Problem Description

A class called WaitList represents a set of students waiting to get into a course. The class relies on a Student class defined as follows:

/* YOU MAY NOT MODIFY THIS CLASS */ public class Student { private String name; private int id;

public Student(String sname, int sid) { name = sname; id = sid; }

public Student(Student student) { name = new String(student.name); id = student.id; }

public int getId() { return id; }

public String toString() { return name + " " + id; } }

For this quiz you will implement the WaitList class. The class specifications are:

Instance Variable

Student[] array; // Array that represents the list of students

Methods

• Constructor – Creates a waitlist with no students.

• add – This method takes as parameter a reference to the student to be added. The method

makes a copy of the student object and adds the copy to the end of the array representing

the waitlist. The size of the array will be increased by one.

• toString – Returns a string with the name and id of every student in the waitlist.

Information about each student will appear on a line by itself.
