原文:https://www . geesforgeks . org/date-gettime-method-in-Java-with-examples/
Java Date 类的 getTime() 方法返回自 1970 年 1 月 1 日 00:00:00 GTM 以来的毫秒数，用 Date 对象表示。
语法:
public long getTime()
参数:函数不接受任何参数。
返回值:返回 1970 年 1 月 1 日 00:00:00 GTM 以来的毫秒数。
异常:函数不抛出任何异常。
下面的程序演示了上述功能:
// 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());
}
}
Output:
Date: Thu Dec 05 09:29:39 UTC 1996

Date dateOne = c1.getTime();
System.out.println("Date: " + dateOne);
System.out.println(dateOne.getTime());
}
}
Output:
