java8 LocalDateTime 格式化

LocalDateTime格式化

LocalDateTime time=LocalDateTime.now();

System.out.println(time);

DateTimeFormatter dtf2 = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

String strDate2 = dtf2.format(time);

System.out.println(strDate2);

 

 

LocalDate转String ，String转LocalDate

LocalDate data=LocalDate.now();

System.out.print(data);

DateTimeFormatter dtf3 = DateTimeFormatter.ofPattern("yyyy-MM-dd");

String strDate3 = dtf3.format(data);

System.out.println(strDate3);

strDate3=strDate3+" 04:00:00";

LocalDateTime time1=LocalDateTime.parse(strDate3,dtf2);

System.out.print(time1);

System.out.print(time.isAfter(time1));
