Find biggest 2 numbers

Hi friends,

Yesterday I have attended one interview , I got question like these,

3,4,5,67,1,67,233,466

How to find biggest of 2 numbers amoung these numbers .

Should not use any sorting algorithm
also they asked me to use any collection classes.
Also how to find duplicate of these numbers

Please any one help me to get solution for this.

Thanks

Kavitha, you got to read Collection API from Thinking In Java !!

hi,

in collection class,TreeSet class is there,which avoid dupulicatevalue and also it will arrage the datas in ascending order..so last number is greatest number,and prvious one is 2nd greatest number

note:which class implements set interface always has the above properties

thanks & regards,
