    <p>For my CS course I have to program a hotel checkin/checkout system. The program must be able to check people in and out. The programm assigns the first available room to a guest upon checkin. If no room is free, it will say so as well. The Hotel has four rooms. </p> <p>In the assignment it says there need to be 4 classes: Assignment5, Hotel, Room, &amp; Guest.</p> <ol> <li><p>Assignment5 class is for the interaction with the user.</p></li> <li><p>Hotel class has four rooms and all methods for operating the rooms.</p></li> <li><p>Room class has 1 guest. If the rooms is empty a guest can check in. If the guest is leaving the room needs to be emptied.</p></li> <li><p>Guest class: the guest has a firstname and a last name.</p></li> </ol> <p>In the menu there need to be 4 options: 1 show status of rooms available and occupation. 2 check in option 3 check out option 4 end program option.</p> <p>OK, so I know I should make my assignment for myself. However, I don't know what it is, but starting with assignments I have great problems cutting the thing up in smaller pieces. Also this assignment is to learn working with different classes and I don't really understand which sequence of steps i should take in this case.</p> <p>Can someone help me getting started by giving some tips? Have been staring at my screen for hours now and just thought I could use some little insights to get me started. Any help is greatly apprecieted!</p> <p>OK thnks for the help so far. </p> <p>*<strong>*First of all, MANY thanks for all your help, you guys are great! Have been at it for 7 hours straight now and still stuck. My problem now is that it doesn't compile. It says:</strong> </p> <pre><code>Java:28: checkIn(Gast) in Hotel cannot be applied to (java.lang.String) hotel.checkIn("Guido"); ^ 1 error </code></pre> <p>And maybe, can someone look if this way i put it now is a little bit on the right path? I do thank JavaGeek for his program, but i want to learn it by doing myself.</p> <p>up until now I have the following:</p> <pre><code> import java.util.Scanner; public class bopgave5 { public static void main(String[] args) { boolean opnieuw = false; do { int invoer = menu(); if (invoer == 2){ Hotel hotel = new Hotel(); hotel.checkIn("Guido"); opnieuw = true; } else if (invoer == 4) opnieuw = false; else opnieuw = true; } while (opnieuw == true); } public static int menu (){ Scanner sc = new Scanner(System.in); System.out.println("MENU: [1] Statusoverzicht"); System.out.println(" [2] Check-in"); System.out.println(" [3] Check-out"); System.out.println(" [4] Einde"); System.out.print("Uw invoer: "); int invoer = sc.nextInt(); return invoer; } } class Hotel { Kamer kamer1, kamer2, kamer3, kamer4; Hotel (){ kamer1 = new Kamer(); kamer2 = new Kamer(); kamer3 = new Kamer(); kamer4 = new Kamer(); } void checkIn(Gast nieuweGast) { if (kamer1.gast == null) { kamer1.gast = nieuweGast; System.out.println("Gast " + nieuweGast.naam + " krijgt kamer 1"); return; } else if (kamer2.gast == null) { kamer2.gast = nieuweGast; System.out.println("Gast " + nieuweGast.naam + " krijgt kamer 2"); return; } else if (kamer3.gast == null) { kamer3.gast = nieuweGast; System.out.println("Gast " + nieuweGast.naam + " krijgt kamer 3"); return; } else if (kamer4.gast == null) { kamer4.gast = nieuweGast; System.out.println("Gast " + nieuweGast.naam + " krijgt kamer 5"); return; } else { System.out.println("hotel is vol"); return; } } } class Kamer { Gast gast; Kamer() { gast = null; } } class Gast { String naam; Gast(String nieuweNaam) { naam = nieuweNaam; } } </code></pre>

    2. COWhat is a sense of asking "do my homework" questions? If you would specify one specific issue per question, somebody could help you. If I were you, I would look for good books on programming (e.g., Thinking in Java, GOF, Refactoring: Improving the Design of Existing Code) and read them.

    3. COI just really cannot figure it out for myself. I have the book INtroduction to Java Programming 3th edition 2001 by Liang. But the chapter about classes is not very clear to me. And especially the things with static/non static void etc are a mystery to me as well.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
