I need help on my Java program, the purpose of the program

Customer Question

I need help on my Java program, the purpose of the program is given n and the location of each store in terms of latitude and longitude, then report the closest pair of stores(in alphabetical order) and the distance between them to the nearest 0.1km. But
when I test the program with a very large number of n, It will promote a OutOfMemoryError: Java heap space, and I also keep getting a wrong answer from other test cases as well, I think there must be something wrong with my calculation of latitude and longitude.
I've been told that the latitude is unique in the range [-90,90] degrees but -180 and 180 longitude are the same, so I should think hard about which to map to which of the planar coordinates as in class, but I've no idea what is this exactly meaning, I am
assuming it have to do with the fact that if i have a point on the very left edge and one on the right edge then they could also be candidates. I've attached a small test case which is the sample input and output, and also a large test case which is the one
that cause a OutOfMemoryError to my program...Can anyone give me a help on this please ? Thank you
