Example:

public class Brandbworpwdemo {public    static void Main (string[] args) throws ioexception{         //Read and write         to file BufferedReader br = new BufferedReader (new                InputStreamReader (                        new FileInputStream ("E:\\javaio\\imooc.txt")) );        /*bufferedwriter bw = new BufferedWriter (new                outputstreamwriter (                        new FileOutputStream ("e:\\javaio\\ Imooc3.txt "))); * *
        PrintWriter pw = new PrintWriter ("E:\\javaio\\imooc4.txt");//        //printwriter PW1 = new PrintWriter (OutputStream, Boolean autoflush);        String Line;        while (lines = Br.readline ())!=null) {            System.out.println (line);//read one row at a time, and do not recognize the newline            /*bw.write (line);            Write the line-break operation separately            bw.newline ();//newline Operation            Bw.flush (); */            Pw.println (line)            ; Pw.flush ();        }        Br.close ();        Bw.close ();        Pw.close ();    }}
