Answer 1

All the java.awt and javax.swing classes are part of the standard Java platform.

The javax.media classes are part of the Java Media Framework. You'd have to download and install that separately.

The MatchTemplate thing seems to come from here.

To find where a package come from, look through the Java SE API documentation or search for the package name on Google.

You need to put the relevant JAR files to your classpath while compiling and running your application which uses these classes (except if they are classes in the standard Java platform; these will be automatically available).
