I think you need to think again. Are you supposed to enter 7 cities with populations? Do you have a City class? With name and population as fields?
Why are you using option panes rather than a Scanner?

You're right. I realized that they are redundant the moment i finished to post.

I am supposed to ask the user which city he wants the population to be added and then print the totals of each city. I do not have a City class. And because we are supposed to use OptionPane for this one.


Using this code in Case 1. It is working so far, i can obtain the number of people living in City 1 and the print the total value of the people living in there. However i can add a maxium of 8 values(because my array is of 8 thinking of the 7 cities).

But the thing is that i want to add the values of people living in City 1 in just the index 0 of my array. I'm not sure if that possible without using an array of array. Or should i use an array for each city?

To clarify: city.getInfo comes from City class, that method is used to obtain and store the value of the city population.

Hi guys, i have an assignment in which the user is asked for the number of city he would like to access, and when he does, he inserts the number of people living in it. The thing is i'm supposed to save the number of people living in each city in an array and then print all of them.

I have this so far,

Alright, i'm using case to access the "city" the user wants, it is probably poorly used and the "if" inside of it is redundant.

The other problem i'm having is that i have no idea how to insert the value of people living in certain city inside of certain index. For example i want to store the people living in city 1 inside the index 0 of the array, and so on. Any help would be appreciated. I'm trying to learn as much as i can and i'm researching on how to do it but i would like some help as well.

Consider a quiz. Remember how it works. You ask competitors questions and they get marks (or otherwise) for answers. You appear to have classes for the questions and the time, but do you have classes for the whole quiz or the competitors?

Oh yes, the Question class involves both, questions and answers. Besides the time there is the Frame time for everything related to the interface of the game(however i'm testing it on the console itself). I have a Level class that will check the advance of the player(5 questions each level) and finally the User class.

Hey guys,

I'm new to the forum and programming in general. Currently on week 9 of Java lessons and i've been told to made a "game" for week 15, and i picked some sort of Quiz Up clone.

The thing is i'm not sure about one thing, for example i have a class called Question and another class called Time. So basically whenever the user picks a wrong answer, the question is passed and -5 seconds of the total time are substracted. If the user picks the correct answer then +5 seconds are added to the total time.

I have my question class with a method to check the answers and but i haven't done the time thing in the Time class because i don't know how to connect the choices made my the user in Question class to a method that adds and substract seconds in another class.
