Problem in add method please help

import java.util.*;

public class BoatHireCompany
{
private ArrayList <Boat> theBoats;
// private RowBoat [] theRowBoats;
// private PedalBoat [] thePedalBoats; // private Arraylist <PedalBoat> thePedalBoat = new Arraylist <PedalBoat> (); //should this be in?
private int numRowBoats;
private int maxRowBoats;
private int numPedalBoats;
private int maxPedalBoats;

public BoatHireCompany (int numR, int numP)
{
theBoats = new ArrayList <Boat> (maxRowBoats);
theBoats = new ArrayList <Boat> (maxPedalBoats);
maxRowBoats = numR;
maxPedalBoats = numP;
numRowBoats = 0;
numPedalBoats = 0;

// theBoats = new ArrayList <Boat> (maxBoat);
// theRowBoats = new RowBoat [maxRowBoats];
// thePedalBoats = new PedalBoat [maxPedalBoats];
}


public boolean addRowBoat( Boat newBoats )
{

if ( numRowBoats == maxRowBoats )
{

return false;
}
else
{

theBoats.add(newBoat); THIS IS WHERE IT HAS A PROBLEM BUT I CANT SEEM TO FIGURE OUT HOW TO CORRECT IT
numRowBoats++;
return true;
}

}

Your code reads:
theBoats.add(newBoat);

While the parameter name is newBoats (note the "s"). Maybe thats the problem?
