Answer 1

From Sun's documentation on Using Package Members:

At first, packages appear to be hierarchical, but they are not. For example, the Java API includes a java.awt package, a java.awt.color package, a java.awt.font package, and many others that begin with java.awt. However, the java.awt.color package, the java.awt.font package, and other java.awt.xxxx packages are not included in the java.awt package. The prefix java.awt (the Java Abstract Window Toolkit) is used for a number of related packages to make the relationship evident, but not to show inclusion.

Importing java.awt.* imports all of the types in the java.awt package, but it does not import java.awt.color, java.awt.font, or any other java.awt.xxxx packages. If you plan to use the classes and other types in java.awt.color as well as those in java.awt, you must import both packages with all their files:

import java.awt.*; 
import java.awt.color.*;

If you have time, you will probably do well to read through the entire Packages trail from sun which goes over the basics and more complicated concepts thoroughly. From the language in your question, where you refer to the second import statements as including particular classes, it sounds like you're not understanding that you're actually referring to packages.
