英文:
Regex to add square brackets into beginning/end sentence and also each word separate by comma?
问题
我需要使用什么样的正则表达式来在句子开头/结尾添加方括号，并且用逗号分隔每个单词？
我有一个像这样的句子：
qqqqqqq\
asadsds\
dsdadad\
sadadad\
asdsada\
dsadadd";
我期望得到如下结果：
[qqqqqq, asadsds, dsdadad, sadadad, asdsada, dsadadd]
我尝试了很多方法，比如：
String regex1 = "(^[a-zA-z_0-9])(\\s)([a-zA-z_0-9]$)";
英文:
What kind of regex do I need to use to add square brackets into beginning/end sentence and also each word separate by comma?
I have a sentence like this:
qqqqqqq\
asadsds\
dsdadad\
sadadad\
asdsada\
dsadadd";
I expecting to get result like this:
[qqqqqq, asadsds, dsdadad, sadadad, asdsada, dsadadd]
I try many things such as:
String regex1 = "(^[a-zA-z_0-9])(\\s)([a-zA-z_0-9]$)";

似乎您需要将输入字符串拆分成一些“单词”，因此需要使用 `String.split("\\W+")` 或 `String.split("[^a-zA-Z]+")` 来排除所有非字母字符或非单词字符作为分隔符。
然后，使用逗号重新连接清理后的单词，并添加括号，这可以通过 `Arrays.toString` 方法提供。
这可以简单实现如下：
```java
String input = "qqqqqqq\\\nasadsds\\\ndsdadad\\\nsadadad\\\nasdsada\\\ndsadadd\";";
System.out.println(input);
System.out.println("------------");
String result = Arrays.toString(input.split("\\W+"));
System.out.println(result);
输出：
qqqqqqq\
asadsds\
dsdadad\
sadadad\
asdsada\
dsadadd";
------------
[qqqqqqq, asadsds, dsdadad, sadadad, asdsada, dsadadd]
英文:
It seems that you need to split the input string into some "words" thus excluding all non-letter or non-word characters as delimiters using String.split("\\W+") or String.split("[^a-zA-Z]+").
Then re-join the cleaned words using commas and adding brackets which can be provided by Arrays.toString method.
This can be implemented simply:
String input = "qqqqqqq\\\nasadsds\\\ndsdadad\\\nsadadad\\\nasdsada\\\ndsadadd\";";
System.out.println(input);
System.out.println("------------");
String result = Arrays.toString(input.split("\\W+"));
System.out.println(result);
Output:
qqqqqqq\
asadsds\
dsdadad\
sadadad\
asdsada\
dsadadd";
------------
[qqqqqqq, asadsds, dsdadad, sadadad, asdsada, dsadadd]
