Answer:
No. It cannot be the final destination of data, so it should be connected to some other stream.

import java.io.*;
class WriteTextFile3
{
public static void main ( String[] args )
{
String fileName = "reaper.txt" ;
PrintWriter print = null;
try
{
print = new PrintWriter( new BufferedWriter( new FileWriter( fileName ) ) );
}
catch ( IOException iox )
{
System.out.println("Problem writing " + fileName );
}
print.println( "No Nightingale did ever chaunt" );
print.println( "More welcome notes to weary bands" );
print.println( "Of travellers in some shady haunt," );
print.println( "Among Arabian sands." );
print.close();
}
}
The updated example program uses a BufferedWriter
and a PrintWriter.
The println() prints one line of text and ends each line
with the
correct codes
for whatever operating system you are running.
Creating the file might throw an exception, so a try/catch structure
is needed for the constructor.
However the println() statements do not throw exceptions and
can be moved outside of the
structure.
Is close() necessary in this program?
