Java Assignment using netbeans

Requirements

One class, one file. Don't create multiple classes in the same .java file.

Don't use static variables and methods

Encapsulation: make sure you protect your class variables and provide access to them through get and set methods

Create 6 classes:

app

address

zipcode

student

group

person

The application app will:

create 4 addresses

create 4 students

create a group with a name and 4 students

Then using the group object that was createddisplay the group information using the group method displayInfo( )

displayInfo( ) uses the method getInfo( ) in the student class

the students will be listed sorted by last name as specified below.

The address class has the following attributes

street (a string with address number and street name)

city

state

zipcode

The zipcode class has the following attributes:

number

complement

The person class has the following

attributes:

first name

last name

age

address

methods

getInfo( ) which returns the complet person information as a String

The student class extends the class person and implements the Comparable interface, and has the following

attributes:

id

major

gpa

methodsgetInfo( ) which returns the complet student information as a String

getInfo( ) overrides getInfo( ) from person

compareTo( )

compareTo( ) overrides compareTo( ) from Comparable

The group class has the following attributes:

name

4 students in an array

the array should be sorted by last name

sort will be done using the sort method available in Java's Arrays (Links to an external site.)Links to an external site. class or in the ArrayList (Links to an external site.)Links to an external site.class, that's why you need to implement the comparable interface in the student class.

methodsgetInfo() which returns a String with the group's name and student's information

getInfo uses the student's method getInfo( ) to retrive each student's information

displayInfo( ) uses a "System.out.println" to display the group name and students information

getAverageGPA() which calculates the average GPA in the group and returns a double number

search(int n) which searches for a student in the group with the id as input parameter and returns a student object. If the student is not found, it returns null
