The solution:
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
public class Pr_02_LineNumbers {
public static void main(String[] args) throws IOException {
String source = "resources\\02_OddLinesIn.txt";
try (BufferedReader bf = new BufferedReader(new FileReader(new File(source)))) {
String readLine;
int counter = 1;
while ((readLine = bf.readLine()) != null) {
System.out.printf("%d. %s%n", counter, readLine);
counter++;
}
}
}
}
