Tal Angel :
Please look at my code
String Str = "E_1000, E_1005,E_1010 , E_1015,E_1020,E_1025";
List<String> splitStr = Arrays.asList(Str.split(","));
My list (splitStr) has strings with white spaces.
Is there a way to split the string and trim all the elements in one line of code?
Avi :
Yes, simply do:
String str = "E_1000, E_1005,E_1010 , E_1015,E_1020,E_1025";
List<String> splitStr = Arrays.stream(str.split(","))
.map(String::trim)
.collect(Collectors.toList());
Explanation:
First, we split on ,:
str.split(",")
Then, we turn it into a Stream of (untrimmed) Strings:
Arrays.stream(str.split(","))
Next, we trim all the Strings in the Stream:
Arrays.stream(str.split(","))
.map(String::trim)
Finally, we collect all the trimmed Strings into a List:
Arrays.stream(str.split(","))
.map(String::trim)
.collect(Collectors.toList());
