Java > Logic-1 > alarmClock (CodingBat Solution)

Problem:

Given a day of the week encoded as 0=Sun, 1=Mon, 2=Tue, ...6=Sat, and a boolean indicating if we are on vacation, return a string of the form "7:00" indicating when the alarm clock should ring. Weekdays, the alarm should be "7:00" and on the weekend it should be "10:00". Unless we are on vacation -- then on weekdays it should be "10:00" and weekends it should be "off".

alarmClock(1, false) → "7:00"
alarmClock(5, false) → "7:00"
alarmClock(0, false) → "10:00"


Solution:

public String alarmClock(int day, boolean vacation) {
  if (vacation) {
    if(day > 0 && day != 6)
      return "10:00";
    else
      return "off";
  } else if (day > 0 && day != 6)
      return "7:00";
    else
      return "10:00";
    
}

    public String alarmClock(int day, boolean vacation) {
    boolean weekday = day < 6 && day > 0;
    if (weekday && !vacation)
    return "7:00";
    else if ((weekday && vacation) || (!weekday && !vacation))
    return "10:00";
    return "off";
    }

    return (vacation ? (day == 0 || day == 6 || day == 7 ? "off" : "10:00") :
    (day >= 1 && day <= 5 ? "7:00" : "10:00"));
