用jAvA 正则表达式 提取IP地址

String reg = ".*\\/\\/([^\\/\\:]*).*";String str1 = "http://192.168.1.6:9999/caservice/webservice/caServiceWs?wsdl ";System.out.println (str1.replaceAll (reg, "$1"));String str2 = "http://192.168.1.6/caservice/webservice/caServ...

ip的正则表达式网上很多,比如:((2[0-4]\d|25[0-5]|[01]?\d\d?)\.){3}(2[0-4]\d|25[0-5]|[01]?\d\d?) 找文本中匹配的字符串好像Scanner有几个find***方法,但是我看不懂文档中对他们的解释 过滤重复可以使用set来存储这些ip,一样的就不会被重...

用正则表达式提取网址的方式如下: 用ifconfig来提取 ifconfig eth0|grep "inet addr"|awk '{print $2}'|awk -F: '{print $2}'192.168.10.1 用ip addr来提龋 ip addr | grep -Po '[^ ]+(?=/\d)'

你直接用matchs判断就可以了,matcher是只要内部有能匹配上的就算满足,不是判断整体。 String rexp = "([1-9]|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])(\\.(\\d|[1-9]\\d|1\\d{2}|2[0-4]\\d|25[0-5])){3}";String addr = "11111.1.1.1";System.out...

String regex="//(.*?):(.*)"; Pattern p=Pattern.compile(regex); String t="://127.0.0.1:8080"; Matcher m=p.matcher(t); while(m.find()){ System.out.println(m.group(1)); System.out.println(m.group(2)); }

package com;public class Joey{public static void main(String[] args){String ip = "10.1.107.0/24";String reg = "^((2[0-4]\\d|25[0-5]|[01]?\\d\\d?)\\.){3}(2[0-4]\\d|25[0-5]|[01]?\\d\\d?)/\\d+$";System.out.println(ip.matches(reg));}}

private boolean getALlAdress(String email){ String msg = null; Pattern p = Pattern.compile("\\w+@(\\w+.)+[a-z]{2,3}"); Matcher m = p.matcher(email); while (m.find()) { msg =matcher.group(); System.out.println(msg); } }

正则表达式匹配ip地址,实际上就是分别判断每个点直接的数字是否符合规范。 package com; import java.util.regex.Matcher; import java.util.regex.Pattern; public class TestRegex { public static boolean isboolIP(String ipAddress){ Stri...

IP地址:(2[0-4]\d|25[0-5]|[01]\d\d|\d\d|\d)\.(2[0-4]\d|25[0-5]|[01]\d\d|\d\d|\d)\.(2[0-4]\d|25[0-5]|[01]\d\d|\d\d|\d)\.(2[0-4]\d|25[0-5]|[01]\d\d|\d\d|\d) 邮件地址:[a-zA-Z0-9._%+-]+@(?!.*\.\..*)[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}

java用正则表达式统计ip个数: display ip count rule [ | { begin | exclude | include } regular-expression ] 参数说明: |:使用正则表达式对显示信息进行过滤。有关正则表达式的详细介绍,请参见“入门配置指导”中的“CLI”。 begin:从包含指...
