Java按空格，新行，制表符，标点符号拆分字符串

Question

大家。

我有这样的字符串

String message = "This is the new message or something like that, OK";

我想把它拆分成数组

String[] dic = {"this", "is", "the", "new", "message", "or", "something", "like", "that", "OK"};

我用了

message = message.split("\\s+");

问题在于它包含“那个”，而不是“我想要的”。 请教我如何解决它。 谢谢

Answer 1

你可以做

String[] dic = message.split("\\W+");

\\\\W表示不是字母数字字符。

Answer 2

您可以使用StringTokenizer

 String message = "This is the new message or something like that, OK";
 String delim = " \n\r\t,.;"; //insert here all delimitators
 StringTokenizer st = new StringTokenizer(message,delim);
 while (st.hasMoreTokens()) {
     System.out.println(st.nextToken());
 }

Answer 3

使用番石榴 ：

// define splitter as a constant
private static final Splitter SPLITTER =
Splitter.on(CharMatcher.WHITESPACE.or(CharMatcher.is(','))
        .trimResults()
        .omitEmptyStrings();
// ...

// and now use it in your code
String[] str = Iterables.toArray(SPLITTER.split(yourString), String.class);
