This code reads the file line by line. public static void readFileByLine(String fileName) { try { File file = new File(fileName); Scanner scanner = new Scanner(file); while (scanner.hasNext()) { System.out.println(scanner.next()); } scanner.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } } You can also set a delimiter as a line separator and then perform the same. … Read more

You have to remember the position by calling file.tell() before the readline and then calling file.seek() to rewind. Something like: fp = open(‘myfile’) last_pos = fp.tell() line = fp.readline() while line != ”: if line == ‘SPECIAL’: fp.seek(last_pos) other_function(fp) break last_pos = fp.tell() line = fp.readline() I can’t recall if it is safe to call … Read more
At your Bash prompt, press Ctrl–v Ctrl–Left-Arrow and Ctrl–v Ctrl–Right-Arrow and make note of the output. You should see something like: ^[OD and ^[OC or similar. Add the following lines to your ~/.inputrc: “\eOC”: forward-word “\eOD”: backward-word where you will substitute \e for escape (^[) and the rest of the characters you got (OD, OC … Read more
You should add “throws IOException” to your main method: public static void main(String[] args) throws IOException { You can read a bit more about checked exceptions (which are specific to Java) in JLS.
