jProxyChecker is a Proxy Checker written in java that can determine if a proxy is alive, where is located and the level of its anonimity. You can add\delete single proxy, imports a list from your hard drive\remote url and exports the scanned proxy.
WARNING
This code is not tested accurately. The main problems are related to: 1. The method that check if a proxy is alive. (funny for a proxy checker, i know) 2. The method that test the anon level is only theorical so don't give it too importance. (same fun as 1)
