Working individually, write a possible contract $($specification$)$ as a Java interface for the

DictionaryADT using the Lab$3$StartingCode project.

$$ Your contract must include the required functionalities as defined in the problem

description as methods stubs with appropriate pre$-$conditions, post$-$conditions,

parameters, return values and expected exceptions using proper Javadoc notations.

$$ The specification should be documented so that the person who receives it could write

an implementation without any extra information.

$2.$ Pair up with a classmate and complete the remaining steps.

$3.$ Compare and discuss the contract with your partner. Together, finalize the ADT to make

sure all functionalities are specified appropriately in the contract.

$4.$ Follow the steps discussed in class to develop a complete set of JUnit tests to cover the

functionality of each method. Include expected, boundary and strange values that are not

specified in the preconditions.

Note: Your tests should all fail as this point, as there is no implementation of a Dictionary

class yet. However, consider at this point whether there
