ANUC1110 Semester 2 -- 2018 Assignment 1

Assignment general specifications:

An effective online hotel booking system for querying and recommendation is

expected for this assignment. Three json files named day1.json, day2.json and

day3.json contain the booking information. Each file corresponds to one day,

documenting the booking records on that day. In a json file, each line is a booking

record on that day, specifying the traveler id and the choice of hotel. You can

open one of the three json files to see the structure of booking records.

The function of query module in your system is to retrieve booking record given

traveler id. Before that, we need to specify which day user wants to refer to, that is,

which json file user wants to retrieve. User can choose to retrieve the booking

information from the json files by entering number 1 to 4, where the details are as

following:

Entry from a user Data retrieved from json files

1 Day 1 booking information

2 Day 2 booking information

3 Day 3 booking information

4 Day 1, Day 2 and Day 3 booking information

After the specifying which json file we need to refer to, we can read in the booking

records (recognised by traveler id, hotel name) from json file and convert them

into a collection of java objects. Starting code has been provided using Jackson to

show how to get data from json file. You should complete the code to read

attributes of each booking record and construct proper objects to save the

information. (Hint: arraylist may be an efficient data structure for you)

3 / 7

After saving the given information, input a traveler id in console. Then output the

hotel name which the user has reserved on that day. If 4 is specified, output his /

her possible booking records for these three days.

An example is given here. If user enters 1, 2 or 3 to specify the day, then enters

the traveler id (1 - 20), the console should print out the possible booking

information as shown below. Your program does not need to print “[out]” and “[in]”,

they are used here to tell you whether the line is input that user types in or output

that your program should print out.

If no bookings have been found, the console should print out the following:

If user enters 4 to specify the day, then enter the traveler id (1 - 20), the console

should print out all the possible booking information as shown below:

[out]Please enter a number (1-4) to specify a day:

[in]1

[out]Please enter a traveler id:

[in]1

[out]Hotel name: Pacific; traveling time: Day 1

[out]Please enter a number (1-4) to specify a day:

[in]1

[out]Please enter a traveler id:

[in]20

[out]Hotel name: No record has been found

[out]Please enter a number (1-4) to specify a day:

[in]4

[out]Please enter a traveler id:

[in]1

[out]Hotel name: Pacific; traveling time: Day 1

[out]Hotel name: Pacific; Traveling time: Day 2

In the next stage, you are required to output an overview of the booking

distribution over different hotels on that day or three days. For example, if user

enters 1 at the first stage, your system should output the booking distribution on

day1, that is, every hotel has 20 percent of travelers on that day.

Your console should look like this at this stage:

Recommendation function is required in the next stage. Given the booking

records, the system should provide useful information for potential consumers.

Your program should output the hotel name with most empty rooms for

recommendation. The capacity of each hotel (total number of rooms) is given in

the json file named hotels.json, and the number of empty rooms is capacity minus

the number of rooms which have been occupied. In this part, your program could

only handle the situation when only one date is specified in the first stage.

[out]Please enter a number (1-4) to specify a day:

[in]1

[out]Please enter a traveler id:

[in]1

[out]Hotel name: Pacific; traveling time: Day 1

[out]The overview of booking is:

[out]Hotel name: Pacific; Proportion 20%

[out]Hotel name: Novotel; Proportion 20%

[out]Hotel name: Crown; Proportion 20%

[out]Hotel name: ibis; Proportion 20%

[out]Hotel name: Meriton; Proportion 20%

Your console should look like this at this stage:

You are required to:

1) Log in GitLab, fork the assignment repository from the course GitLab repository

in the following link: (1 mark)

https://gitlab.cecs.anu.edu.au/anuc1110/Assignment_1.git

2) Change the membership of your forked project by adding the teacher and tutor,

Ray Lau (u4561496) and Yujia (u6075459), as Reporter. (1 mark)

3) Open eclipse, import the project from your forked project. (1 mark)

4) Fix the program as following:

a) Print appropriate instructions for user’s input, that is, tell the user to type in

appropriate number to specify which day he/she wants to refer to. Then

according to the input from user, read specified json file(s) (day1 to day3) and

save the information in proper objects. You need record class to save booking

information from json. You may also need other classes to solve the problem.

(2 marks)

[out]Please enter a number (1-4) to specify a day:

[in]1

[out]Please enter a traveler id:

[in]1

[out]Hotel name: Pacific; traveling time: Day 1

[out]The overview of booking is:

[out]Hotel name: Pacific; Proportion 20%

[out]Hotel name: Novotel; Proportion 20%

[out]Hotel name: Crown; Proportion 20%

[out]Hotel name: ibis; Proportion 20%

[out]Hotel name: Meriton; Proportion 20%

[out]The recommended hotel is : Pacific

b) Print appropriate instructions for user’s input to specify which traveler

he/she wants to retrieve. Search traveler information according to traveler id,

input from console. And output the hotel name which he/her has reserved on

that day or three days with the format given in previous figures. If there is no

record for that traveler on that day, your system should print prompt message

as shown in previous figure. You will get part of marks if your system can only

handle the situation when only one day is specified in the first stage but

cannot deal with three days’ records. (3 marks)

c) Print booking overview for specified date(s). Every hotel with booking

record should be printed like above. You will get part of marks for this part if

your program can print the overview of each single day but does not work for

three days’ records. But hard code is not accepted, such as specifying hotel

names in your program instead of reading them from json file directly. (3

marks)

d) Print the recommended hotel based on the number of empty rooms in each

hotel. You need to construct appropriate container for hotel names and read

them from json file directly, hard code is not permitted. You can use the

intermediate result from c) for the number of occupied rooms of each hotel.

Together with the capacity of each hotel read from json file, calculate the

number of empty rooms in each hotel. Use reasonable method to find the

hotel with most empty rooms and print it out. (2 marks)

5) For part c) in question 4, design a JUnit test to check whether the distribution

for Day 1 is correct. You can use the given distribution information of day 1 (each

hotel occupies 20% of the market on that day). (1 mark)

6) For each solved problem, make sure it runs properly as required, then commit

and push the changes to your forked GitLab repository with relevant comments.

(2 marks)

7) Contribute to your team works. (1 mark)

8) Report quality (3 marks)

Assignment submissions:

Your submission needs to include the program via GitLab and a report that

includes:

1) Assignment Cover Sheet (available on the courses Wattle site).

2) The report that details your project including:

a) Structure of your project and its classes.

b) Report of how each part of your project has been done. For

example, how do you search passenger’s information, how to

determine whether there is a driver can take this passenger etc.

c) Screen shots of the running program for each major function fix.

The report is required to be submitted on Wattle by the due date (7:00pm, 19

September 2018) and a hard copy of it needs to be handed in to the teacher

on the due date in the classroom. One report per group.

Note: Failed to submit the report (either the electronic or hard copy) will apply

5 mark deduction out of your possible assignment result.

3) If you have used external resources for your assignment, you must cite the

source in both GUI and your report.
