从字符串中删除前导空格

Question

I have a String like follows

 abc, def tgy, awed djdj

Now i want to get all the parts of this string seperated by comma. Best way i can image is doing the following

final String[] splits = country.split(",");

Now i should have a array with 3 strings. But i dont want the leading spaces in each string also. How can i remove them. Is there a special way to do that? Or i have to use the same old regex way to remove the leading spaces.

Answer 1

您可以使用此正则表达式从拆分元素中删除前导/后缀空格：

final String[] splits = country.trim().split(" *, *");

Answer 2

在字符串上使用此调用可删除前导和尾随空格：

arbitraryVariable = arbitraryVariable.trim()

Answer 3

,\s*

You can split by this as well.This will remove leading spaces.See demo.
