．编写一个完整的Java Application 程序。包含接口ShapeArea，MyRecta具体要求如下：
⑴接口ShapeArea：
getArea()：求一个形状的面积
getPerimeter ()：求一个形状的周长 ⑵类 MyRectangle：
实现ShapeArea接口，并有以下属性和方法： ① 属性 width：
double类型，表示矩形的长 height：
double类型，表示矩形的高 ② 方法 MyRectangle(double
h)：构造函数
toString()方法 ：输出矩形的描述信息，如“width=1.0,height=2.0, perimeter=6.0, area=2.0” ⑶类MyTriangle：
实现ShapeArea接口，并有以下属性和方法： ① 属性 x,y,z: double型，表示三角形的三条边 s: 周长的1/2（注：求三角形面积公式为 ，s=(x+y+z)/2 ，开方可用Math.sqrt(double)方法） ② 方法 MyTriangle(double
z)：构造函数，给三条边和s赋初值。 toString()：输出矩形的描述信息，如“three sides:3.0,4.0,5.0,perimeter=12.0,area=6.0” ⑷Test类作为主类要完成测试功能 ① 生成MyRectangle对象 ② 调用对象的toString方法，输出对象的描述信息
血刃迷茫t84
以下每一个类和每一个接口都各自存成一个和类名或接口名一致的文件，然后编译后运行Test类。

把楼上的优化一下：
#include "stdio.h"
#include "math.h"
void main()
{ int i,j,k;
...
#include &iostream&
int i,input=0,count=0,sum=0;
很简单啊，直接一个for循环就可以啦。
#include&iostream&
int main()
要想自动加载，大约有这么几种方法：
1.用命令或者菜单预加载。命令appload（菜单[工具/tools]&&[自动加载应用程序/automatic load ...
要看你的机子的配置了，魔兽的要求挺高的。你下载是应该看清楚的。当然也应该打补丁的。
