JAVA 正则表达式 : Making custom regex for String. split()

Question

我需要以仅忽略这些标点符号的方式分割字符串:

(.)、(,)、(!) 和 (?)

所以如果我有这个字符串:

String a = "I can't split this string! Guys, can you help me? Thanks in advance."

我有这个正则表达式(它没有帮助):

String.split("[\\p{Punct}\\s]+");

它的输出是:

IcantsplitthisstringGuyscanyouhelpmeThanksinadvance

如果您注意到 can't 被拆分，因为撇号是作为标点符号给出的，而我不想这样。

Answer 1

  public static void main(String[] args)
  {
    String a = "I can't split this string! Guys, can you help me? Thanks in advance.";

    String[] splitted = a.split("[.,!?\\s]+");
    for (String s : splitted)
    {
      System.out.println(s);
    }
  }

如果您不想用空格分隔，请删除 \\s
