## Question:

so what I'm trying to do is create a menu of food items with ArrayLists. My task is to complete the following definition of the static method profits that inputs an ArrayList items of MenuItems and returns an array of doubles. Each entry in the output is the difference between the price and the cost of the corresponding element of items. I have to process the result of each calculation involving money using the static method roundMoney.

``````    public class MenuItem
{
private String myName;

private double myPrice,
myCost;

private int    myCode;

private boolean myAvailability;

public MenuItem( String name, double price, double cost, int code, boolean available )
{
myName = name;
myPrice = price;
myCost = cost;
myCode = code;
myAvailability = available;
}

public String getName() { return myName; }
public double getPrice() { return myPrice; }
public double getCost() { return myCost; }
public int getCode() { return myCode; }
public boolean available() { return myAvailability; }

{
return getName() + " (\$" + getPrice() + ")";
}

public static double roundMoney( double amount )
{
return (int)(100 * amount + 0.5) / 100.0;
}

public static String printAmount( double d )
{
String s = "" + d;
int k = s.indexOf( "." );
if ( k < 0 )
return s + ".00";
if ( k + 1 == s.length() )
return s + "00";
if ( k + 2 == s.length() )
return s + "0";
else
return s;
}
}
//***********************************************************************
{
double[] profits = new double[items.size()];
for (int i = 0; i < profits.length; i++)
{
profits[i] = roundMoney (items.get(i).getPrice() - items.get(i).getCost());
}
return profits;
}
//***********************************************************************
public static void main( String[] args )
{

double[] t = profits( items1 );

for ( double d : t )
System.out.print( printAmount( d ) + " " );
}
``````

My expected result is: 4.98 3.34 5.25 5.79, but I keep receiving the error: TC1.java:30: error: cannot find symbol

double[] t = profits( items1 ); Could somebody please help me figure out what's wrong? Thank you!

You define your function `profits` with a capital "P."

``````public static double[] Profits(ArrayList<MenuItem> items)
``````

Change the line with the error to match the name of the function:

``````double[] t = Profits( items1 );
``````
