Converting a List<Long> to comma separated string

Hi I am having a requirement where I need to convert List of Long datatype 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 StringUtils join to get a String.

I am looking for java 7 solution,Not using guava or java 8.

You can try this:

StringUtils.join(mylist, ',');

See org.apache.commons.lang3.StringUtils.
