Java word count program

Question

I am trying to make a program on word count which I have partially made and it is giving the correct result but the moment I enter space or more than one space in the string

Answer 1

public static int CountWords(String str){

   if(str.length() == 0)
          return 0;

   int count =0;
   for(int i=0;i< str.length();i++){


      if(str(i) == ' ')
          continue;

      if(i > 0 && str.charAt(i-1) == ' '){
        count++;
      } 

      else if(i==0 && str.charAt(i) != ' '){
       count++;
      }


   }
   return count;

}
