Trouble with outputs

**tcw843** · July 25th, 2019, 04:26 PM

Hello everyone!

I'm having some issues with my program. Its a pretty basic travel agency program. I have been debugging it for about a week now. The user selects an option on the Destination Menu. They then select an option in the Transportation menu followed by the Upgrade Menu. Then it is suppose to display a Trip Report showing the Destination, Lodging Cost, Transportation option, Transportation Price, Upgrade option, Upgrade cost and finally the total Trip Cost before repeating the menus for other trips. Then a final report with the count of Rome trips, London trips, Key West trips, count of all trips and finally total Trip Sales. The issues I'm having is the Upgrade cost as well as the Total Trip Cost isn't showing up! I'm also having issues with the Final Report now showing the count of trips for each destination. I have spent about 5 hours tweaking my code but I cannot figure out where I'm going wrong. Any help or guidance would be much appreciated!

The issues I'm having is the Upgrade cost as well as the Total Trip Cost isn't showing up!

Can you post the current output that shows what you are talking about?

Can you explain what is wrong with that output? Add some comments that shows what you are talking about.

Also can you post the contents of the console window from when you execute the program that shows what the user's responses to the program are so they can be used for testing.

It suppose to show the number of trips as well. So Rome, Italy would have 1 but its not showing up either.

**Norm** · July 26th, 2019, 09:53 AM

I assume that the print out that was posted is correct as I do not see any comments in it that describes what is wrong.
For example I would expect to see this for a wrong value:

Transportation: Airplane
Transportation Cost: $ 500.00 <<<<< NO, this should be $750.00

**tcw843** · July 26th, 2019, 10:04 AM

ok hang on. i will edit the post.

--- Update ---

I edited my post with the output to show where the problems are. Thank you so much for your help.

**Norm** · July 26th, 2019, 10:08 AM

Ok, lets work through the problems one by one:

Upgrade Cost: $ 0.00 <------------ This should show 125.00

What variable's value is shown there? Where in the code is that variable given a value?

Add a print statement after every place in the code where that variable is given a value that prints a unique message and the value of the variable.
The print out will show you:
if the code is being executed
and where the value that is printed came from

**tcw843** · July 26th, 2019, 10:13 AM

UPGRADE_PRICE_LODGING is the variable and its declared with the class constant variables at the beginning.

public static final double UPGRADE_PRICE_LODGING = 125.00;

Can you show an example with adding a print statement?

**Norm** · July 26th, 2019, 10:25 AM

A sample print statement:

   someVar = 123.4;   // give the variable a value
   System.out.println("1 someVar="+someVar);   // show what value was assigned here
 
   ...  then in another part of the code
   someVar = 23.5;   // give the variable another value
   System.out.println("2 someVar="+someVar);   // show what value was assigned here

Every print statement should have a unique id. Above I used 1 and 2

UPGRADE_PRICE_LODGING is the variable

Is that the variable that is being printed for the line:

Upgrade Cost: $ 0.00 <------------ This should show 125.00

This is the statement that prints the above line:

		System.out.printf("%-30s%1s%8.2f", "Upgrade Cost: ", "$" , borrowedUpgradeCost);

That shows the value comes from the variable: borrowedUpgradeCost.
Trace back to see where that variable is given a value.

**tcw843** · July 26th, 2019, 10:36 AM

So everywhere there is UPGRADE_PRICE_LODGING, I should put this:

else if (upgradeSelection == 'B')
{
upgradeName = UPGRADE_NAME_LODGING;
upgradeCost = UPGRADE_PRICE_LODGING;
UPGRADE_PRICE_LODGING = 125.00;
System.out.println("The lodging upgrade is $125.00");
}

I have only written 4 programs before this one so I'm very new to Java so thank you for your patience.

**Norm** · July 26th, 2019, 10:49 AM

everywhere there is UPGRADE_PRICE_LODGING, I should put this:

Not necessarily. You want to see where the variable that is printed gets the value that is shown in the print out.
What about for the case that the value in the variable is 0? Do any of the assignment statements assign it 0?
If all the places where the variable is given a value also print out a message, the print out will show where the last value came from - it will be the last printed line before the report shows the value of 0.
If NONE of the statements print a message showing the value was changed then you know the value in the variable was not changed from its initial default value which is 0 for most primitive variables.

UPGRADE_PRICE_LODGING = 125.00;
System.out.println("The lodging upgrade is $125.00");

That print statement does not do what I suggested. It should show the name of the variable and the value in the variable:

System.out.println("UPGRADE_PRICE_LODGING="+UPGRADE_PRICE_LODGING);

However, UPGRADE_PRICE_LODGING is a constant and its value should never be changed. So what you posted does not make sense:

UPGRADE_PRICE_LODGING = 125.00;  //<<<<<<<< NOT POSSIBLE to change a constant

The variable is in this line: upgradeCost

   upgradeCost = UPGRADE_PRICE_LODGING;

**tcw843** · July 26th, 2019, 10:59 AM

I know that upgradeCost is declared with the main method variables at the beginning:

double upgradeCost = 0.0;

As far as borrowedUpgradeCost, I believe its given a value here:

public static char validateUpgradeSelection(Scanner borrowedInput)
{
char localUpgradeSelection = ' ';

System.out.printf("%-30s\n", "Upgrade Menu:");
System.out.println("****************************** ************************************************** ************************");
System.out.printf("%-4s%-25s%-2s%5.2f%s\n", "[A]:", UPGRADE_NAME_TRANSPORTATION,"$", UPGRADE_PRICE_TRANSPORTATION," per seat");
System.out.printf("%-4s%-25s%-2s%5.2f%s\n", "[B]:", UPGRADE_NAME_LODGING,"$", UPGRADE_PRICE_LODGING," per room");
System.out.printf("%-4s%-25s%-2s%5.2f\n", "[C]:", UPGRADE_NAME_TOURS,"$", UPGRADE_PRICE_TOURS);
System.out.printf("%-4s%-25s%-2s%5.2f\n", "[D]:", UPGRADE_NAME_ALL,"$", UPGRADE_PRICE_ALL);
System.out.printf("%-4s%-25s%-2s%5.2f\n", "[E]:", UPGRADE_NAME_NONE,"$", UPGRADE_PRICE_NONE);
System.out.println("****************************** ************************************************** *************************");
System.out.println("Please enter your selection here: ");
localUpgradeSelection = borrowedInput.next().toUpperCase().charAt(0);

**Norm** · July 26th, 2019, 11:11 AM

Ok if the variable: upgradeCost is the one with the problem, add a print statement after every place in the program where it is assigned a value.
The print out will show you if and where it is being assigned a value. If nothing prints out, it is not getting a value otherwise the last line printed will show what value it has been assigned.

borrowedUpgradeCost, I believe its given a value here:

Where??? I don't see any statement that gives it a value in that posted code.

**tcw843** · July 26th, 2019, 11:13 AM

So are you saying that

upgradeCost = 0.0; should be upgradeCost = UPGRADE_PRICE_LODGING;?

If that is the case, what happens if they choose another Upgrade option?

**Norm** · July 26th, 2019, 11:15 AM

So are you saying that

upgradeCost = 0.0; should be upgradeCost = UPGRADE_PRICE_LODGING;?

NO NO NO.

First you need to find out why the value that is printed is 0.
THEN you work through the code to see why the value is 0 and not the desired code.

**zemiak** · July 26th, 2019, 12:52 PM

I found this:

- here you forget brackets {} !! about line 150
(without it upgradeCost=0)
- and Calculations for Trip report must be before you print it with displayTripReport()
so
//--------------
else { //!!
upgradeName = UPGRADE_NAME_NONE;
upgradeCost = UPGRADE_PRICE_NONE;
} // !!

//Calculations for Trip report - moved here !
tripCost = lodgingCost + transportationCost + upgradeCost;

//Output Trip report
//----------------

- part of displayFinalReport() has incorrect format description in printf() this is with correction

//--------------
System.out.printf("%-30s%1s%s%d\n", "Count of Rome, Italy" ,"","Trips: ", counterRome );
System.out.printf("%-30s%1s%s%d\n", "Count of London, England" ,"","Trips: ", counterLondon);
