    When I am using this line I am getting a stange out put

    br = new BufferedReader(new FileReader("myfile2.txt"));
    while(br.readLine() != null)
    {
    System.out.println(br.readLine());
    }

    new file2
    new file4

    When my file data is :

    PrintWriter pwd = new PrintWriter(file);
    pwd.println("new file");
    pwd.println("new file2");
    pwd.println("new file3");
    pwd.println("new file4");

    Why it is reading alternate lines when I use above code?
