How to split String by comma in Java - Example Tutorial

In the earlier article, I have shown you how to split String by regular expression and now, you will learn how to split String by comma.

The split method will return an array of String, which you can further convert to a list of String. If your String contains a leading or trailing white space, make sure you trim the String before calling the split() method.
