I'm confused on what I need to return
package com.example.model;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
public class Course {
private String mTitle;
private Set<String> mTags;
public Course(String title) {
mTitle = title;
// TODO: initialize the set mTags
mTags = new HashSet<String>();
}
public void addTag(String tag) {
// TODO: add the tag
mTags.add(new String(tag));
}
public void addTags(List<String> tags) {
// TODO: add all the tags passed in
for (String allTags : tags){
mTags.add(new String(allTags));
}
}
public boolean hasTag(String tag) {
// TODO: Return whether or not the tag has been added
return false;
}
public String getTitle() {
return mTitle;
}
}

Treehouse Project ReviewerWhat this is asking you to check is if your set "mTags" contains the tag that is passed in. Hmm....
public boolean hasTag(String tag) {
return mTags.contains(tag);
}
This will return either true or false whether or not the tag that you're searching for is in mTags.
Great job on the rest of the challenge!
