Answer Posted / james rajesh

One database tale contain id and name...mostly id's are in int and name's are in String...if u want to compare with id and one number means u use ==
like, if(id==1)
if u want to compare name means u use .equals
like, if(name.equals("Bangalore"))
So point of view,
== used to compare integer
.equals used to compare String
