Exam 13: File Input and Output

import java.nio.file.*; public class PathDemo {     public static void main(String[] args)     {         Path filePath = Paths.get("C:\\Java\\Input.Output\\LessonInfo.txt");         int count = filePath.getNameCount();         System.out.println("Path is " + filePath.toString());         System.out.println("File name is " +           filePath.getFileName());         System.out.println("There are " + count +           " elements in the file path");         for(int x = 0; x < count; ++x)             System.out.println("Element " + x + " is " +             filePath.getName(x));     } } The above code demonstrates the creation of a Path and its method. Describe the output that will display when the code is executed.

Provide an example of batch processing.

InputStream is a child of FileInputStream .

FileChannel fc = null; Path file = Paths.get("C:\\Java\\Chapter.13\\RandomEmployees.txt"); Given the two declarations above, write a Java statement that creates a ByteChannel that is cast to a FileChannel . The file shoould be open for read and write operations.
