Note: My own personal opinion is that trivial getters (and setters) should be formatted as follows:
public int getYear () { return year; }
public int getMonth () { return month; }
public int getDay () { return day; }
public String toString () { return (month + "/" + day + "/" + year); }
I made a correction to your toString () expression.
This is the program...
package dates;
public class Date {
protected int year;
protected int month;
protected int day;
public Date(int newMonth, int newDay, int newYear)
{
month = newMonth;
day = newDay;
year = newYear;
}
public int getYear()
{
return year;
}
public int getMonth()
{
return month;
}
public int getDay()
{
return day;
}
public int lilian()
{
final int SUBDAYS = 578100;
int numDays = 0;
numDays = year * 365;
if (month <= 2)
numDays = numDays + (month - 1) * 31;
else
numDays = numDays + ((month - 1) * 31)
- ((4 * (month - 1) + 27) / 10);
numDays = numDays + day;
numDays = numDays + (year / 4) - (year / 100) + (year / 400);
if(month < 3)
{
if ((year % 4) == 0) numDays = numDays - 1;
if ((year % 100) == 0) numDays = numDays + 1;
if ((year % 400) == 0) numDays = numDays - 1;
}
numDays = numDays - SUBDAYS;
return numDays;
}
public String toString()
{
return(month + "/" + "/" + year);
}
public class IncDate extends Date
{
public IncDate(int newMonth, int newDay, int newYear)
{
super(newMonth, newDay, newYear);
}
public void increment()
{
}
}
