Answer 1

Save this code as public in Code Playground, then edit your question and change the wall of code for a link to the code in Code Playground. This is better to test and debug.
Then, use question description to explain the problem. Which class, which list, which line, which error?
Also, change the tag to the language name. This is important for future searches.
