Learn Java

I picked this Java course from Edureka http://www.edureka.co/java-course.  I'm now rethinking that decision.  My goal was to find a course that would give me a certification of some type quickly. The videos are good enough I suppose and the support is good, email is responsive.  Unfortunately, the course requires Eclipse which cannot be installed at work.  In fact, I had planned on using one of the websites below to resolve that issue but only the one at the top works well.

What I had hoped for initially is that I would be able to collaborate in real-time but that option appears limited.  Assistance in finding other options for getting through the course without Eclipse is greatly appreciated.

http://ideone.com - java and other high level stuff, sharing unclear 11-16-14  << most plausible option
http://www.tutorialspoint.com - java, web, and database tutorials, some components may be blocked, lots of example syntax 11-16-14
http://jsbin.com/#/cawucoqizo/1/edit - logged in via github, css, html, javascript, sharing unclear 11-16-14 << possible but javascript only
https://www.codebox.io/stack/java - signups through google, github, etc is diabled but reports to have sent a reset link to tedpenner@gmail.com 11-16-14
https://c9.io/ - login through github is nice, doesn't support ie but working on it 11-16-14
https://codeanywhere.com/ - let's you login, then nothing 11-16-14
