If i have some code such as input = new BufferedReader(new FileReader(args[0])); And the input file contain pairs of lines, how can I make it so only the first line from each line is imported? So in other words, every odd numbered line only?
Thanks
You might like to consider the use of
java.io.LineNumberReaderto make the filtering of odd lines (lineNo % 2 == 1) simpler. Or in an alternative approach, if you are using JDK7, you could use thejava.nio.files.Files.readAllLines()method and again filter the odd ones upon iteration.
