question 64

Short Answer

import java.nio.file.*;
import java.io.*;
import java.nio.channels.FileChannel;
import java.nio.ByteBuffer;
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");
       --------- Code here -------------
       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 indicated space, create a statement that assigns the length of the string to RECSIZE .
