Downloading a map image using Google Map using Java -

-

what want do:

i want create little program in java (beginner in java here) in specify gps location , zoom level , download map image google maps showing. associated this, need have scale associated image (the size in km of x , y dimensions of rectangular image).

what know:

i know how right image displayed in browser, specifying gps location , zoom level directly in url (example: https://maps.google.com/maps?f=q&hl=de&geocode=&q=48.167432,+10.533072&z=7). there should kind of library urllib in python call url.

how download image, , how know area pictured in it? found formula relate amount of meters (or whatever unit) "contained" in pixel (this function depends on latitude , zoom level of map). in case, how know pixels used map?

thank suggestion and/or pointer!

you want use static maps api.

https://developers.google.com/maps/documentation/staticmaps/index

your particular map @ url 

http://maps.googleapis.com/maps/api/staticmap?center=48.167432,10.533072&size=400x400&sensor=true&zoom=7

as image. set sensor=true if you're using gps sensor find location. otherwise set false.

to read image url:

getting image url (java)

how download image, , how know area pictured in it? found formula relate amount of meters (or whatever unit) "contained" in pixel (this function depends on latitude , zoom level of map). in case, how know pixels used map?

you pass pixels , zoom level image, information given solution, scale should easy calculate.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
