首先,设置日期:
LocalDateTime dateTime = LocalDateTime.of(2019, Month.SEPTEMBER, 9, 10, 20);
现在,将日期时间格式化为ISO_WEEK_DATE格式:
String str = dateTime.format(DateTimeFormatter.ISO_WEEK_DATE);
import java.time.LocalDateTime;
import java.time.Month;
import java.time.format.DateTimeFormatter;
public class Demo {
public static void main(String[] args) {
LocalDateTime dateTime = LocalDateTime.of(2019, Month.SEPTEMBER, 9, 10, 20);
System.out.println("DateTime = "+dateTime);
String str = dateTime.format(DateTimeFormatter.ISO_WEEK_DATE);
System.out.println("Formatted date = "+str);
}
}输出结果
DateTime = 2019-09-09T10:20 Formatted date = 2019-W37-1
