After modify the following code please split which part will be main.java file and which part will be hashtableclass.java file? Because I will use main.java IDE.

Modify the given programs by adding two methods in HashTableClass: Show Full code with output. Please Don't copy previous solution.
- Find and return the item with the maximum key;
- Find and return average of the keys in the hash table.
