Hi Keshari,
maybe it is easier if you will have a look to this configuration video:

Your stuff will be explained in video 4: https://scn.sap.com/docs/DOC-40322
I hope this helps.
In general, you need to configure SPN with the hostname, the users will access this AS Java system.
So if the users are using the URL HTTP://hostname.abcuniversity.net:8000the SPN entry should be HTTP/hostname.abcuniversity.net
Of course you can define more than one entry.
Best regards,
Frane
