help with program please!

this is a program i am working on to display all dates in a given year.
I am new to Java. Was wondering if anyone could provide a simpler eay to do it .
Also I need help with how to make the month February to change from 28 days to 29 when there is a leap year.
here is my code: Sorry its a little messy
**************************************************

public class exerciseDate
{
public static void main(String[] arguments)
{

int year = 2008;
int month = 1;
int day = 1;

//January
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//February
while(day <= 29)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//March
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//April
while(day <= 30)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//May
while(day <= 30)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//June
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//July
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//August
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//September
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//October
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//November
while(day <= 30)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;
day = 0;
//December
while(day <= 31)
{

System.out.println(month + "/" + day + "/" + year);
day++;


}
month++;




}
}

Use a Calendar.

Code:

---

int year = 2008;

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, Calendar.JANUARY);
calendar.set(Calendar.DATE, 1);

// for each day in the year
while (calendar.get(Calendar.YEAR) == year) {
        // e.g. 01/01/2008
        System.out.printf("%1$tm/%1$te/%1$tY%n", calendar);

        // go to next day
        // accounts for the number of days in a month (including leap years)
        // (automatically "wraps", for example, January 32 is February 1)
        calendar.add(Calendar.DATE, 1);
}

---

Thank you !
