The program must have three classes. A main class, circle class and a rectangular class.

Scanner nScan = new Scanner(System. in);
DecimalFormat mf = new DeciamlFormat("0.0");
Circle cir1 = new Circle(0,0);
Rectangle rec1 = new Rectangle (0,0,0);

//variables
boolean runProg = true;
int choice =0;

while(runProg)

System. out. print("Math calculator 3000 ver1");
System. out. print("choose a mode. \n"
+ "1 circle mode \n"
+ "2 Rectangle mode \n"
+ "3 End program");
choice = nScan. nextInt();

if(choice==1) //circle mode
{

}

else if(choice == 2) //Rectangle Mode
