You force L2JFrozen to use 1.6, therefore you can't use new ArrayList<>(), you have to add the type of ArrayList into <>.

 

You can also edit -source 1.6 for -source 7 and use java 7. The best being using directly java 8.

Well, typically you would start by removing obsolete java installations. Java 6 and under is now deemed as critical security risk in both Oracle (incl. Open) and IBM JVMs (which together take up more than 90% of all JVM installations). If you have any project that uses java 6 or earlier, you should face the facts: it's not just dead. It's buried so deep down below, it would take a expert miner crew to recover anything useful out of it.

 

With that out of the way, eclipse can run itself on a JRE, so you can technically skip path and other env. setup and use the same old Window->Preferences->Java->Installed JREs method. As long as you know how to get to that dialog, everything else is self-explanatory. As it always was.

 

EDIT: Try has already specified the minimal Java version you will need. Just don't use Oracle/Open Java 7 JVM, it's a critical security risk. So if you want to stick with Oracle, you must go straight to Java 8. Which is a good choice in any case.
