Подскажите что не так!

if (charSymbolsFromFile == ' '){
  space++;
} else {
  symbols++;
}

space/symbols *100

double result = Math.round(((space+symbols)/space) *100);

while (fileReader.ready()){
                char charSymbolsFromFile = (char) fileReader.read();
                if (charSymbolsFromFile == ' '){
                    symbols++;
                    System.out.println(symbols+" sym");
                } else {
                    space++;
                    System.out.println(space+" space");
                }
            }
