该是java实现的），重新绘制成PNG（他们的PDF就是PNG转的，所以无法矢量缩放）提供用户下载
我有源代码：绝对可以通过，不过比较简单而已，对学生而言应该可以了吧，这是以前写的：
一下两个文件放在一个包里就行了

Assignment number: #4
Description: In this program ,a frame will be created which contains
ten "mines"When you click a button ,it will present the
number of mines around or a message of losing the game
(if the button is a mine)You can make a right click to
sign a dengerous button as wellWhen all the mines have
been signed ,a message box of winning the game will jump
to the screenAnd the the message of the time you used in
the gameMore over,you can click the button on the bottom
to restart the game

switch好像不行，case后面要的是常量,
参考代码：
import javaio;
public class Demo{
public static void main(String []args){
try{
int score;
String inpt;
Systemoutprintln(" please input the score：");
BufferedReader br=new BufferedReader(new InputStreamReader(Systemin));
inpt=brreadLine();
score=IntegerparseInt(inpt);
if(100==score)
Systemoutprintln("father's promise:buy car");
else{
if(90<=score)
Systemoutprintln("mother's promise:buy computer");
else{
if(60<=score)
Systemoutprintln("mother's promise:buy phone");
else
Systemoutprintln("no gift");
}
}
}
catch(Exception e){
Systemoutprintln("invalid input!");
}
}
}
