Question

我解析一个txt文件，把所有行组合成一个string，然后怎么拿出里面所有的手机号码，求代码实现。
mobileCheck的正则表达式要怎么写
Pattern p = Pattern.compile(mobileCheck);
Matcher m = p.matcher(mobile); 接下去要怎么写呢

Answer 1

A very basic implementation, you can find the solution by searching online.

// A mobile phone number verification regular expression found online (may not be the latest)
String mobileCheck = "(0|86|17951)?(13[0-9]|15[012356789]|17[0678]| 18[0-9]|14[57])[0-9]{8}";

// It can probably be implemented as follows, reading the file and concatenating it into a string is not given

String mobileCheck = "(0|86|17951)?(13[0-9]|15[012356789]|17[0678]|18[0-9]|14[57])[0-9]{8}";
String txtContent = "QQ：456456；座机是：0532214；手机1：13678888888；邮箱是:abc123@abc.com；手机2：15056666666。";

Pattern p=Pattern.compile(mobileCheck); 
Matcher m=p.matcher(txtContent); 
while(m.find()) { 
     System.out.println(m.group()); 
}
