Java 7 and 8 on the same PC?

Hi, just a quick question that I couldn't find a clear answer for on google...

Can I install java 8 without removing java 7, and be able to run programs by specifying which version to use?

 

So one program will be using  C:\Program Files\Java\jre7\java.exe

And another program will be running  C:\Program Files\Java\jre8\java.exe

 

Is this possible? Thanks :)

 

I want to upgrade to java 8 to run Minecraft, but I think the modded crackpack server I run needs to use java 7...

Ok I tried it and it worked.

For anyone trying to do the same thing, instead of running the server by 'java' in the batch startup file (which will not work when java 8 is installed) you need to do "C:\Program Files\Java\jre7\java.exe" and the server will use java 7 :)

I have java 7 and 8 both installed. You can prevent having to put the exact path by specifying your JAVA_HOME variable to point to java 7. Not hard thing to do. My eclipse environment for java development has like five versions of java available to me. 32 and 64 bit variations. Various updates to different editions. Some need removed lol
