编程实现 定义图形类,利用方法的重载,实现计算圆的面积,长方形的面积的方法定义

#includeusingnamespacestd;voidmain(){inta,b,c;intt;couta>>b>>c;if(a>b){t=a;a=b;b=t;}if(a>c){t=a;a=c;

importjava.awt.FlowLayout;importjava.awt.GridLayout;importjava.awt.event.ActionEvent;importjava.awt.

1.定义抽象类AbstractImageimportjava.awt.Graphics;publicabstractclassAbstractImage{publicabstractvoiddraw(

classRecangle{private:intwidth;intlength;public:Recangle(){width=0;length=0;};Recangle(intw,inth){wi

classfs{publicdoublea;//实部publicdoubleb;//虚部//加法publicfsadd(fsfs1){fsfs_temp=newfs();fs_temp.a=this.

类似的问题,在知道里面不知道有多少.搜索一下.

这个是三角圆和矩形的,你参考下,可以计算面积和周长publicclassHHsa{publicstaticvoidmain(String[]args){Geometricg=newTriangle(3

用什么语言编?

百度一下BCWHY去哪里提问吧.知道这里没人回答了.

classDate{intyear;intmonth;intdate;publicDate(intyear,intmonth,intdate){this.month=month;this.year=y

1.如果其直接子类不是抽象(abstract)的,那必须被重写2.如果其直接子类是抽象(abstract)的,那可以不被重写,由孙子类来实现3.至于孙子类要不要重写,遵循上述两条再问：重写就是over

难道也是东华的?
