while-loops

I use opencsv to parse csv files, and my code is

while( (line = reader.readNext()) != null ) { .... }

I got a compiler warning saying:

 comparing values of types Unit and Null using `!=' will always yield true
 [warn]     while( (aLine = reader.readNext()) != null ) {

How should I do the while loop?

As far as I understand, when you write a for-loop similar to this one for (int i = 0; i < SOME_NUM; i++) { if (true) do_something(); else do_something_else(); } The time complexity of this operation is mostly affected by the if (true) statement because the for-loop iterations don't… >>> More
