Java 中的 Calendar getTimeInMillis()方法示例
原文:https://www . geeksforgeeks . org/calendar-gettimeinmillis-method-in-Java-with-examples/
Calendar 类中的 getTimeInMillis() 方法用于以毫秒为单位返回此 Calendar 的当前时间。 语法:
public long getTimeInMillis()
参数:该方法不取任何参数。 返回值:该方法以毫秒为单位返回本日历的当前时间。 以下程序说明了日历类 getTimeInMillis()方法的工作: 例 1:
Java 语言(一种计算机语言，尤用于创建网站)
// Java code to illustrate
// getTimeInMillis() method
import java.util.*;
public class Calendar_Demo {
public static void main(String args[])
throws InterruptedException
{
// Creating a calendar
Calendar calndr1 = Calendar.getInstance();
// Displaying the current time
System.out.println("The Current Time"
+ " is: "
+ calndr1.getTimeInMillis());
// Adding few delay
Thread.sleep(10000);
// Creating another calendar
Calendar calndr2 = Calendar.getInstance();
// Displaying the upcoming time
System.out.println("The Upcoming Time"
+ " is: "
+ calndr2.getTimeInMillis());
}
}
Output:
The Current Time is: 1550725664034
The Upcoming Time is: 1550725674053
例 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java code to illustrate
// getTimeInMillis() method
import java.util.*;
public class Calendar_Demo {
public static void main(String args[])
throws InterruptedException
{
// Creating a calendar
Calendar calndr1 = Calendar.getInstance();
// Displaying the current time
System.out.println("The Current Time"
+ " is: "
+ calndr1.getTimeInMillis());
// Adding few delay
Thread.sleep(5000);
// Creating another calendar
Calendar calndr2 = Calendar.getInstance();
// Displaying the upcoming time
System.out.println("The Upcoming Time"
+ " is: "
+ calndr2.getTimeInMillis());
}
}
Output:
The Current Time is: 1550725683182
The Upcoming Time is: 1550725688208
