Java中的日期 getTime() 方法及示例

Java Date 类getTime()方法返回自 1970 年 1 月 1 日 00:00:00 GTM 以来的毫秒数,由 Date 对象表示。

句法:

返回值:它返回自 1970 年 1 月 1 日 00:00:00 GTM 以来的毫秒数。

异常:该函数不抛出任何异常。

下面的程序演示了上述函数:

// Java code to demonstrate
// getTime() function of Date class
  
import java.util.Date;
import java.util.Calendar;
public class GfG {
    // main method
    public static void main(String[] args)
    {
  
        // creating a Calendar object
        Calendar c1 = Calendar.getInstance();
  
        // set Month
        // MONTH starts with 0 i.e. ( 0 - Jan)
        c1.set(Calendar.MONTH, 11);
  
        // set Date
        c1.set(Calendar.DATE, 05);
  
        // set Year
        c1.set(Calendar.YEAR, 1996);
  
        // creating a date object with specified time.
        Date dateOne = c1.getTime();
  
        System.out.println("Date: " + dateOne);
  
        System.out.println(dateOne.getTime());
    }
}
输出:
