Macintosh OS/MacBook Air not responding


I recently upgraded to Yosemite. Now my iTunes will not open although it appears to be loaded. In trying to  get iTunes to respond I down loaded Java from Oracle to no avail However it has corrupted my start up with a warning that keeps responding each time I restart. Tried all kinds of thingsto no avail. Any hope for this old man and machine/
