How to convert a String of format yyyymmdd to LocalDate in JodaTime
提问by user1548157
I have a String in the form "20140518". How to convert it into LocalDate object
我有一个“20140518”形式的字符串。如何将其转换为 LocalDate 对象
I tried this
我试过这个
this.todayDate = new LocalDate(val);
System.out.println(todayDate.toString("yyyy-mm-dd"))
When I try dumping this to standard output it dumps like 20140518-junk-junk. That it dumps a garbage string . I thought it would dump like 2014-05-18.
当我尝试将其转储到标准输出时,它会转储像 20140518-junk-junk。它转储垃圾字符串。我认为它会像 2014-05-18 一样倾倒。

Use MMthat represents Month instead of mmthat represents minutes.
使用MM代表月份而不是mm代表分钟。
Use LocalDate.parse()instead of new LocalDate()to construct the LocalDateobject.
使用LocalDate.parse()代替new LocalDate()来构造LocalDate对象。
DateTimeFormatter format = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd");
LocalDate lDate = org.joda.time.LocalDate.parse("20140518", format);
System.out.println(lDate);
output:
输出:
2014-05-18
org.joda.time.LocalDate#toString()be default uses yyyy-MM-ddpattern.
org.joda.time.LocalDate#toString()默认使用yyyy-MM-dd模式。
You don't need to use todayDate.toString("yyyy-MM-dd").
您不需要使用todayDate.toString("yyyy-MM-dd").
