Class rosters include primary information of students. In this task you will learn how to use ADT Bag to implement a class roster with unspecified size. Step 1: Use a resizable array to implement ADT Bag and write a java program to let the user add, drop and search for a specific student using student ID (Duplication is not allowed). Your program should also provide the user with the following options: Class size If class is full or empty The number of students in the same academic level. o In your program, define a java class called Student with the following data fields: Student ID, first_name, last_name and academic level with: int , String, String and String data types respectively. Note that academic level can be: freshman, sophomore, junior or senior only. Step 2: Repeat step 1, but use a chain of linked nodes instead of a resizable array.

I have the implementation down with BagInterface.java and Student.java

I need help with the driver program to implement them. Not sure how I am supposed to allow the user to be able to search for the Student's ID or Name to remove them from the class. Thanks..

BagInterface.java

public interface BagInterface { public int getCurrentSize(); public boolean isEmpty(); public boolean add(T newEntry); public T remove(); public boolean remove(T anEntry); public void clear(); public int getFrequencyOf(T anEntry); public boolean contains(T anEntry); public T[] toArray(); }

Student.java

public class Student { private int Student_ID; private String first_name; private String last_name; private String academic_level; public Student() { Student_ID = 0; first_name = "n/a"; last_name = "n/a"; academic_level = "n/a"; } public Student(int ID, String first, String last, String year) { Student_ID = ID; first_name = first; last_name = last; academic_level = year; } // end of my constructor w/ parameters for student, mutators public void setID(int ID) { Student_ID = ID; }

public void setFirstName(String first) { first_name = first; }

public void setLastName(String last) { last_name = last; }

public void setAcademicYear(String year) { academic_level = year; } //my defined accessor methods public int getID() { return Student_ID; }

public String getFirstName() { return first_name; }

public String getLastName() { return last_name; }

public String getAcademicYear() { return academic_level; }

@Override public String toString() { return Student_ID + ", " + first_name + ", " + last_name + ", " + academic_level; } //end toString

}
