问题描述

我的日期为"08/08/2019"，我希望它看起来像这样:"08，Aug 2019"，我尝试使用when，但想知道是否有更简单的方法吗?我知道这是一个很小的问题，但是我试图在互联网上找到答案，但找不到.

I have this date "08/08/2019" and I want it to look like this: "08, Aug 2019", I tried to use when but wondered if there is an easier way to do this? I know it's a bit small question but I tried to find an answer over the internet and I couldn't find this.

推荐答案

首先，您需要将字符串转换为Date对象，然后使用新的

first, you need to convert the string to Date object then convert it to your format using the new java.time

更新

val firstDate = "08/08/2019"
val formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy")
val date = formatter.parse(firstDate)
val desiredFormat = DateTimeFormatter.ofPattern("dd, MMM yyyy").format(date)
println(desiredFormat) //08, Aug 2019

旧答案

val firstDate = "08/08/2019"
val formatter = SimpleDateFormat("dd/MM/yyyy")
val date = formatter.parse(firstDate)
val desiredFormat = SimpleDateFormat("dd, MMM yyyy").format(date)
println(desiredFormat) //08, Aug 2019
