Need assistance on multiple errors

Question

Hi everyone,
I have trouble compiling my Java program due to some errors shown below and would like to seek your help:
1) I have a couple of these error:
Enumeration enum = objectsMoved.elements();
Error msg: "Enumeration cannot be resolved"
Is ii because I am missing out on some Java packages or libraries?
2) import java_cup.runtime.Symbol;
Error msg: "The import *java_cup* cannot be resolved"
Where can I obtain this package?
3) The import junit cannot be resolved
Error msg :" The import *junit* cannot be resolved"
Where can I obtain this package?
4) getContentPane().add(aboutLabel, new com.symantec.itools.awt.GridBagConstraintsD(0,0,3,1,1.0,1.0,java.awt.GridBagConstraints.CENTER,java.awt.GridBagConstraints.BOTH,new Insets(0,0,0,0),0,0));
Error msg: "*com.symantec* cannot be resolved to a type"
5) import edu.umd.cs.jazz.*;
import edu.umd.cs.jazz.component.*;
import edu.umd.cs.jazz.event.*;
import edu.umd.cs.jazz.util.*;
Error msg: "The import edu cannot be resolved"
Where can I find the edu import? Or is it that I have to connect to a CVS repository?
6) public MessageFactory() {
     this(Platform.defaultPlatform);
Error msg: "Platform cannot be resolved"
Sincerely looking forward to your favorable assistance. Thank you!
Best regards,
