java - Android(Java)代码中的正则表达式疑问

Question

谁能告诉我这个正则表达式到底在做什么？

new StringTokenizer(string,":/.@\\;,+ ");

我无法理解这个 Regex 的确切含义，尽管它看起来与根据特殊字符拆分字符串有关？

Answer 1

StringTokenizer 不使用正则表达式。第二个参数是用作标记之间分隔符的字符列表。

JavaDoc 说:

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.
