Suppose Java had no Map classes and you had to create your own, using an underlying LinkedList. You may use the LinkedList class that is part of the Java API; you do not have to implement your own Linked List class. Write your own Map implementation for Maps in which both the key and value are Strings. Start with a MyEntry class with a String key and String value, plus any methods you need. Call your Map class MyMap. The class should have a LinkedList of MyEntries and isEmpty, size, put, get, remove(String key), and toString()methods. You may use the LinkedList class that is built into the JDK; you do not have to code the LinkedList functionality.
