Read text file in java

Question

Hey, I need to read a textfile in java. The problem is that the file has the following format:

Id time1 time2 time3 ...
ID2 time1 time2 time3 ...
         


        

Answer 1

Transpose the file. Ids on line 1, time1 on line 2, and so on. Of course, this is beneficial if this can be done only once and then many reads on that file are expected.
