Class 28:

public static int countGreaterThanZero(int[][] list) {
   int count = 0;
   for (int i=0;i<list.length;i++)
      for (int j=0;j<list[i].length;j++)
         if (list[i][j] > 0)
             count++;
   return count;
}

1. public static int countChar(String s, char c) {
      int count = 0;
      for (int i=0;i<s.length();i++)
         if (s.charAt(i) == c)
            count++;
      return count;
   }
   

2. public static String removeQuotes(String s) {
      if ((s.length() == 1) && (s.charAt(0) == '"'))
         return "";
      if (s.length < 2)
         return s;
      if ((s.charAt(0) == '"') && (s.charAt(s.length()-1) == '"')
         return s.substring(1,s.length()-1);
      return s;
   }
