Create a class named Appointment that contains instance variables startTime, endTime, dayOfWeek (valid values are Sunday through Saturday), and a date which consists of a month, day and year. All times should be in military time, therefore it is appropriate to use integers to represent the time. Create the appropriate accessor and mutator methods.

What will be an ideal response?

```
public class Appointment
{
private int startTime;
private int endTime;
private String dayOfWeek;
private String month;
private int day;
private int year;
/** Mutator methods */
public void setStartTime(int st)
{
/** valid range for military time is 0-2400 */
if((st >= 0) && (st <= 2400))
startTime = st;
}
public void setEndTime(int et)
{
/** valid range for military time is 0-2400 */
if((et >= 0) && (et <= 2400))
endTime = et;
}
public void setDayOfWeek(String dow)
{
/** Valid values are the strings Sunday – Saturday */
if(checkDayOfWeek(dow))
dayOfWeek = dow;
else
System.out.println("Fatal error....invalid day of week value!");
}
public void setMonth(String m)
{
/** Valid values are strings January – December */
if(checkMonth(m))
month = m;
else
System.out.println("Fatal error...invalid month value!");
}
public void setDay(int d)
{
/** Valid days in a date are the integers 1 – 31 */
if((d >= 1) && (d <= 31))
day = d;
}
public void setYear(int y)
{
if(y >= 0)
year = y;
}
