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);
} }
验证结果
