simple problem - code wont compile

[dirtycash]

Code:

public class Hotel {
    public static final int ROOM_PRICE = 20;
    public static final int SEAVIEW_SUPPLEMENT = 5;
    public static final int SINGLE_OCCUPIER_SUPPLEMENT = 5;
    public static final int DINNER_PRICE = 9;

    //declaring
    private Room[] array1;
    
    //An integer value representing the amount of money the hotel taken.
    private int hotelMoney = 0;
    
    //declaring 
    private static int freeRooms=number of rooms available in the hotel;
    
    //An integer value indicating the amount of free rooms available.
    public void freeRooms() 
    {
        freeRooms=freeRooms-1;
    }
}

it says a ";" is expected and highlights the following:

Code:

private static int freeRooms=number of rooms available in the hotel;

any help would be appreciated.

//declaring
private static int freeRooms; //number of rooms available in the hotel
