importing unnecessary classes, does it makes my program run slowly or use more memory?

i mean, is it any bad to import classes that i don't use?

It has no impact at runtime, it's just a compile-time convenience.

import statement are not like c-style 'includes'. They are kind of like a PATH variable for the file. they tell the compiler "if you can't figure out what the 'Person' class is, try looking for it in the 'org.mycompany.people' package" - and since package structures are basically a list of directories...
