I had gotten some help from classmates for question 10. I used w3schools to help me with a few small things including: -Reading files: https://www.w3schools.com/java/java_files_read.asp -Hashsets: https://www.w3schools.com/java/java_hashset.asp -Hashmaps: https://www.w3schools.com/java/java_hashmap.asp -LinkedLists: https://www.w3schools.com/java/java_linkedlist.asp -Enums: https://www.w3schools.com/java/java_enums.asp these were mainly to just understand how certain things i didnt understand work and also to learn some of the keywords.
