macOS Quick Java Question

[RossMc]

Hi,

Just wondering if someone could answer this for me.

I need to write these three classes going off this UML diagram.

I have wrote them all and the Room & MeetingRoom class's compile fine but on the Bedroom class this line shows up wrong.

Bedroom(int, double, String)
{

}

It says <identifier> expected.

Based only on that, I'd say name your parameters. Posting more code might help, though.

In your method signature, you supplied the argument types, but not variable names

This is the code I have

Room

public class Room
{
int roomNumber;

double rate;

String customer;


Room()
{

}


Room(int n, double t)
{

}

void bookRoom(String cust)
{

}

void clearBooking()
{

}

String getCustomer()
{
return customer;
}

double getRate()
{
return rate;
}

int getRoomNumber()
{
return roomNumber;
}

public String toString()
{
return customer;
}

}

MeetingRoom

public class MeetingRoom extends Room
{
int seatingCapacity;

MeetingRoom(int t, double r, int c)
{

}

int getCapacity()
{
return seatingCapacity;
}

public String toString()
{
return customer;
}

}

Bedroom

public class Bedroom extends Room
{
String roomtype;

Bedroom()
{

}

Bedroom(int, double, String)
{

}

String getType()
{

return roomtype;
}

public String toString()
{

return roomtype;
}



}

I believe jmuchrisf is correct. In "Bedroom", you provided the argument types, but no variable names.

Try this instead:

Bedroom(int a, double b, String s)
{

}

Thanks for the reply.

I used the names from the Room class.
