Java is used quite often in the business industry. You can't argue for a coin's success or failure based on the programming platform, especially when Java and C++ are concerned.
Can you give some examples of how Java is used in the business industry?
Oracle, SAP, a bunch of IBM stuff on OS/390 and AS400... but they surely just peasants in great poverty (unlike OP) so you can safely ignore them
. Ooops... I've forgot Cisco, HP and Google. Sorry for that
