my work:

public void addStudent(students st) {

///check if student is not in the list

if (hasStudent(st) < 0) {

studentList.add(st);

}

}

public void WASTA(students st, int index) {

///check if student is not in the list

if (hasStudent(st) < 0) {

studentList.add(index, st);

}

}

public students removestudent(students st) {

if (studentList.remove(st)) {

return st;

} else {

return null;

}

}

//// print array

public void printList() {

for (students stu : studentList) {

System.out.println(stu);

}

}

}

Student class :

public class students {

private String name;

private String Id;

public students(String n, String r) {

this.name = n;

this.Id = r;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getId() {

return Id;

}

public void setId(String Id) {

this.Id = Id;

}

// for checking if name and id are equal

public boolean equals(Object stx) {

students other = (students) stx;

if (!name.equals(other.name)) {

return false;

}

if (!Id.equals(other.Id)) {

return false;

}

return true;

}

public String toString() {

return "Name: " + name + ", ID: " + Id;

}

}

Main class:

public static void main(String[] args) {

course oop = new course("oop", "ITBP219");

course DS = new course("Data Structure", "ITBP319");

students st = new students("Zina", "9991");

oop.addStudent(st);

st = new students("Khawla", "8882");

oop.addStudent(st);

st = new students("Alia", "7773");

oop.addStudent(st);

st = new students("Hajar", "6664");

oop.addStudent(st);

st = new students("Bakhita", "5555");

oop.addStudent(st);

System.out.println("**First List**");

oop.printList();

///if we want to check and find a student

students findStudent = new students("Alia", "7773");

if (oop.hasStudent(findStudent) >= 0) {

System.out.println();

}

//

// System.out.println("**Second List**");

// students RMStudent = new students("Zina", "9991");

// oop.removestudent(RMStudent);

//

// oop.printList();

//

// System.out.println("**Third List**");

// st = new students("Bakhita", "5555");

// oop.WASTA(st, 0);

// oop.printList();

System.out.println("**Second List**");

}

}

For this assignment, do the following:

1- In the class, we have created Student Class, Course class and Main class. Inside of these classes, we have created various methods. Go to the Course class, and create a method inside the Course class that sort the students base on alphabet (2points). The method name should be SortStudentsName (1point)

2- Go to the Main class, and test the Sort method. So it sorts the students names (1Point)

3- Print the students list before and after the sorting (1Point)

4- Upload in blackboard the complete code for the 3 classes in single WORD file (1Point)

5- In the word file (add a print screen of the result) (1Point)

6- Remove the previous names and ID of the students, and add new students name and ID to the course of OOP, as follow (1Point):

Zina, 9991

Khawla, 8882

Alia, 7773

Hajar, 6664

Bakhita, 5555
