Hi Mario,

The two set methods would look something like:

public void setTitle(String title){
  this.title = title;
}

public void setNumPlay(int plays){
  this numPlay = plays;
}

They just set the values of the two private member variables. The two get methods do the opposite - they retrieve the values held within the private member variables and might look something like this:

public String getTitle(){
  return this.title;
}

public int getNumPlay(){
  return this.numPlay;
}

The isPopular method returns a boolean depending on whether numPlay is greater than 1,000. That might look like:

public boolean isPopular(){
  return numPlay > 1000;
}

That leaves you to create an instance of this class then call the `toString method on that. I'll leave that with you.

Steve.
