1,538 PointsI don't understand what I have to do in step 4 in the Main class... Can you please help me?
So I did well until now but I don't know what to do in Main.java int TODO section... I need a little help.
public class Forum {
private String topic;
// TODO: add a constructor that accepts a topic and sets the private field topic
public String getTopic() {
return topic;
}
public Forum (String topic){
topic = getTopic;
}
public void addPost(ForumPost post) {
System.out.printf("A new post in %s topic from %s %s about %s is available",
topic,
post.getAuthor().getFirstName(),
post.getAuthor().getLastName(),
post.getTitle()
);
}
*/
}
public class User {
private String firstName;
private String lastName;
public User(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
public String getFirstName (){
return this.firstName;
}
public String getLastName(){
return this.lastName;
}
}
public class ForumPost {
private User author;
private String title;
private String description;
private String description;
private String author;
private String title;
// TODO: add a constructor that accepts the author, title and description
public ForumPost(User author, String title, String description) {
this.author = author;
this.title = title;
this.descpription = description;
}
public User getAuthor() {
return author;
}
public String getTitle() {
return title;
}
public String getDescription() {
return description;
}
}
public class Main {
public static void main(String[] args) {
System.out.println("Beginning forum example");
if (args.length < 2) {
System.out.println("Usage: java Main <first name> <last name>");
System.err.println("<first name> and <last name> are required");
System.exit(1);
}
Forum forum = new Forum("Java");
User.getFitstName;
User.getLastName;
User author = new User();
// TODO: initialize the forum post with the user created above and a title and description of your choice
ForumPost post = new ForumPost();
forum.addPost(post);
// */
}

The firstName
and lastName
for the User
constructor are held in the args
which are passed into the main
method when the code is run. The args
is an array of strings and the first two elements of this array contain the names you need. Pass the first two elements, one at a time, into the User
constructor:
// TODO: pass in the first name and last name that are in the args parameter
User author = new User(args[0], args[1]);
Make sense?
Steve.
