Pattern类只能做一些简单的匹配操作,要想得到更强更便捷的正则匹配操作,那就需要将Pattern与Matcher一起合作.Matcher类提供了对正则表达式的分组支持,以及对正则表达式的多次匹配支持. Java代码示例: Pattern p=Pattern.compile("\\d+"); Matcher m=p.matcher("22bb23"); m.pattern();//返回p 也就是返回该Mat...
Java bytecode compiler. The string literal"\b", for example, matches a single backspace character when interpreted as a regular expression, while"\\b"matches a word boundary. The string literal"\(hello\)"is illegal and leads to a compile-time error; in order to match the string(hello)...
