步骤4: 使用Matcher进行匹配 使用Matcher对象的find()方法进行匹配,这个方法将查找第一个符合条件的字符串。 代码解读 // 使用Matcher查找符合条件的字符串if(matcher.find()){// 如果找到了,打印匹配的字符串StringmatchedString=matcher.group();// 获取匹配的字符串System.out.println("匹配到的字符串是: "+ma...

Matcher(String) Creates a matcher that will match the given input against this pattern. C# publicJava.Util.Regex.MatcherMatcher(stringinput); Parameters input String The character sequence to be matched Returns Matcher A new matcher for this pattern ...

这样可以通过matcher.group(groupName)得到具体匹配的group是谁,这样便于后续分析,否则不好分析。 错误 java.lang.IllegalArgumentException: No group with name <>at java.util.regex.Matcher.getMatchedGroupIndex(Matcher.java:1316) at java.util.regex.Matcher.group(Matcher.java:572) ...
