arrays - In Java, remove empty elements from a list of Strings

Question

In Java, I have an ArrayList of Strings like:

[,Hi, ,How,are,you]

I want to remove the null and empty elements, how to change it so it is like this:

[Hi,How,are,you]

Answer 1

List<String> list = new ArrayList<String>(Arrays.asList("", "Hi", null, "How"));
System.out.println(list);
list.removeAll(Arrays.asList("", null));
System.out.println(list);

Output:

[, Hi, null, How]
[Hi, How]
