    numberOfSmoothiesTillPrize = numberOfSmoothiesTillPrize - 10;

All those writing answers, you are going to miserably fail in all your future ventures cause you can't follow simple instructions written by the owner.

C

Congratulations, you get a free smoothie!
You currently have 0 out of 10 smoothies needed for your next free smoothie.

good exercise

she said no answers :( ... , we now your a java master and you know the answer in sec... but keeeeeeeeeeeeeeeep it for your self dummy -_-

why are you posting the answer anyway? its freaking annoying.

I solve it

Nice code; It's ok

thanks 👍

Nice!

Option C is the correct answer.
Quite tricky.

I think I spotted a problem with this code. Let's assume that numberOfSmoothiesTillPrize is 6 going by this code the final log will show a negative value since the if statement has numberOfSmoothiesTillPrize-10 instead of 10- numberOfSmoothiesTillPrize.

I think I spotted a problem with this code. Let's assume that numberOfSmoothiesTillPrize is 6 going by this code the final log will show a negative value since the if statement has numberOfSmoothiesTillPrize-10 instead of 10- numberOfSmoothiesTillPrize.

Remember that code inside of the { } after an if statement is only executed when the condition inside the if statement is true.

The code "numberOfSmoothiesTillPrize = numberOfSmoothiesTillPrize - 10" is only executed when the if clause is true. The if statement in this case is:

  if(numberOfSmoothiesTillPrize >9)

This statement will be true only when the value of the variable numberOfSmoothiesTillPrize is greater than 9. Therefore the code inside the if statement will only execute when numberOfSmoothiesTillPrize is 10 or higher. This is why it will never be assigned a negative value.

c

the correct answer is c

Option C win

I support you!

if you think you fully understand the if/else syntax, take a look at this line of code that i have written for my app
int total = (5 + (whippedCream.isChecked() ? 2 : 0) + (chocolate.isChecked() ? 1 : 0)) * quantity;

int total = (5 + (whippedCream.isChecked() ? 2 : 0) + (chocolate.isChecked() ? 1 : 0)) * quantity;

syntax is fine and you managed well the implementation of if else statement using tertiary operator but cannot comment on desire output that you expect. price that's 5 is hard coded, on whipped cream checked it will add 2 and on chocolate checked it will add 1 to price/5 and will multiply result with quantity. A good approach though!

Its the best Course that I found on "Android Development"....
All the udemys' Android Development courses are trash made by some random guys just to loot our money, with no knowledge and idea of what the heck even they are talking in the course.

Option c

Salam awlad 9hab hh

ok done

I have some python skills, I feel it's easier to understand and migrating my old python skills into the java conditional statements. I realize that, after understand the sudo code it's easier to migrate over to any language. Thank You Udacity for make this course available for free.
