Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    LineNumberReader r = new LineNumberReader(new FileReader("yourFile.txt"));

    String line = null;//from  w  ww  . j av  a  2 s .  com

    while ((line = r.readLine()) != null) {
        System.out.println(r.getLineNumber() + ": " + line);
    }
    r.close();
}

From source file:MainClass.java

public static void main(String[] args) throws Exception {

    String nextLine = null;/*w ww  .j  a  va 2 s .co m*/
    System.out.println("Type any text and press return. Type 'exit' to quit the program.");
    try {
        while ((nextLine = lineCounter.readLine()).indexOf("exit") == -1) {
            if (nextLine == null)
