I like using Guava for this purpose. Neat and very useful:

Joiner.on(",").join(myList)

This kind of code has been written time and time again and you should rather be freed implementing your specific implementation logic.

If you use maven, herewith the dependency:

    com.google.guava
    guava
    28.1-jre

It has a bunch of other wonderful cool features too!

This will produce the string "one, two, and three".

List originalList = Arrays.asList("one", "two", "three");
Joiner.on(", ")
    .join(originalList.subList(0, originalList.size() - 1))
    .concat(", and ")
    .concat(originalList.get(originalList.size() - 1));
