I was going through Kathy & Bert Bates book on
SCJP . In the last lesson on JAR file , i found the following text :
"When you say import java.util.*;you are saying "Use the short names for all of the classes in java.util package". You are not getting the java.util.jar classes or the java.util.regex packages!"
I could not understand the last line. When these jar and regex classes/package do belong to java.util package , how come they are not imported?
