 public static void main (String arg[]) {
  Scanner in=new Scanner (System.in);
  int a;

  System.out.print ("\n\t Enter the temprature in Celcious = ");
  a=in.nextInt();

  if (a<=20)
   System.out.print ("\n\t Whether is Cool ");
  else if (a<=30 && a>=21)
   System.out.println ("\n\t Whether is Fine ");
  else if (a<=40 && a>=31)
   System.out.println ("\n\t Whether is Hot ");
  else
