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。 // 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: "+matchedString...
6. 使用group()方法获取匹配到的字符串 如果在上一步中找到了匹配项,我们可以使用Matcher对象的group()方法来获取匹配到的字符串。 下面是使用group()方法获取匹配到的字符串的代码示例: StringmatchedString=matcher.group(); 1. 在上述代码中,我们使用Matcher对象的group()方法来获取匹配到的字符串,并将其赋值给...
Pattern pattern = Pattern.compile("\\d+"); String text = "12345abc67890"; Matcher matcher = pattern.matcher(text); while (matcher.find()) { System.out.println("The matched substring is: " + matcher.group()); } // 程序输出: The matched substring is: 12345 The matched substring is: ...

// The matched text can be obtained using m.group() or m.group(0)String phone = m.group();String areaCode = m.group(1);System.out.println("Phone: " + phone + ", Area Code: " + areaCode);} } } 2、在正则表达式中使用命名组 import java.util.regex.Matcher;import java.util....

This class also defines methods for replacing matched subsequences with new strings whose contents can, if desired, be computed from the match result. The#appendReplacement appendReplacementand#appendTail appendTailmethods can be used in tandem in order to collect the result into an existing string bu...
