我想找到给定字符串
中最长的单词。
以下代码检查最长的单词,但我希望所有其他单词也具有相同的长度。
try (BufferedReader fileInputReader = new BufferedReader(new FileReader(filePath))){
String line = fileInputReader.readLine();
line = line.replaceAll("[^äÄöÖüÜßa-zA-Z ]", "");
String[] sentence = line.split(" ");
String longestWord = "";
for (int i = 0; i < sentence.length; i++) {
if (sentence[i].length() > longestWord.length()) {
longestWord = sentence[i];
}
}
System.out.println(longestWord);
}
最佳答案
然后您必须使用这些最长单词
的集合,例如
ArrayList<String> longestWords = new ArrayList<String>();
int longestWordLength = 0;
for (int i = 0; i < sentence.length; i++) {
if (sentence[i].length() > longestWordLength) { // longer
longestWordLength = sentence[i].length();
longestWords.clear();
longestWords.add(sentence[i]);
}
else if (sentence[i].length() == longestWordLength) { // same length
longestWords.add(sentence[i]);
}
}
for (int i = 0; i < longestWords.size(); ++i)
System.out.println(longestWords.get(i));
