Which Java execution environment is used by Sololearn?

Question

I'm not sure which JRE I should choose in Eclipse to create a new project.

Answer 1

JRE.
Actually I'm using 1.6 but while practicing nested-if-else my own written code did not work. In the end I copied to code out of the Code playground ~ and got the same unidentified error. So I thought it's maybe the wrong 'Patch'.
