Answer 1

You can import java.util.* it work fine but when you import specific class instead of all class it take less time in importing but if you are importing too many classes from same package you can import all classes using package.* and it takes less time for jvm to fetch instead of taking one by one.

By convention you can use import package.* if you are using too many classes from same package.
