Java basic knowledge strengthening the data class of 90:date class and its methods

1. Overview of the Date class

Class date represents a specific moment, accurate to milliseconds

2. Construction method

 Public Date (): Creates a day object based on the current default millisecond value   Public Date (long date): Creates a Date object based on the given millisecond value

3. Member Methods

 Public Long getTime ()  Public void settime (long time)

4. code example:

1  Packagecn.itcast_01;2 3 Importjava.util.Date;4 5 /*6 * Date: Indicates a specific moment, accurate to milliseconds. 7  * 8 * Construction Method:9 * Date (): Creates a Date object based on the current default millisecond valueTen * Date (long date): Creates a Date object based on the given millisecond value One  */ A  Public classDatedemo { -      Public Static voidMain (string[] args) { -         //Creating Objects theDate d =NewDate (); -System.out.println ("D:" +d); -  -         //Creating Objects +         //Long time = System.currenttimemillis (); -         LongTime = 1000 * 60 * 60;//1 hours +Date D2 =NewDate (time); ASystem.out.println ("D2:" +D2); at     } -}
