Question$1(20$ Points$)$

Imagine a line of cars waiting to exit a parking garage. The car at the top of the line is at the toll booth. A car can join the line only at its end, after the last car currently in line. Barriers and lack of space prevent cars from joining the line anywhere else.

Design an ADT you can use to track the cars in the line. Specify each operating by specifying its purpose, by describing its parameters, and by writing a pseudocode version of its header. Then write a Java interface for the line's methods. Include Javadoc$-$style comments in your code.

Question $2(30$ Points$)$

Design a class LineOfCars that implements the interface described above. Use a resizable array in your implementation. Then write a program that adequately demonstrates your implementation.
