Matcher 一个Matcher对象是一个状况机器,它根据Pattern对象做为匹配模式对字符串展开匹配检讨。 (2) Pattern的方法如下: static Pattern compile(String regex) 将给定的正则表达式编译并赋予给Pattern类 Matcher方式如下: int end() 返回当前匹配的子串的最后一个字符在原目标字符串中的索引地位。 boolean find() 尝...
字符串对象可以调用public String replaceAll(String regex, String replacement)方法返回一个字符串,该字符串是将当前字符串和参数regex指定的正则表达式匹配的子字符串用参数replacement指定的字符串替换后的字符串。(注意点:replaceAll()方法返回一个新字符串,不会改变当前字符串。) //例子一 String result = ...
