Write a program that reads a text file and writes its every odd line in another file.
Line numbers starts from 0.
Read 01_OddLinesIn.txt and test your output against 01_OddLinesOut.txt, then read 02_OddLinesIn.txt and test against its respective output file and so on.

Here is the solution:
import java.io.*;
public class Pr_01_OddLines {
public static void main(String[] args) throws IOException {
File fileIn1 = new File("resources\\01_OddLinesIn.txt");
try (BufferedReader bf = new BufferedReader(new FileReader(fileIn1))) {//SURROUND WITH try with resources FOR THE EXCEPTIONS
String readLine;
int line = 0;
while ((readLine = bf.readLine()) != null) {
if (line % 2 != 0) {//CHECKING WHETHER THE ROW IS ODD
System.out.println(readLine);
}
line++;
}
}
}
}
