where are the args passed?

I don't know where to pass args if I'm not using a command prompt...

ForumPost.java
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
}
User.java
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;
  }

}
Forum.java
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());
  }
}
Example.java
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);
  }
}

In this case arguments mean arguments passed to a method like this: object.method(argument1, argument2, ...)

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