Lab3 help

Posted: Nov 8, 2006 11:08 PM

Hi,
I really need help about my lab3 of how debug the largeTrucksNeeded method and get it to work.I'm using BlueJ to test and run my program and webcat to see what BlueJ could not solve. Below are snippets code of my BigJob classes

public class BigJob
{

/**
* Returns the number of large trucks needed for this job.
* It's necessary to call both largeTrucksNeeded and smallTrucksNeeded to
* determine to total job requirements.
* Returns -1 if there are not enought small or large trucks for job.
*
* @return Number of large trucks needed
*/
public int largeTrucksNeeded()
{
int largeTrucksNeeded =
(int) (Math.floor(concreteAmount) / LARGE_TRUCK_SIZE);

if (largeTrucksNeeded <= largetruckcount)
{

return largeTrucksNeeded;
}
return -1;
}
/**
* Returns the number of small trucks needed for this job.
* It's necessary to call both largeTrucksNeeded and smallTrucksNeeded to
* determine to total job requirements.
* Returns -1 if there are not enought small or large trucks for job.
*
* @return Number of small trucks
*/
public int smallTrucksNeeded()
{
int smallTrucksNeeded = 0;

if (largeTrucksNeeded() >= 0 )
{
double remainderLarge =
concreteAmount - ( LARGE_TRUCK_SIZE
* largeTrucksNeeded());

smallTrucksNeeded =
(int)Math.ceil(remainderLarge / SMALL_TRUCK_SIZE);

}

else
{

smallTrucksNeeded =
(int)Math.ceil(concreteAmount - (largetruckcount *
LARGE_TRUCK_SIZE)) / SMALL_TRUCK_SIZE;

}
if (smallTrucksNeeded <= smalltruckcount)
{
return smallTrucksNeeded;
}
else
{
return -1;
}
}

Test BigJob

/**
* Number of large trucks needed.
*/
public void testLargeTrucksNeeded()
{
BigJob bigJob1 = new BigJob (60.0);
bigJob1.setLargeTruckCount(1);
assertEquals(-1, bigJob1.largeTrucksNeeded());
bigJob1.setLargeTruckCount(5);
assertEquals(4, bigJob1.largeTrucksNeeded());
bigJob1.setConcreteAmt(12.0);
assertEquals(0, bigJob1.largeTrucksNeeded());
}

/**
* Number of small trucks.
*/
public void testSmallTrucksNeeded()
{
BigJob bigJob1 = new BigJob (60.0);
bigJob1.setLargeTruckCount(0);
bigJob1.setSmallTruckCount(2);
assertEquals(-1, bigJob1.smallTrucksNeeded());
bigJob1.setConcreteAmt(21);
bigJob1.setSmallTruckCount(2);
assertEquals(-1, bigJob1.smallTrucksNeeded());
}

My question is what is why webcat take me away point on largetrucksneeded.
Thanks
