Question

Write a program that will convert measurements expressed in inches,feet, yards, or miles
   into each of the possible units of measure. Themeasurement is input by the user, followed by
   the unit of measure. For example: "17feet", "1 inch","2.73 mi". Abbreviations in, ft, yd,
   and mi are accepted. The program will continue to readand convert measurements until the
   user enters an input of 0.

please rate - thanks import java.util.*; public class untitled { public static void main(String []args) {int num; double i=0,m=0,f=0,y=0; String measure; boolean error; char c; Scanner in=new Scanner (System.in); System.out.println("Enter a measurement: "); num=in.nextInt(); while(num>0)     {error=false;       measure=in.next();       c=measure.charAt(0);      switch(c)          {case 'f':f=num;                   i=num*12.;                   m=num*.000189393939;                       y=num/3.;                       break;            case'i':f=num/12.;                   m=num*1.57828283e-5;                       y=num/36.;                       i=num;                       break;            case'm':i=num*63360.;                   f=num*5280.;                       y=num*1760.;                       m=num;                       break;            case'y':i=num*36.;                   m=num*.000568181818;                       f=num*3.;                       y=num;                       break;            default:System.out.println("invalid measurement");                    error=true;            }       if(!error)         {System.out.println("inches= "+i);          System.out.println("feet= "+f);          System.out.println("yards= "+y);          System.out.println("miles= "+m);          System.out.println();           }              System.out.println("Enter a measurement:");      num=in.nextInt();      } } }
