public class Newsfeed {
  
  
  public Newsfeed(){
    
  }
  
  // Create getTopics() method below:
  public String[] getTopics() {
    String[] topics = {"Opinion", "Tech", "Science", "Health"};
    return topics;
  }
    
  

  public static void main(String[] args){
    Newsfeed sampleFeed = new Newsfeed();
    
    String[] topics = sampleFeed.getTopics();
    System.out.println(topics);
    
  }
}

My solution for step 2/8

it seems I am a bit confuse the result i got was “[Ljava.lang.String;@2aae9190” .
I thought we were suppose to see “Opinion”, “Tech”, “Science”, “Health” on the console from the System.out.println(topics);

public Newsfeed(){

}

public String getTopics() {

String[] topics = {"Opinion", "Tech", "Science" , "Health"};

return topics;

}

public static void main(String args){

Newsfeed sampleFeed = new Newsfeed();



String[] topics = sampleFeed.getTopics();

System.out.println(topics);

}

}

ah nevermind it seems the answer to my question is explained in the next lesson :sweat_smile:

I had this code but it would not take it
public String getTopics(){

}
any idea why

you can’t see any results when the method Newsfeed() which is empty! So remember that methods are the behavior of the class.
