What exactly is "N" encryption? 802.11n is a standard for implementing wireless local area network computer communication, know commercially as Wi-Fi since 1999. Wi-Fi has three security methods. WEP, broken easily years ago, WPA and WPA2. Both WPA methods have vulnerabilities. The only way to secure WPA is to turn off Wi-Fi Protected Setup.
Also JAVA is far from the biggest security risk. That would be Flash, simply because far more computers have it installed and far more websites use it.
