LocalDate/本地时间和LocalDateTime类简化时区不需要开发。
让我们来看看他们操作。
选择使用任何编辑器创建以下java程序在 C:/> JAVA
Java8Tester.java
import java.time.LocalDate;import java.time.LocalTime;import java.time.LocalDateTime;import java.time.Month;public class Java8Tester { public static void main(String args[]){ Java8Tester java8tester = new Java8Tester(); java8tester.testLocalDateTime(); } public void testLocalDateTime(){ // Get the current date and time LocalDateTime currentTime = LocalDateTime.now(); System.out.println("Current DateTime: " + currentTime); LocalDate date1 = currentTime.toLocalDate(); System.out.println("date1: " + date1); Month month = currentTime.getMonth(); int day = currentTime.getDayOfMonth(); int seconds = currentTime.getSecond(); System.out.println("Month: " + month +"day: " + day +"seconds: " + seconds ); LocalDateTime date2 = currentTime.withDayOfMonth(10).withYear(2012); System.out.println("date2: " + date2); //12 december 2014 LocalDate date3 = LocalDate.of(2014, Month.DECEMBER, 12); System.out.println("date3: " + date3); //22 hour 15 minutes LocalTime date4 = LocalTime.of(22, 15); System.out.println("date4: " + date4); //parse a string LocalTime date5 = LocalTime.parse("20:15:30"); System.out.println("date5: " + date5); } }
