You create a new FileOutputStream
object by
passing the name of the file to the constructor, like this:
FileOutputStream fos = new
FileOutputStream("16.html");
If a file with this name already exists in the current working directory, it will be overwritten by the new data. If the file doesn't exist it will be created in the current directory.
The following example reads user input from System.in
and writes it into the files specified on the
command line.
import java.io.*;
public class MultiType {
public final static int BUFFER_SIZE = 4096;
public static void main(String[] args) {
FileOutputStream[] fos = new FileOutputStream[args.length];
for (int i = 0; i < args.length; i++) {
try {
fos[i] = new FileOutputStream(args[i]);
}
catch (IOException ex) {
System.err.println(e);
}
} // end for
try {
byte[] buffer = new byte[BUFFER_SIZE];
while (true) {
int result = System.in.read(buffer);
if (result == -1) break;
for (int i = 0; i < args.length; i++) {
try {
fos[i].write(buffer, 0, result);
}
catch (IOException ex) {
System.err.println(ex.getMessage());
}
} // end for
} // end while
} // end try
catch (IOException ex) {
System.err.println(e);
}
} // end main
}
