酒店菜单系统循环，Java

Question

我正在尝试制作一个小应用程序，向用户显示菜单并进行选择。到目前为止，我有这个：

 package hotel;
 import java.util.*;

 public class Hotel {

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    Room[] myHotel = new Room[10];
    myHotel[0] = new Room ();
    myHotel[1] = new Room ();
    myHotel[2] = new Room ();
    myHotel[3] = new Room ();
    myHotel[4] = new Room ();
    myHotel[5] = new Room ();
    myHotel[6] = new Room ();
    myHotel[7] = new Room ();
    myHotel[8] = new Room ();
    myHotel[9] = new Room ();

String roomName;
String menuEntry;
int roomNum = 0;
String[] hotel = new String[11]; 
for (int x = 0; x < 6; x++ ) hotel[x] = "";
initialise(hotel);


System.out.println("Enter one of the following:\nA) Add\nD)\nE)\nF)\nL)\nO)\nS)\nV) View all rooms\nInput:");
menuEntry = input.next();

if (menuEntry == "A")
{
while ( roomNum < 11 )
{
    for (int x = 0; x < 10; x++ )
    {
        if (hotel[x].equals("e"))System.out.println("room " + x + " is empty");
        }
            System.out.println("Enter room number (0-9) or 10 to stop:" );
            roomNum = input.nextInt();
            System.out.println("Enter name for room " + roomNum +" :" ) ;
            roomName = input.next();
            hotel[roomNum] = roomName ;
}
}


if (menuEntry == "V")
{
for (int x = 0; x < 10; x++ )
{
System.out.println("room " + x + " occupied by " + hotel[x]);
}
}

}   
private static void initialise( String hotelRef[] ) {
for (int x = 0; x < 10; x++ ) hotelRef[x] = "empty";
System.out.println( "initilise\n");
}
}

显示菜单，但是当输入一个条目时，循环结束并且＃34;内置成功＆＃34;显示。
