Returning the next day?

Question

Hi, i hope somebody can help me, I'm new to Java and I'm stuck with some work that I am doing. I don't want an answer, just a hint as to where to get started.
I have created a class called Date, which uses switch statements to return a string of the date, when integer values are entered. I need to define a method public Date nextDay() to compute the next day, but I have no idea how to even start.
Here's the code in my original class, I need to emphasise that I do not want an answer, but a suggestion as to how to get started, I don't really understand what is meant by I need to have a return value of type Date because I do not really understand how this type would be represented.
package dates;
public class Date {
       Constructs a date with a given year, month, and day
       of the calendar.
       @param year a year between 94 and 07
       @param month a month between 1 and 12
       @param day a day between 1 and 31
    private int day, month, year;
    public Date(int d, int m, int y)
        day = d;
        month = m;
        year = y;
    public void setDay(int d)
        day = d;
       Returns the day of this date
       @return the day
    public String getDay()
        String sDay = "day";
        switch (day) {
            case 1: case 21: case 31:
                sDay = day+ "st"; break;
            case 2: case 22:
                sDay =day + "nd"; break;
            case 3: case 23:
                sDay = day+"rd"; break;
            case  4: case  5: case  6: case  7: case  8: case  9: case 10: case 11: case 12:
            case 14: case 15: case 16: case 17: case 18: case 19: case 20:
            case 24: case 25: case 26: case 27: case 28: case 29: case 30:
                sDay =day+ "th"; break;
            default: System.out.println("Please enter a valid date");
        return sDay;
    public void setMonth(int m)
        month = m;
       Returns the month of this date
       @return the month
    public String getMonth ()
        String sMonth = "";
        switch (month) {
            case 1: sMonth = "January"; break;
            case 2: sMonth = "February"; break;
            case 3: sMonth = "March"; break;
            case 4: sMonth = "April"; break;
            case 5: sMonth = "May"; break;
            case 6: sMonth = "June"; break;
            case 7: sMonth = "July"; break;
            case 8: sMonth = "August"; break;
            case 9: sMonth = "September"; break;
            case 10: sMonth = "October"; break;
            case 11: sMonth = "November"; break;
            case 12: sMonth = "December"; break;
            default: System.out.println("Please enter a valid month");
        return sMonth;
    public void setYear(int y)
        year = y;
       Returns the year of this date
       @return the year
    public int getYear ()
        int sYear = year;
        switch (year) {
            case 90: sYear = 1990; break;
            case 91: sYear = 1991; break;
            case 92: sYear = 1992; break;
            case 93: sYear = 1993; break;
            case 94: sYear = 1994; break;
            case 95: sYear = 1995; break;
            case 96: sYear = 1996; break;
            case 97: sYear = 1997; break;
            case 98: sYear = 1998; break;
            case 99: sYear = 1999; break;
            case 00: sYear = 2000; break;
            case 01: sYear = 2001; break;
            case 02: sYear = 2002; break;
            case 03: sYear = 2003; break;
            case 04: sYear = 2004; break;
            case 05: sYear = 2005; break;
            case 06: sYear = 2006; break;
            case 07: sYear = 2007; break;
            default: System.out.println("Please enter a valid year");
        return sYear;
    public String toString()
        return getDay()+" "+getMonth()+" "+getYear();

Well I'm sure that any basic java tutorial that included the words "object" and "create" would be able to help you, but I showed you above how to create a Date. See reply #2.
The general syntax for creating a new Object has two parts. First, you must declare a reference to the object:
Object myObject;Then you must instantiate a new object:
myObject = new Object();  //this must match a valid constructor for your type (in your case Date) You can of course do this in one line:
Object myObject = new Object();And for you, you want to use a subclass of Object, named Date (which is what you've called your class)
public Date returnNewDate() { //just a SAMPLE method returning a new Date object
Date date = new Date(10,12,2007);
return date;
}
