biggest difference:

purpose of class is to represent objects
while
purpose of interface isn't to represent objects.....by
interface programmer gets only method names..but body is 2b
given by him....
now a question arises in my mind...if i'm giving body of
method then why shouln't i giv name too.....hmmmm.....

bete...interface ke methods ke body to programmer deta hai
bt chalata koi aur hai...it is not programmer who calls
these methods..


chinta mat karo...i'm giving example.....
EVENT HANDLING :ActionListener ko implement kiya,
actionPerformed() ki body di....magar actionPerformed() ko
humne nahi chalaya..note it
