The Readline () method of the bufferedreader object must handle java. Io. ioexception (exception ).

One row can be read at a time:

Import java. Io. filereader;
Import java. Io. filewriter;
Import java. Io. bufferedreader;
Import java. Io. bufferedwriter;
Import java. Io. ioexception;
Public class consoleoutput {
Public static void main (string Arg []) {
If (Arg. length! = 2 ){
System. Out. println ("Usage: Java copytextlines <infile> <OUTFILE> ");
Return;
}
Try {
String STR;
Filereader Fr = new filereader (ARG [0]);
Bufferedreader BR = new bufferedreader (FR );
Filewriter fw = new filewriter (ARG [1]);
Bufferedwriter BW = new bufferedwriter (FW );
While (STR = Br. Readline ())! = NULL)
Bw. Write (STR );
BR. Close ();
Bw. Close ();
} Catch (ioexception e ){
System. Out. println (E );
}
}
}
