1,480 PointsHelp with Code Challenge Step 1?
For this part the instructions say to initialize the set in the constructor. This is easy enough, but I got the following compile error:
JavaTester.java:67: error: constructor Course in class Course cannot be applied to given types; Course course = new Course("Java Data Structures"); ^ required: String,Set found: String reason: actual and formal argument lists differ in length Note: JavaTester.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 1 error
This object was already made before I started the exercise, and I don't know where it is so I can't change it appropriately. Any help would be great.
Thanks!

28,694 Pointstask 1 is just the creation of the set, which may require an extra import statment.
package com.example.model;
import java.util.List;
import java.util.Set;
import java.util.HashSet;
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>(); //new HashSet<>();
}
public void addTag(String tag) {
// TODO: add the tag
}
public void addTags(List<String> tags) {
// TODO: add all the tags passed in
}
public boolean hasTag(String tag) {
// TODO: Return whether or not the tag has been added
return false;
}
public String getTitle() {
return mTitle;
}
}
