public class Testwriter
{
Function: Reads the contents of the E:/test.txt file (read one line) and writes its contents to the E:/jack.txt
Knowledge Point: Java reads the file, writes the file---< by the character Stream way >
public static void Main (string[] args)
{
Try
{
Create a FileReader object to read a character stream
FileReader FR = new FileReader ("E:/test.txt");
Buffer the input of the specified file
BufferedReader br = new BufferedReader (FR);
Creates a FileWriter object that is used to write character streams
FileWriter FW = new FileWriter ("E:/jack.txt");
Will buffer the output to the file
BufferedWriter bw = new BufferedWriter (FW);
Defines a variable of type string that is used to read one row at a time
String Myreadline;
while (Br.ready ())
{
Read one line
Myreadline = Br.readline ();
Write to File
Bw.write (Myreadline);
Bw.newline ();
Output on the screen
System.out.println (Myreadline);
}
Refresh the buffer for this stream
Bw.flush ();
Bw.close ();
Br.close ();
Fw.close ();
Br.close ();
Fr.close ();
