    Hi, my problem is, i know how to create an array of Strings, BUT, how can i import a file into the string array?

            //Points
            int points, player1Pts = 0, player2Pts = 0, change;
            String card;
            char player;

    i thought of
     while (InputCards.eof () != true)
            {
            card = InputCards.readString ();
            deck = deck[card];
     
            }
    but it keeps returning ( deck = deck[card]; ) this type of expression, "java.lang.String", is not numeric

    You must keep track of the current index - you cannot access an array index using a String object
    In Pseudo-code
    int counter = 0;
    while ( ... ){
         card = InputCards.readString ();
        deck[counter] = card;
        counter++;
    }

    }

    You need a counter to keep track of where you are.

    counter++ increments itself by 1.
