Introduction

This year, we are going to implement, through a succession of assignments, a simple parking$-$lot simulator and

optimizer. For Assignment $1,$ we have modest goals though: we would like to read from a file the design and the

occupancy information of a parking lot, and perform some basic operations, for example, parking a car at a certain

spot in the lot. What you need to do in this assignment is illustrated with an example. Suppose we have a file

named parking. inf with the content shown in Figure $1.$

Figure $1$: Example input file

You will parse the input data and build the conceptual memory representation shown in Figure $2.$ More pre$-$

cisely, we get: $(1)$ an instance variable, lotDesign, instantiated with a with a two$-$dimensional CarType array $($of

size $45)$ and $(2)$ an instance variable, occupancy, instantiated with a two$-$dimensional Car array $($of the same size

as lotDesign$).$ These arrays will be populated with the data in the input file. The lotDesign variable represents

the design of the parking lot and the occupancy variable keeps track of the cars that are parked in the lot.

CarType is an enumeration class defined as follows:

In the input file, the letter $"E"$ means ELECTRIC, $"S"$ means SMALL, $"R"$ means REGULAR, $"$L$"$ means LARGE

and $"$N$"$ means Not Applicable $($NA$).$ The special NA value is used in the parking$-$lot design when a spot is usuitable

for parking a car $($e$.$g$.,$ when pillars or building facilities are blocking the spot$).$
