I was thinking of the former. Just as an example off the top of my head, maybe you're writing a class which does SQL stuff, and puts things into collections. If you write:

import java.sql.*;
import java.util.*;

You'll get a collision with the classname "Date", because there exists a java.sql.Date and a java.util.Date. If you instead wrote:

import java.sql.Connection;
import java.sql.Date;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;

Only if you do not specify the package name in front of the class name when declaring the variable, would there be a problem. But I see your point though, basically there is pro and cons to the issue.
