        System.out.println("char / flag = " + flag);
        System.out.println("boolean / sex = " + sex);
        System.out.println("byte / number = " + number);
        System.out.println("short / age = " + age);
        System.out.println("int / workYears = " + workYears);
        System.out.println("long / money = " + money);
        System.out.println("float / score = " + score);
        System.out.println("double / income = " + income);
