Question

Problem 5) Simplify the code for the following method as much as you can.(Java)

   public static int inTheInterval(int n)
   {
      if (n < 0)
         return -1;
      else if (0 <= n && n <= 1)
         return 0;
      else if (n > 1)
         return 1;
      return 42;  // we never get here
   }
