7,011 Pointswhere are the args passed?
I don't know where to pass args if I'm not using a command prompt...
public class ForumPost {
private User mAuthor;
private String mTitle;
private String mDescription;
public ForumPost(User author, String title, String description){
mAuthor = author;
mTitle = title;
mDescription = description;
}
public String getDescription(){
return mDescription;
}
public User getAuthor() {
return mAuthor;
}
public String getTitle() {
return mTitle;
}
// TODO: We need to expose the description
}
public class User {
private String mFirstName;
private String mLastName;
public User(String firstName, String lastName) {
// TODO: Set the private fields here
mFirstName = firstName;
mLastName = lastName;
}
public String getFirstName(){
return mFirstName;
}
public String getLastName(){
return mFirstName;
}
public void setFirstName(String firstName){
mFirstName = firstName;
}
public void setLastName(String lastName){
mLastName = lastName;
}
}
public class Forum {
private String mTopic;
public String getTopic() {
return mTopic;
}
public Forum (String topic) {
mTopic = topic;
}
public void addPost(ForumPost post) {
System.out.printf("New post from %s %s about %s.\n",
post.getAuthor().getFirstName(),
post.getAuthor().getLastName(),
post.getTitle());
}
}
public class Example {
public static void main(String[] args) {
System.out.println("Starting forum example...");
if (args.length < 2) {
System.out.println("first and last name are required. eg: java Example Craig Dennis");
}
Forum forum = new Forum("Java");
// Take the first two elements passed args
User author = new User(args[0], args[1]);
// Add the author, title and description
ForumPost post = new ForumPost(author,"The Title", "Description of my forum");
forum.addPost(post);
}
}

7,011 PointsI think there was a logic error somewhere I decided to just redo the tasks and it worked. Thanks for the quick response time though.
