having issues with importing from jar file

In this assignment, you will black$-$box unit test the Reservation class of a small bed & breakfast reservation system. You will be given a Java jar file that includes:

$1)$ a Java class file of the Reservation class and

$2)$ a Java class file of the Assert library class that is used for testing.

Additionally, you will be given the specifications of both of these two given class files.

You will create four $(4)$ sets of black$-$box functional unit test cases $($composed of Selected Inputs, Expected Result, Actual Result, Pass$|$Fail$)$ to test the constructor and the public methods of the Reservation class. Then, using the provided $*.$jar files, you will code Java unit tests to execute your test cases and record their Pass$|$Fail verdicts. You will also explain your approach to create these black$-$box functional unit test cases and tests, the steps you followed, and the rationale behind your tests. You will reflect on the assignment and lessons learned.

To prepare for this assignment:

$1)$ Review the assigned reading for the week.

$2)$ Prepare a Java development environment. You can use the Java command line interface environment or any Java IDE $($e$.$g$.,$ Eclipse or NetBeans$).$ Java instructions $($e$.$g$.,$ how to compile, integrate the provided Java $*.$jar file into your development environment, etc.$)$ will be given using the command line interface. Adjust these instructions to your selected Java IDE if you choose to use one.

$3)$ Read the software development requirements for a small bed & breakfast reservation system $($SW$-$Dev$-$Req$-$Small$-$BB$-$Reservation$-$Sys$.$docx$)$in the attached Assignment$-$Resources$-$W$6.$zip file. These are the same requirements as those for week $2$ and week $4$ assignments but repeated here for completeness.

$4)$ Read the analysis model for a small bed & breakfast reservation system $($Analysis$-$Model$-$Small$-$BB$-$Reservation$-$Sys$.$docx$)$in the attached Assignment$-$Resources$-$W$6.$zip file. This analysis model was developed based on the software development requirements for a small bed & breakfast reservation system. This is the same analysis model as the analysis model for week $4$ assignment but repeated here for completeness.

$5)$ Read the specifications of the Reservation class of the small bed & breakfast reservati
