List<String> tokens = Arrays.stream("((!A1)&amp;(B2|C3))".split("((?<=[!&()|])|(?=[!&()|]))"))
                          .filter(token -> !token.trim().isEmpty())
                          .collect(Collectors.toList());

你可以使用以下正则表达式来匹配你想要的，而不是使用分割：
[!&()]|[^!&()\h]+
正则表达式详情：
- `[!&()]`: 匹配 `!` 或 `&` 或 `(` 或 `)`
- `|`: 或
- `[^!&()\h]+`: 匹配除了 `!`、`&`、`(`、`)` 和空白字符之外的任何字符
代码：
```java
final String regex = "[!&()]|[^!&()\\h]+";
final String string = "((!A1)&( B2 | C3 ))";
final Pattern pattern = Pattern.compile(regex);
final Matcher matcher = pattern.matcher(string);
List<String> result = new ArrayList<>();
while (matcher.find()) {
    result.add(matcher.group(0));
}
System.out.println(result);

Instead of split you can use this this regex to match what you want:
    [!&amp;()]|[^!&amp;()\h]+
[RegEx Demo][1]
  [1]: http://[!&amp;()]%7C[%5E!&amp;()%5Ch]+
**RegEx Details:**
- `[!&amp;()]`: Match `!` or `&amp;` or `(` or `)`
- `|`: OR
- `[^!&amp;()\h]+`: Match any characters that is NOT `!`, `&amp;`, `(`, `)` and a whitespace
**Code:**
    final String regex = &quot;[!&amp;()]|[^!&amp;()\\h]+&quot;;
    final String string = &quot;((!A1)&amp;( B2 | C3 ))&quot;;
    
    final Pattern pattern = Pattern.compile(regex);
    final Matcher matcher = pattern.matcher(string);
    
    List&lt;String&gt; result = new ArrayList&lt;&gt;();
    while (matcher.find()) {
        result.add(matcher.group(0));
    }
    System.out.println(result);
