Question: Quite often I see that programmers use full name of class in a program. For example like this:

java.util.Vector vect = new Vector();

I do not like such long lines, they are not so nice! Is not it easier to use the "import" in the beginning of program:

import java.util.*;

and then: Vector vect = new Vector(); ?

Answer: By using full class name in a program a programmer avoids names collision situation - a case when you could have your own Vector class in your package:

com.mypack.utilities.*

For example you have:

import com.mypack.utilities.*;
import java.util.*;

Compiler will not understand which Vector class you reffer in the line below:

Vector vect = new Vector();
The usage of full class name makes the situation clear.
