java - split 方法中使用多个正则表达式

Question

如果在我的字符串中两个正则表达式是连续的 [逗号(,) 和空格()]，所以我想处理一个正则表达式，那么我该怎么办。

String s = "He is a very very good boy, isn't he?";
String str[]=s.split("[!._,'@? ]");

我的输出是:-

11
He
is
a
very
very
good
boy
space( )
isn
t
he

我想要这个:-

10
He
is
a
very
very
good
boy
isn
t
he

在拆分中使用两个标记，只需将 + 添加到您的模式中以指示它应该匹配一个或多个；就像，

String[] str = s.split("[!._,'@? ]+");
