i was wondering if someone can help me with this Java codes?
/**

// int pence = (_totalPence %100);
if (this.getPounds()>0 || this.getPence()>0)
{
return _currency + this.getPounds() + "." + this.getPence();
}
else
{
return "-"+ _currency + Math.abs(this.getPounds()) + "." + Math.abs(this.getPence());
}
}
/**
* This is to pull out the common code into a private helper method.
*/
private Money makeMoney(int total){
//convert total to pounds and pence,
// and resturn a new Money object with those parameters.
int pounds = (_totalPence/100);
int pence = (_totalPence % 100);
return new Money (pounds,pence);
}
/**
* Add another amount of Money to this one,
* returning a new Money object and leaving both this and other unchanged.
*/
public Money add(Money other)
{
_totalPence= _totalPence + other.getTotalPence();
return this.makeMoney(_totalPence);
}
/**
* Subtract another amount of Money to this one,
* returning a new Money object and leaving both this and other unchanged.
*/
public Money subtract(Money other)
{
_totalPence= _totalPence - other.getTotalPence();
return this.makeMoney(_totalPence);
}
}
I get 'ERROR: Cannot Find Symbol-Variable (anything I type here)' when I input a value using the constructor with currency. I am using BlueJ...not sure if the code i posted is correct but its the only codes i have and i am not very sure where is the error.
Thanks for help. Thanks Thanks
