public class Simulation1

extends Simulation

A class which defines a specific lunch simulation seating scheme. This class completes the class outlined in Simulation. The parties will be seated at tables which are the same size as their party.

Field Summary

private Queue[]

waiting An array of queues to hold all of the parties that are waiting to be seated.

Constructor Summary

Simulation1(long seed1, long seed2)
Creates a new instance of the simulation.

Method Summary

protected void	addToQueue(Party p) If a table is not available for the party, the party will be added to a queue.
protected int	findTable(Party p) Attempts to find a table for the specified party.
protected void	freeTable(int tableSize) Frees a table of a specific size.

Constructor Detail

Simulation1

public Simulation1(long seed1,
                   long seed2)

Creates a new instance of the simulation. Also initializes array of queues, and initializes the EventTimer with the specified seeds.

Parameters:

seed1 - a seed to initialize the EventTimer

seed2 - a seed to initialize the EventTimer

Method Detail

findTable

protected int findTable(Party p)

Attempts to find a table for the specified party. Checks to see if a table for this party is available. The table must be the same size as the party. If there is no table available, -1 is returned.

Parameters:

p - the party to be seated

Returns:

the size of the table the party will be seated at; -1 if there is no table available

Overrides:

findTable in class Simulation

addToQueue

protected void addToQueue(Party p)

If a table is not available for the party, the party will be added to a queue. They will be added to a queue which contains other parties with size equal to the specified party's size.

Overrides:

addToQueue in class Simulation

freeTable

protected void freeTable(int tableSize)

Frees a table of a specific size. If there are other parties waiting for a table of the same size, the party which has been waiting the longest will be seated at the newly freed table.

Parameters:

tableSize - the size of the table to be freed

Overrides:

freeTable in class Simulation
