在java中将特定的单词与字符串分开。

String sentence = "Hello world! This is a sentence.";
String[] words = sentence.split(" ");

String sentence = "Hello World! This is a sentence.";
Pattern pattern = Pattern.compile("\\b[A-Z]\\w*\\b");
Matcher matcher = pattern.matcher(sentence);
while (matcher.find()) {
    String word = matcher.group();
    System.out.println(word);
}
