我真的很喜欢 ANTLR，尽管如果您只需要执行标记化，它可能会相当重量级 - 但如果您需要一个词法分析器/解析器，特别是在 Java 中。
I really like ANTLR, although it may be quite heavyweight if you only need to perform tokenisation - but it's great if you need a lexer/parser, particularly in Java.
虽然jdk里已经包含了，但是你有没有看过java .util.Scanner？我前段时间也用过JFlex，发现它相当不错。
Although it is included in the jdk, have you looked at java.util.Scanner? I have also used JFlex some time ago and found it quite good.
