I would like to write a linked list like this:
"a" -> "b" -> "c" -> "d"
This is what I've tried so far but it's obviously wrong. I was wondering how to express this correctly in java?
LinkedList<String> s = new LinkedList<>();
s = {"a"->"b"->"c"->"d"};
Thanks!
That's how the pointers in the list look internally, to actually add it to the list you need to do this:
List<String> s = new LinkedList<>();
s.add("a");
s.add("b");
s.add("c");
s.add("d");
Take a look at this answer.
LinkedList<String> list = new LinkedList<>();
list.add("a");
list.add("b");
list.add("c");
list.add("d");
If you really want it on one line:
LinkedList<String> list = new LinkedList<>(Arrays.asList("a","b","c","d"));
Though that does have a performance overhead.
You could do this:
LinkedList<String> linkedList = new LinkedList<String>();
linkedList.add("a");
linkedList.add("b");
linkedList.add("c");
linkedList.add("d");
