Searching an arraylist

[adelgado0723]

The assignment requires that I write a program to update, maintain and query students' records on an ongoing basis. It requires a few things, but there's one in specific that I'm stuck on.
This is my Student class:

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;
    }
}

This is my Admissions class:

Code:

import java.util.ArrayList;

public class Admissions {

    Student s;
    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 isempty() {
        return list.isEmpty();
    }
//2e
    void search(String key) {
        if (list.s.getid().equalsIgnoreCase()) {
            ;
        }
    //Prof. didn't tell us how to do this. We need to figure it out, but I think it's with a while loop.
    }
//2f 
    Student remove(int i) {
        return list.remove(i);
    }
}

My problem is under 2e. I need to "given an id number, locate that record on the list"
Thanks!

Here is the loop to go through each student and check their id against the key. If this doesnt help, it should get you close enough to get the rest of your logic. Let me know.

Code:

    for (Student temp : list)
    {
      if (temp.getid()==key)
      {
        found=true;
      }
    }
