I have a the String Red*Blue*Yellow*Green*White. How do I break that String out by * into a List<String>?

Answer 1

You can try this: -

String str = "Red*Blue*Yellow*Green";
String[] arr = str.split("\\*");
List<String> list = new ArrayList<String>(Arrays.asList(arr));

NOTE:-

Arrays.asList returns you an unmodifiable list, so if you want a modifiable list, you need to create a new list by using the constructor of ArrayList, that takes a Collection object as parameter.

Also, since * is a special character in Regex, and String.split() takes a Regex for splitting. So, you need to escape the * with a backslash.

OUTPUT: -

[Red, Blue, Yellow, Green]

Answer 2

  String[] str ="Red*Blue*Yellow*Green*White".split("\\*");
    List<String> list = Arrays.asList(str);

Output:

[Red, Blue, Yellow, Green, White]

Answer 3

Please try this

       String ss="Red*Blue*Yellow*Green*Whit";
       String sss[] = ss.split("\\*");
       List <String> ssss = Arrays.asList(sss);
