Plotting some POIs on a graph/map
Part 1: Several kinds of point of interests (POI) like:
(A) Petrol station,
(B) Taxi Stand,
(D) Hospital and
(E) Shopping centre is located in a city.
Their locations (that is, longitude and latitude) are given in a text file (a file will be given in the resource section of the subject site or you can make your own dummy text file according to the format you prefer). You should work with at least one type or kind of POI and at least 20 samples (illustration: your text file must contain the location of 20 petrol stations in a city). You have to prepare a JAVA program which would get the locations of all the POIs from the file and plot them on a map (or graph). Optional: Save the map or graph in a file if the user wants to.
Part 2: Incorporate a method to zoom in/out the map either by having buttons or with the aid of the scroll button.
