Figure out the best data structure to store poem data (Poem objects). See Poem class for reference
For example, a hashmap that has a key as a theme and a value that has a list of poems associated with that theme.
Maybe we could use a hashmap that has the author as a key and a list of the author's poems as the value
Think about what data structure is best to retrieve the poem to create the anthology. For example if we want 10 sad poem's from a specific author, what would be the best way to store and retrieve the data?
