Help with Java Programming Assignment Please?

I have a java assignment due for college (I'm doing 2nd year multimedia programming) in a few weeks and I’m really struggling and don’t have a clue what to do.

The following is the first part of the assignment. I have to implement a Java application that demonstrates the use of file input/output and exception handling. my application should allow the user to enter data about some entity that is stored in a data file. My application should be able to read data from a data file, and to store that data in a set of objects.

The following is what I have already. A lot of it is probably wrong, and I don't know what to do next.

BookTest.java

Code java:

package books;
 
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.PrintWriter;
import java.util.Scanner;
 
public class BookTest {
 
    public static void main(String[] args) 
            throws FileNotFoundException
    {  
 
        File f = new File (input.txt);
 
        if ();
        {
            FileReader = new FileReader();
        }
 
       /* BufferedReader = new BufferedReader();
        PrintWriter pw = new PrintWriter(File);*/
 
        //Prompts the user for the input and output file names
       /* Scanner console = new Scanner(System.in);
        System.out.print("Input file: ");
        String inputFileName = console.next();
        System.out.print("Output file: ");
        String outputFileName = console.next();
 
        //Prompts the Scanner and PrintWriter objects for reading and writing
        File inputFile = new File(inputFileName);
        Scanner in = new Scanner(inputFile);      
        PrintWriter out = new PrintWriter(outputFileName);
        int lineNumber = 1;
        */
 
 
 
        /*  while (in.hasNextLine());
        {
            String line = in.nextLine();
            out.println("/* " + lineNumber + " * " + line);
        }
        in.close();
        out.close();   */
 
    }
}

Books.java

Code java:

package books;
 
public class Books {
 
    private String title;
    private String authorFName;
    private String authorLName;
    private double price;    
}

I would really appreciate it if anyone could help me please. Thank you.
