如何根据某些字符在Java中拆分字符串？

Question

我分裂了

String example = "That's called -- a cross-country vehicle!";

进入数组：

[That's, called, a, cross-country, vehicle]

使用String.split()？

到目前为止，我已尝试使用example.split(" "); 并使用for循环打印出来，我得到了：

That's, called, --, a, cross-country, vehicle!.

但是，我希望它忽略--和!。我想只打印出通过单词连接器连接的单词和单词。

Answer 1

你想分开一个空格或爆炸，加上可选的更多破折号和空格紧跟在下面：

example.split("[! ][- ]*");

请参阅live demo：

String example = "That's called -- a cross-country vehicle!";
String[] words = example.split("[! ][- ]*");
System.out.println(Arrays.toString(words));

输出：

[That's, called, a, cross-country, vehicle]
