我如何在代码Java中计算文件中每个段落的字数？

Question

你能帮我在这段代码中添加一个额外的检查吗？这个检查可以帮助我找出每一段的字数？

BufferedReader br=新的BufferedReader（新的InputStreamReader（新的FileInputStream（path）））；

String line = " ";
int countWord = 0;
int sentenceCount = 0;
int characterCount = 0;
int paragraphCount = 1;
int countNotLetter = 0;
int letterCount = 0;
int wordInParagraph = 0;

while ((line = br.readLine()) != null) {
    if (line.equals("")) {
       paragraphCount++;
    } else {
        characterCount += line.length();
        String[] wordList = line.split("\\s+");
        countWord += wordList.length;
        String[] sentenceList = line.split("[!?.:]+");
        sentenceCount += sentenceList.length;
        String[] letterList = line.split("[^a-zA-Z]+");
        countNotLetter += letterList.length;
    }

    letterCount = characterCount - countNotLetter;
}
br.close();
System.out.println("The amount of words are " + countWord);
System.out.println("The amount of sentences are " + sentenceCount);
System.out.println("The amount of paragraphs are " + paragraphCount);
System.out.println("The amount of letters are " + letterCount);

段落中的单词总数应该与所有行的单词总数wordcount相同。

如果必须计算每段的字数，那么wordsinParage应该是整数列表list wordsperParage ，可以这样计算：

int wordInParagraph = 0;
List<Integer> wordsPerParagraph = new ArrayList<>();

while ((line = br.readLine()) != null) {
    if (line.equals("")) {
       paragraphCount++;
       wordsPerParagraph.add(wordInParagraph);
       wordInParagraph = 0;
    } else {
        characterCount += line.length();
        String[] wordList = line.split("\\s+");
        countWord += wordList.length;
        wordInParagraph += wordList.length; // !!!

        String[] sentenceList = line.split("[!?.:]+");
        sentenceCount += sentenceList.length;
        String[] letterList = line.split("[^a-zA-Z]+");
        countNotLetter += letterList.length;
    }

    letterCount = characterCount - countNotLetter;
}
// in case the last paragraph does not have trailing empty line
if (wordInParagraph != 0) {
   wordsPerParagraph.add(wordInParagraph);
}
