如何将Java LocalDateTime格式化为ISO_DATE_TIME格式
首先，设置日期：
LocalDateTime dateTime = LocalDateTime.of(2019, Month.JULY, 9, 10, 20);
现在，将日期时间格式化为ISO_DATE_TIME格式：
String str = dateTime.format(DateTimeFormatter.ISO_DATE_TIME);
示例
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.JULY, 9, 10, 20);
System.out.println("DateTime = "+dateTime);
String str = dateTime.format(DateTimeFormatter.ISO_DATE_TIME);
System.out.println("Formatted date = "+str);
}
}输出结果
DateTime = 2019-07-09T10:20 Formatted date = 2019-07-09T10:20:00
