– ASSIGNMENT 5 –
CLASSES + ARRAYLISTS + SCANNER + CONSTRUCTOR + OVERLOADING
" Do it yourself "
- Taesik Kim, Ph.D.
I ) (30 pts.) - This assignment revisits the student parsing program from previous practices, but challenges you to restructure the component pieces of the program to create a cleaner, more succinct Main(). You will generate a People class of object and load an ArrayList with person objects, then report the contents of that ArrayList. To do so, you must
perform the following:
A) (15/30 pts.) - Create a class file “People.java” (which will generate People.class upon compile). People.java will have eight(8) methods to
1) read a .txt file ‘people.txt’
2) generate:
▪ List of all students AND teachers
▪ List of all students OR teachers
▪ List of all female or male students OR teachers
▪ List of female or male students OR teachers whose age is greater than or equal to given age
▪ List of female or male students OR teachers whose age is greater than or equal to given age1 and less than given age2
▪ List students OR teachers whose age is greater than or equal to given age
▪ List students OR teachers whose age is greater than or equal to given age1 and less than given
B) (3/30 pts.) – When you instantiate your class with new, you must use the text file name (eg. People p = new People ("people.txt"))
C) (10/30 pts.) – You are required to use “Constructor”, “ArrayList” and “Overloading” concepts.
D) Once your People.class is functional, generate a file “Assg05_yourName.java”.
Assg05_yourName.java should contain only one Main() method.
[Example of Main()] → This is an example. I will test all methods with deifferent values (teacher/student,
female/male, different age)
public static void main(String[] args)throws FileNotFoundException {
People p =new People("people.txt");

p.list(); p.list("s"); p.list("t","f"); p.list("s","f", 20);

// List of students AND teachers) // List of students // List of female teachers // List of female students whose age>=20

p.list("s","f", 15, 20); // List of female students whose age>=15 and
age<=20
p.list("s", 20); // List of students whose age>=20
p.list("s", 15, 20); // List of students whose age>=15 and age<=20
}
(line break, 11 pt)
E) (2/ 30 pts.) - The main() method of Assg05_yourName.java may not contain more than 5 lines of code.
1 ) This total does not include comments and documentation
2 ) This total does not include statements mentioned at the above section A) 2).
F) (-10 pts.) - Include appropriate program documentation and formatting including:
1) Your first and last name
2) Your contact information
3) Your student ID number
4) The date
5) A short description of the program’s function
6) Comments necessary to explain the operation of your program
7) Proper indentation
(line break, 11 pt)
G) Save your file as “Assg05_yourName.java” and upload to Canvas. Also upload “People.java”.(line
H) If you used someone else’s code (part or full), you will get -150 points. In some cases, you will be asked to
explain to me how your program does work.
II ) A Sample log of execution is as follow :
*Note: No user inputs are a part of this assignment
public static void main(String[] args)throws FileNotFoundException {
People p =new People("people.txt");
p.list("s","f", 15, 20);

}
