28,694 Pointsthe solution to step 1 is:
public class Forum {
private String mTopic;
public String getTopic() {
return mTopic;
}
public Forum(String topic){
this.mTopic = topic;
}
public void addPost(ForumPost post) {
/* When all is ready uncomment this...
System.out.printf("New post from %s %s about %s.\n",
post.getAuthor().getFirstName(),
post.getAuthor().getLastName(),
post.getTitle());
*/
}
