Retrieve cell based on shortest distance

[sivalearn12]

Hi,
i need to create the cell for list of lat and long and then have to retrieve the cells based on shortest distance or nearby cells.

List S2CellList = new ArrayList();
S2Cell s2cell = new S2Cell(S2LatLng.fromDegrees(lat,long).toPoint());
S2CellList.add(s2cell);

like that i have added the set of cell to list for the list of lat and long. Now i need to show the cell with shortest distance. please guide me in coding.
