java example-rating songs

[ndrichim]

hello.i have a homework in java wich asks to create this program:
there would be n persons who are going to rate songs.
for n persons we will ask their name,surname,sex and age.after this each person will rate(vote) with points the song we have given to them.there are 15 songs and they are constant.at the end pint the most 10 rated song...
thnx :)

Great... but what are the problems that you are having? have you any code to show where the problem is occurring or any specific questions on the app? because you asked nothing you just told us about your assignment...

[ndrichim]

i would like you to help me build it.if you can :)

[DavidKroukamp]

i would like you to help me build it.if you can :)

This is and never has been a homework service center. It works on the basis you show us code or asks questions and we either show or help you to gain the knowledge in getting around/solving your problem.

[stultuske]

and to be a bit more specific: the amount of help you will receive also depends on how you define "help me build it".
btw, yes, yes we can, but we are not going to spend our time making your teacher believe you know what you are doing without seeing a bit of effort from your part.

[ndrichim]

ok then.how can we use the constructer examle(String name[],String surname[], int age[]){
....}
in void main ???

[DavidKroukamp]

ok then.how can we use the constructer examle(String name[],String surname[], int age[]){
....}
in void main ???

a constructor belongs in the class who's name it posses and not in any method...

public class X {
public X(String name[],String surname[], int age[]) {
}
   public static void main(String[] args) {
    }
}

[ndrichim]

ok until here we are ok.
but i have to build a void where i can get info from the user.
and after i finish this, i have to make void main to make this void work

[stultuske]

big no.
you can't get info from 'a void'. a method that has void as return type, returns nothing.

you'll need to use get- and set-methods, and I assume the names by themselves are quite self-explaining

[ndrichim]

ok lets do like this.i have solved this example all in the void main.but they ask to use contructor or classes.
this is what i've done, can you help me convert it in voids and constructors.
comments are non in englisht.no time to translate them.sorry.
have a look in my progam:

[stultuske]

do you have any experience with creating objects?
step 1: create an analysis (just write down what your app has to do)
step 2: underline all the nouns with red
step 3: underline all the verbs with blue

the red underlined words are the objects you'll have to create
the blue underlined words are functionalities (methods)

[ndrichim]

this is my finished example.all i have to do is to use contructor, objetct, or classes inside main class.can you convert ?

first, you need to create an object, it's that object's constructor and method's you're supposed to use.
and no, you can not create methods and constructors within your main method.

TERRIBLE song choices :( my ears bleed just looking at it, also arrays are 0 based.

there's no law forcing him to use the first index :)
as long as he doesn't try array[21], he'll be fine.

agreed but if we're gonna help him get better...

[jwenting]

using arrays at all is a terrible design decision... Should use a List or maybe a Set.
