import static java.nio.file.StandardOpenOption.*;
public class CreateOneRandomAccessRecord
{
public static void main(String[] args)
{
Path file =
Paths.get("C: \\Java\\Chapter.13\\RandomEmployees.txt");
String s = "002,Newmann,12.25" +
System.getProperty("line.separator");
______________________________________
byte[] data = s.getBytes();
ByteBuffer buffer = ByteBuffer.wrap(data);
FileChannel fc = null;
try
{
fc = (FileChannel)Files.newByteChannel(file, READ, WRITE);
fc.position(2 * RECSIZE);
fc.write(buffer);
fc.close();
}
catch (Exception e)
{
System.out.println("Error message: " + e);
}
}
}
The above program creates a single employee record for employee number 002 with a last name of Newmann and a pay rate of 12.25. In the shaded line provided, create a statement that assigns the length of the string to RECSIZE.
