PLEASE HELP

**Member**

//Member(int memberId, String name)

Initialize the memberId and name instance variables appropriately with the values passed to the constructor.
Implement the appropriate getter and setter methods.



**Room**

Room()

Generate the roomNo using the static variable roomCounter. The value of roomNo should start from 500 and should be incremented by 1 for the subsequent values. Initialize the roomNoCounter in static block.

Initialize the capacity instance variable to 4.

Implement the appropriate getter and setter methods.



**Admin**

//assignRoom(Room[] rooms, Member member)

Assign a room to the member using the below conditions:

One room can accommodate 4 members.

Allocate the first room that is empty.

Once a room is fully occupied, only then a new room should be assigned.

Update the capacity of the allocated room accordingly.

Test the functionalities using the provided Tester class.


class Room {
    //Implement your code here
   
    //Uncomment the below method after implementation before verifying
    //DO NOT MODIFY THE METHOD
    /*
    public String toString(){
       return "Room\nroomNo: "+this.roomNo+"\ncapacity: "+this.capacity;
    }
    */
}

class Member {
//Implement your code here

//Uncomment the below method after implementation before verifying
   //DO NOT MODIFY THE METHOD
   /*
   public String toString(){
       return "Member\nmemberId: "+this.memberId+"\nname: "+this.name;
   }
   */
}

class Admin {
//Implement your code here
}


class Tester {
public static void main(String args[]) {
Room room1 = new Room();
Room room2 = new Room();
Room room3 = new Room();
Room room4 = new Room();
Room room5 = new Room();

Room[] totalRooms = { room1, room2, room3, room4, room5 };

Admin admin = new Admin();

Member member1 = new Member(101, "Serena");
Member member2 = new Member(102, "Martha");
Member member3 = new Member(103, "Nia");
Member member4 = new Member(104, "Maria");
Member member5 = new Member(105, "Eva");

Member[] members = { member1, member2, member3, member4, member5 };

for (Member member : members) {
admin.assignRoom(totalRooms, member);
if(member.getRoom()!=null) {
System.out.println("Hi "+member.getName()+"! Your room number is "+member.getRoom().getRoomNo());
}
else {
System.out.println("Hi "+member.getName()+"! No room available");
}
}
}
}

What is it you need help with?  Please elaborate.

It is always best to work through problems yourself.  Perhaps what you asked for help with was the "implement your code here" blocks?  If so, think about what the methods are named, and of course the (apparently) requirements list.  Consider how you would make those things happen using Java.  This really is where the fun begins.  You could create something at this point.  Along the way, remember you can always print out the states of things using code like this.   This is an example of how to dump room contents, assuming a room has been declared and has data in it.

    System.out.println(room);

One hint I would give: those "toString()" methods have been commented out.  

/* some code */

 takes code "out of commission".  Removing those from around the code will allow it to be executed again.

Have fun!

Welcome to the Ranch, John!

Our message editor has a "Code" button that can be used to wrap special tags around pre-formatted data such as Java code, XML, SQL and the like. If you use it, it will make your code samples much easier to read.
