How to convert a String into an ArrayList?

Question

In my String, I can have an arbitrary number of words which are comma separated. I wanted each word added into an ArrayList. E.g.:

String s = "a,b,c,d,e,.........";

Answer 1

Try something like

List<String> myList = new ArrayList<String>(Arrays.asList(s.split(",")));

• Arrays.asList documentation
• String.split documentation
• ArrayList(Collection) constructor documentation

Demo:

String s = "lorem,ipsum,dolor,sit,amet";

List<String> myList = new ArrayList<String>(Arrays.asList(s.split(",")));

System.out.println(myList);  // prints [lorem, ipsum, dolor, sit, amet]
