Installing Java + ABAP trial version

Hello All,

I installed ABAP trial version ( SAP NetWeaver 7.0 - ABAP Trial ) on my laptop...I want to install JAVA as well...is there a way for me to keep both languages...I mean if I want to create a program in ABAP...I can open the ABAP editor and code in ABAP...and if I want to code in JAVA...I can open the JAVA editor and run the JAVA program...

Is there a way to do that? Or I need to uninstall the ABAP trial version first and than install JAVA trial version (SAP NetWeaver 7.0 - Java Trial )...

Secondly I also want to learn BI? What I need to install in ABAP trial version to get access to BI?

Thanks...

Appreciate all the help in advance...
