I'm trying to make a programm, wich gets a word from a website, wich always gives you a random (german) word and count how frequently a character is in the word. When I try my programm with a stream from a list it works fine. If I read from the website, the word is displayed fine with System.out, but counting the letters does not work as intended. Here is my code:
public class WordCount {
public static String charStat(String urlString) throws IOException {
/* List<String> list = new ArrayList<>();
list.add("word");
Stream<String> characterStream = list.stream();*/ //works totaly fine every time
URL url = new URL(urlString);
Stream<String> characterStream = new BufferedReader(new InputStreamReader(url.openStream())).lines();
BufferedReader br = new BufferedReader(new InputStreamReader(url.openStream()));
System.out.println(br.readLine());//BufferedReader only used to print the word so I can controll
//if everything is working
int[] charNumber = new int[26];//size is 26 cause the alphabet has 26 characters
Runnable func = () -> {
characterStream
.map(String::toLowerCase)
.flatMapToInt(CharSequence::chars)
.filter(c -> c != ' ')
.map(c -> c - (int) 'a')//subtracting 'a'(95 in ascii) so a is in position 0 of the array
.forEach(i -> {charNumber[i]++;});
};
func.run();
characterStream.close();
return "a: " + charNumber[0];//returning how many times the letter a is present, could be any letter
}
public static void main(String[] args) throws IOException {//Ik that main shouldn't throw an exception
System.out.println(charStat("https://randomeword.azurewebsites.net/api/word"));//the website im
//getting the word from
}
}
Example from a fail:
word:
Klavierkonzert
the array:
[1, 0, 0, 0, 3, 0, 2, 0, 1, 0, 0, 0, 0, 3, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 1]
the should be:
[1, 0, 0, 0, 2, 0, 0, 0, 1, 0, 2, 1, 0, 1, 1, 0, 0, 2, 0, 1, 0, 1, 0, 0, 0, 1]
I don't know why this is happening as the word gets shown correctly with System.out.println();. So if I've done anything wrong let me know.
