Converting a List<Long> to comma separated string
提问by user2375298
Hi I am having a requirement where I need to convert Listof Longdatatype to comma separated String.
Which would be the appropriate way. I have thought about using string builder or converting it to List<String>and then using StringUtilsjoin to get a String.
