netbeans says that it won't compile because of the GetData commands. Please help tell me why it won't run.

Code:

public class Student {

    private String id,  firstname,  lastname;

    Student(String i, String f, String l) {
        id = i;
        firstname = f;
        lastname = l;
    }

    String getid() {
        return id;
    }

    String getfirstname() {
        return firstname;
    }

    String getlastname() {
        return lastname;
    }
}

Code:

import java.util.ArrayList;

public class Admissions {

    Student student;
    ArrayList<Student> list;
    int index;
    boolean found;
//2a
    Admissions() {
        list = new ArrayList<Student>();
    }
//2b
    void add(Student s) {
        list.add(s);
    }
//2c
    int size() {
        return list.size();
    }
//2d
    boolean empty() {
        return list.isEmpty();
    }

    Student get(int i) {
        return list.get(i);
    }

    //2e
    void search(String id) {
        int i = 0;
        int length = list.size();
        while (i < length && !found) {
            student = list.get(i);
            if (student.getid().equalsIgnoreCase(id)) {
                found = true;
            } else {
                i++;
            }
        }
        index = i;
    }
//2f 
    Student remove(int i) {
        return list.remove(i);
    }

    int getIndex() {
        return index;
    }

    Student getStudent() {
        return student;
    }

    boolean inList() {
        return found;
    }
