Map is a collection of key value pairs. But List is a collection of elements. To convert it to a map u have to attach a unique key(or value) to each element in the list, so that it acts as map. In that case just iterate thru and for each element add a key to it( or value)

I hope thats clear

HI,
map stores data in key/value pairs. But list is having only objects.
so one thing what u can do is, as a key element u can store Integer object, and as a value u can store list objects. But otherwise it is not possible.
any comments!!

Hi Parameswaran,
U need to store Key/ value pairs into Map right.
Any way we are going to store List objects as Value, we need to store some object into the map as a Key. So it will be easy if we canb store Integers as Keys. We cant store integer primitive data type here, so i said integer objects.
i think u got my point.
