`Date(int year, int month, int date, int hrs, int min)`	Deprecated. As of JDK version 1.1, replaced by `Calendar.set(year + 1900, month, date, hrs, min)` or `GregorianCalendar(year + 1900, month, date, hrs, min)` .
`Date(int year, int month, int date, int hrs, int min, int sec)`	Deprecated. As of JDK version 1.1, replaced by `Calendar.set(year + 1900, month, date, hrs, min, sec)` or `GregorianCalendar(year + 1900, month, date, hrs, min, sec)` .
`Date(long date)`	Allocates a `Date` object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.
