## 30.3 java.util.Date (JDK 1.0)

###

This class represents dates and times. It lets you work with them in a system-independent way. You can create a `Date` by specifying the number of milliseconds from the epoch (midnight GMT, January 1st, 1970), or by specifying the year, month, date, and optionally, the hour, minute, and second. Years are specified as the number of years since 1900. If you call the `Date` constructor with no arguments, the `Date` is initialized to the current time and date. The instance methods of the class allow you to get and set the various date and time fields, to compare dates and times, and to convert dates to and from string representations.

In Java 1.1, many of the date methods have been deprecated in favor of the methods of the `Calendar` class.

    public class Date extends Object implements Serializable, Cloneable {
        // Public Constructors
                public Date();
                public Date(long date);
            #   public Date(int year, int month, int date);
            #   public Date(int year, int month, int date, int hrs, int min);
            #   public Date(int year, int month, int date, int hrs, int min, int sec);
            #   public Date(String s);
        // Class Methods
            #   public static long UTC(int year, int month, int date, int hrs, int min, int sec);
            #   public static long parse(String s);
        // Public Instance Methods
                public boolean after(Date when);
                public boolean before(Date when);
