Answer
The basic process of deleting a message is to call setFlag() on the message and set the Flags.Flag.DELETED flag to true.
message.setFlag(Flags.Flag.DELETED, true);
Then, when you close the folder, deleted messages will be removed.
Be sure to open the folder for read/write access:
folder.open(Folder.READ_WRITE);
The following program demonstrates listing each message in the folder and prompting for deletion:
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
public class DeleteMessageExample {
  public static void main (String args[]) throws Exception {
    String host = args[0];
    String username = args[1];
    String password = args[2];
    // Get session
    Session session = Session.getInstance(
      System.getProperties(), null);
    // Get the store
    Store store = session.getStore("pop3");
    store.connect(host, username, password);
    // Get folder
    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_WRITE);
    BufferedReader reader = new BufferedReader (
      new InputStreamReader(System.in));
    // Get directory
    Message message[] = folder.getMessages();
