generally for every object contains one unique hashcode generated by jvm. \
hashcode tells the programmer which class object it is. \
\
OBJECT class produces one unique code for object. i.e, hexa decimal integer. \
\
if u dont like this hexa decimal numerical value there is a chance to overridde hashcode value and whatever value give for that object then u should override hashCode() method in ur class and return it.

if u want to check object's content then you have to override equal() and hashcode(). basically hashcode() is check reference address only
