After much research, I still have difficulties with java, I'm new and I'm trying to learn. Please excuse me if I can not ask a clear question, because I may not even know what I'm talking about,
BOM, for example the part of maps that I can already open, but with an "example" position
and for this I am using the following code:

How can I open this map already in my location? I happen to get lots of examples on Google, but I just can not do anything to fit it ...
Thanks for the help and goodwill !!
