    cannot find symbol
    The compiler can not find a definition for the symbol or variable named in the error message.
    All variables used in a program MUST be defined so the compiler knows what type they are.

    Many of the "variables" that are not defined in the program look like they should be String literals.
    A String literal is letters inside of a pair of "s. This is a String literal: "ASDF"

    Look again at link that shows how to code switch statements. Compare the code in the tutorial to your code.

    Compilers are very fussy and exacting. If you don't follow the rules, there will be error messages.
    If you don't understand my answer, don't ignore it, ask a question.

    Like this example: switch (month) {
    case 1: futureMonths.add("January");
    case 2: futureMonths.add("February");
    case 3: futureMonths.add("March");
    case 4: futureMonths.add("April");
    case 5: futureMonths.add("May");
    case 6: futureMonths.add("June");
    case 7: futureMonths.add("July");
    case 8: futureMonths.add("August");
    case 9: futureMonths.add("September");
    case 10: futureMonths.add("October");
    case 11: futureMonths.add("November");
    case 12: futureMonths.add("December");
    break;
    default: break;
    }

    if (futureMonths.isEmpty()) {
    System.out.println("Invalid month number");
    } else {
    for (String monthName : futureMonths) {
    System.out.println(monthName);
    }
    }
    }
    }

    "ASDF" is a String literal with the 4 letters: ASDF
    Look in post #55 there are a lot of String litterals there with the names of the months in ""s

    Ask the compiler. It is usually correct.
