I would suggest using regular expressions to find an ip address and the port. Here is a regular expression that is needed: java regex matching ip address and port number as captured groups This article explains how to use regular expressions in java: http://www.mkyong.com/regular-expressions/how-to-validate-ip-address-with-regular-expression/

thanks allot i am using regex pattern "\\d{1,3}(?:\\.\\d{1,3}){3}(?::\\d{1,5})?"; which works fine if the proxy and port are seperated by : but if they are seperaated by a tab space then i tought "\\d{1,3}(?:\\.\\d{1,3}){3}(\\s\\s\\s\\s\\s\\s\\s\\d{1,5})?"; but i only outputs the proxy not the port any suggestions would be great as untill last night i didint even know of this java function thanks – user2155009 Mar 11 '13 at 14:50
There is the sequence "\\t" for a tab space. – alu Mar 11 '13 at 17:23
