2. Using java.util.Date First, we’ll try with the simple way to get the time in milliseconds format is from Date class. Date class has a method getTime()which returns the milliseconds in long value for the given time or current time. ...

// 将当前时间转换为毫秒数longtimeInMilliseconds=currentTimeMillis; 1. 2. 3. 将毫秒数转换为int类型 最后,我们需要将毫秒数转换为int类型。在Java中,可以使用类型转换操作符(int)将long类型转换为int类型。 // 将毫秒数转换为int类型inttimeInSeconds=(int)(timeInMilliseconds/1000); ...
import java.util.Calendar; Now, use the getTimeInMillis() method to get the time in milliseconds. cal.getTimeInMillis() The following is the final example. Example Live Demo importjava.util.Calendar;publicclassDemo{publicstaticvoidmain(String[]args){Calendarcal=Calendar.getInstance();System.out...

在Java中，gettimeinmillis主要通过System.currentTimeMillis()方法来实现。该方法返回自1970年1月1日UTC时间以来的毫秒数。下面通过一个简单的示例来演示其使用方法：public class GetTimeMillisExample { public static void main(String[] args) { long currentTimeMillis = System.currentTimeMillis();System.out....
