    Default Trouble with moving array through classes

    This is in my main class and method. I let the user select a character (called a champion), and then ,depending on which character they pick, I want to assign their stats as different values in an array. Each character having different array values imported from a secondary class. I have tried it both declaring the array in the primary class and taking it of either class. I haven't had a lot of progress and wasn't sure where else to look for an answer. Please answer with code, because sometimes I get confused between the different names of things.

     
    if ( champ1 == 0 ){//decides if character has been selected or not
                            System.out.print(
                                    "Pick a character:\n"//outputs menu
                                  + "1) Miss Fortune\n"
                                  + "2) Brand\n"
                                  + "3) Annie\n\n" 
                                  + "Enter your choice: ");
     
                            champ1 = input.nextInt();
                            switch(champ1){
                                case 1: 
                                    obj.missfortune();
                                    break;
                                case 2:
                                    int champarr1[] = new int[7];
                                    obj.annie(champarr1[]);
                                    break;
                                case 3:
                                    int champarr1[] = new int[7];
                                    obj.brand(champarr1[]);
                                    break;
                                default:
                                    System.out.println("Invalide entry, try again.");
                                    break;

    This is my secondary class.

     
    //subclass of reague of regends
     
    package reagueofregends;
     
    public class Characters {
     
        public int[] champ = new int[5];
     
        public int[] missfortune(){
            int[] champ = {1,2,3,4,5,6,7};
            return (champ);
        }
        public void annie(int[] champ){
            int[] champ = {1,2,3,4,5,6,7};
        }
        public void brand(int[] champ){
            int[] champ = {1,2,3,4,5,6,7};
        }
    }

    Default Re: Trouble with moving array through classes

    Are you getting compiler errors? If so, please copy the full text of the error messages and paste it here.

    The code with underlines is hard to read. Better to wrap the code with code tags.

    NOTE: Java passes args by value. Changing the value of the arg: champ will NOT change the the value of the variable used in the call.
    The contents of the array can be changed (for example: champ[0]) but not the variable: champ
    If you don't understand my answer, don't ignore it, ask a question.
