Given the following List:
List<String> list = new ArrayList<String>();
list.add("s1");
list.add("s2");
list.add(null);
list.add("s3");
list.add(null);
list.add("s4");
I need a helper class that removes null references. Something like:
SomeHelper.removeNullReference(list);
such that the list only contains “s1”, “s2”, “s4”, “s4” (non-null references).
What should I use to fulfill this requirement?
