How to add or insert ' (single quotes) for every string in a list in which strings are separated by commas using Java

Question

I have a list as below

[url1,url2,url3,url4]  

This list will be based on multiple selection from drop down list of HTML. So list size i.e., list elements change dynamically. My problem is I am unable to get the logic for getting single quotes to the strings. I want the above string list to be displayed as

'url1','url2','url3','url4'  

That is single quotes (') for each string and commas (,) should not be eliminated. Please help me how to achieve this using Java.

Answer 1

for list you can convert this by Java 8

 list.stream().collect(Collectors.joining("','", "'", "'"));
