下面是相同的演示 -
假设我们的输入是 -
run the program
期望的输出是 -
the current date and time is: 2022/03/17 23:43:17
算法step 1 - startstep 2 - declare an object of localdatetime namely date.step 3 - define the values.step 4 - define a date time format using datetimeformatter objectsstep 5 - display the date and time using a specific formatsstep 6 - stop
示例 1这里，我们将所有操作绑定到“main”函数下。
import java.time.format.datetimeformatter;import java.time.localdatetime;public class demo { public static void main(string[] args) { system.out.println("the required packages have been imported"); system.out.println("a localdatetime object has been defined"); datetimeformatter date_time = datetimeformatter.ofpattern("yyyy/mm/dd hh:mm:ss"); localdatetime now = localdatetime.now(); system.out.println("\nthe current date and time is: " +date_time.format(now)); }}
输出the required packages have been importeda localdatetime object has been definedthe current date and time is: 2022/03/17 23:43:17
示例 2在这里，我们将操作封装到展示面向对象编程的函数中。
import java.time.format.datetimeformatter;import java.time.localdatetime;public class demo { static void date_time(datetimeformatter date_time){ localdatetime now = localdatetime.now(); system.out.println("\nthe current date and time is: " +date_time.format(now)); } public static void main(string[] args) { system.out.println("the required packages have been imported"); system.out.println("a localdatetime object has been defined"); datetimeformatter date_time = datetimeformatter.ofpattern("yyyy/mm/dd hh:mm:ss"); date_time(date_time); }}
输出the required packages have been importeda localdatetime object has been definedthe current date and time is: 2022/03/29 08:55:28
以上就是java程序显示当前日期和时间的详细内容。
