Answer 1

您需要更改：

if (age>=18);

到

if (age>=18)

如果您使用了IDE并正确格式化了代码，那么这很明显：

前

    public static void age() {
        Scanner console = new Scanner(System.in);
        System.out.print("Enter age: ");
        int age = console.nextInt();

        if (age >= 18);
        {
            System.out.println("Legit to vote");
        }else
        System.out.println("Not Legit to vote");

    }

后

    public static void age() {
        Scanner console = new Scanner(System.in);
        System.out.print("Enter age: ");
        int age = console.nextInt();

        if (age >= 18) {
            System.out.println("Legit to vote");
        } else {
            System.out.println("Not Legit to vote");
        }

    }
