In this experiment you are expected to gain knowledge on basic JAVA programming. The program you are going to develop will deal with variables, loops, string operations, file read and write operations. Besides the programming task, you will also learn to comply with coding standards.

1. Problem Definition

In this experiment you are expected to write Java code that calculates the calories by considering taken and burned calories during the day for the healthy life of the people. You will be given three text files as follows:

1.1 Text for information of people (people.txt)

This text file includes personal information of each person, which are person ID (personID), name (name), gender (gender), weight (weight), height (height) and date of birth (dateOfBirth) as shown in following table. Every item in the file separated with a tab character. This text file contains up to 50 items.

[person ID] tab [name] tab [gender] tab [weight] tab [height] tab [date of birth] newline

[person ID] tab [name] tab [gender] tab [weight] tab [height] tab [date of birth] newline

Example content of people.txt

12345 ahmet male 78 175 1987
12346 ahmet male 92 189 1990
12378 …….. gizem female 61 172 1986

1.2 Text for food (food.txt)

This text file includes information of foods, which are food ID (foodID), name of food (nameOfFood) and calorie count (calorieCount) as shown in the following table. Every item in the file separated with a tab character. For each food, 1 portion is 100 grams and the calorie count in the table is calculated for 1 portion. ID of fruits groups start with 10.., ID of meal groups start with 11.., ID of dessert groups start with 12.. and they consist of a 4-digit number. This text file contains up to 100 items.

[food ID] tab [name of food] tab [calorie count] newline

[food ID] tab [name of food] tab [calorie count] newline

Example content of food.txt

1001 apple 57

  • spaghetti 131
  • lahmacun 185

……

1201 baklava 521

…….

1.3 Text for sport activities (sport.txt)

This text file includes information of sport, which are sport ID (sportID), name of sport (nameOfSport) and calorie burned (calorieBurned) as shown in the following table. Every item in the file separated with a tab character. The calories burned for each sport are calculated for 60 minutes. ID of sport activities start with 20.. and they consist of a 4-digit number. This text file contains up to 100 items.

[sport ID] tab [name of sport] tab [calorie burned] newline

[sport ID] tab [name of sport ] tab [calorie burned] newline

Example content of sport.txt

  • swimming 400
  • running 300

…..

2013 tennis 275

……

2. Calculation of daily calorie needs

The daily calorie needs (dailyCalorieNeeds) of people vary by gender, age, height and weight. Therefore, it will be calculated separately for men and women as follows:

The daily calorie needs (dailyCalorieNeeds) should always be rounded to the closest integer value.

3. Text for input (command.txt)

Each line of the input file named as command.txt consists of either person ID (personID), food ID (foodID) and the number of portions (numberOfPortion), or person ID (personID), sport ID (sportID) and sport duration (sportDuration) as shown in the table below. During day, a person may add food ID that is eaten and sport ID that is done into this file. The print(personID) command should write the current calorie status of the specified person in command.txt file to monitoring.txt file. The printList command should write calorie statuses of all people given in command.txt file to monitoring.txt file. The expected output format is given in section 4.

[person ID] tab [food ID] tab [number of portions] newline [person ID] tab [sport ID] tab [sport duration] newline ….. print(personID) newline [person ID] tab [sport ID] tab [sport duration] newline printList newline …..

Example content of command.txt

12345 1001 2

12378 1002 3

…..

print(12345)

12345 2001 45

12378 1001 1 printList

……

4. Text for output (monitoring.txt)

You are expected to write output of your program to a text file named as monitoring.txt for persons specified in command.txt file. This text file should include the following information for each person in order as shown in the following table: name (name), age (age), daily calorie needs (dailyCalorieNeeds), calories taken (caloriesTaken), calories burned (caloriesBurned) and result (result) for print (personID) and printList. If the result is a number less than zero, it means that a person has taken less calories than they should take during a day. On the other hand, if the result is greater than zero, a person has taken more calories than they should take during a day. Daily calorie needs (dailyCalorieNeeds), calories taken (caloriesTaken) and calories burned (caloriesBurned) should always be rounded to the closest integer value. Therefore, the result (result) will automatically be an integer. Also, the output file should include person ID (personID), calories taken, name of food (nameOfFood), calories burned and name of sport (nameOfSport) to keep track calories burned and taken for a given person in input file. Every item in the file separated with a tab character

[person ID] tab has tab taken tab [calories taken]kcal tab from tab [name of food] newline

*************** (There will be 15 stars ) newline

[person ID] tab has tab burned tab [calories burned]kcal tab thank tab to tab [name of sport] newline

*************** (There will be 15 stars ) newline

[name] tab [age] tab [daily calorie needs] tab [calories taken] tab [calories burned] tab [result] newline

*************** (There will be 15 stars ) newline

[name] tab [age] tab [daily calorie needs] tab [calories taken] tab [calories burned] tab [result] newline *************** (There will be 15 stars ) newline

……..

Example content of monitoring.txt

12345 has taken 200kcal from apple***************12356 has burned 100kcal thanks to tennis***************ahmet 27 1897kcal 2300kcal 400kcal +3kcal
***************ahmet 27 1897kcal 2300kcal 400kcal +3kcal
gizem 25 1789kcal*************** …….. 1900kcal 430kcal -319kcal

5. Example content of input and output file

In this experiment, you will be given an input file (command.txt) as below and you are expected to create an output file as shown below (monitoring.txt) by considering this given input file. The values in the example content of files given above (section 1.1, 1.2 and 1.3) are taken into consideration in this input and output files.

command.txt

12345 1102 4

12378 1101 3 print (12345)

12345 2001 45

printList
