I recommend a third party library. Antlr has a Java syntax already worked out. There's also other dedicated Java parsers. Note you're talking about two things here. Lexing and parsing. A lexer breaks text up into tokens, a parser decides how to interpret the result. Parsers traditionally have a lot more contextual information, whereas lexers are just simpler state machines that break up text.
