Answer 1

You can use removeAll(Collection<?> c) :

Removes all of this collection's elements that are also contained in the specified collection

al.removeAll(Arrays.asList(null,""));

This will remove all elements that are null or equals to "" in your List.

Output :

[name, asd]

Answer 2

You can remove an object by value.

while(al.remove(""));
