hi, why my code when i try to calculate BMI every time the answer equal 0.0 and can't get the right answer? package a; import java.util.*; public class a { public static void main(String []args){ Scanner sc=new Scanner(System.in); label: System.out.println("Enter the number of cities"); int noOfcities,nPerson; noOfcities=sc.nextInt(); int under=0,obese=0,normal=0,over=0,c_under=0,c_obese=0,c_normal=0,c_over=0; double p_under,p_over,p_obese,p_normal; double max_normal=0.0,max_obese=0.0,min_under=100.0; String name,b_city="None",w_city="None",u_city="None",cat; int mass,height; while ( noOfcities<6){ System.out.println("erro"); System.out.println("Enter the number of cities"); noOfcities=sc.nextInt(); }int i=0; while (i=10) for(int j=0;j=18.5 && bmi<25) { cat="normal"; c_normal++; } else if(bmi>=25 && bmi<30) { cat="overweight"; c_over++; } else { cat="obese"; c_obese++; } System.out.println("The person has a BMI of "+bmi+" and belongs to category "+cat); } under+=c_under; over+=c_over; normal+=c_normal; obese+=c_obese; p_under=(under/nPerson)*100; p_normal=(normal/nPerson)*100; p_over=(over/nPerson)*100; p_obese=(obese/nPerson)*100; System.out.println("For the city "+name+" category wise breakup is:"); System.out.println("Number of people who are Underweight: "+under+ ", Percentage is: "+p_under); System.out.println("Number of people who are Normal: "+normal+ ", Percentage is: "+p_normal); System.out.println("Number of people who are Overweight: "+over+ ", Percentage is: "+p_over); System.out.println("Number of people who are Obese: "+obese+ ", Percentage is: "+p_obese); if(p_normal>max_normal) { max_normal=p_normal; b_city=name; } if(p_obese>max_obese) { max_obese=p_obese; w_city=name; } if(p_under
