java - Handle ties when searching through arraylist -

in assignment, have make room booking program. there option count rooms made , show room seats. trying show more 1 room if there 2 rooms seats (tie). have working right print out room seats, confused on how implement ties.

class find largest room

public static void roomcount(arraylist<room> rooms) {     int largestroom = 0;     int largestnumofrooms = 0;     (int = 0; < rooms.size(); i++) {     if (rooms.get(i).getnumberofseats() > largestnumofrooms) {//determine largest room             largestnumofrooms = rooms.get(i).getnumberofseats();             largestroom = rooms.get(i).getroomnumber();         }     } 

room class

     public class room { scanner input = new scanner(system.in); private int roomnumber; private int numberofseats; private string reservedby = ""; private boolean reserved; private boolean hassmartboard;  /**  * attribute values user.  */  public room(int roomnumber) {     this.roomnumber = roomnumber;  }   public void getroomdetailsfromuser() {      system.out.print("enter number of seats: ");     numberofseats = input.nextint();     input.nextline();     system.out.print("does classroom have smart board? (y/n)");     hassmartboard = input.nextline().equalsignorecase("y");  }  public boolean ishassmartboard() {     return hassmartboard; }  public void sethassmartboard(boolean hassmartboard) {     this.hassmartboard = hassmartboard; }  public int getnumberofseats() {     return numberofseats; }  public void setnumberofseats(int numberofseats) {     this.numberofseats = numberofseats; }  public string getreservedby() {     return reservedby; }  public void setreservedby(string reservedby) {     this.reservedby = reservedby; }  public boolean isreserved() {     return reserved; }  public void setreserved(boolean reserved) {     this.reserved = reserved; }   public int getroomnumber() {     return roomnumber; }  /**  * update room reserved , reserved by.  */  public void reservethisroom(){     this.reserved = true;     system.out.println("enter name of person reserving room: ");     reservedby = input.nextline(); }   /**  * update room not reserved , clear reserved by.  */  public void releasethisroom(){     this.reserved = false;     reservedby = "";     system.out.println("room has been released\n");   }  public string tostring() {     string output = "\n\n******************************"             + "\nroom number: " + roomnumber             + "\nnumber of seats: " + numberofseats             + "\nreserved by: " + reservedby             + "\nreserved: " + reserved             + "\nsmart board: "+ hassmartboard;     return output; } } 

instead of storing largestroom in int can use list that. can followings

list<integer> largestroom = new arraylist<integer>();      if (rooms.get(i).getnumberofseats() >= largestnumofrooms) {//determine largest room         largestnumofrooms = rooms.get(i).getnumberofseats();         largestroom.add(rooms.get(i).getroomnumber());     } 

also need return values method.
