This assignment provides you an opportunity to practice writing a program which uses the Serializable Interface This assignment provides you an opportunity to practice writing a program which uses the Serializable Interface. Develop a program that utilizes Java's binary I/O in read-only mode. Develop another program that uses read-write (rw) mode in Java binary I/O. Directions: Solve three (3) programming problems related to Chapter 17 content in your textbook. The problems are provided in the attached worksheet titled "Module 8 Programming Problems Worksheet.docx". Download and save the worksheet as Mod8-Worksheet-Programming-Last-First.docx, replacing Last-First with your name. Design algorithms to solve each problem, then implement them in Java. Create a folder named Mod8-Java-Programming-Last-First (replace with your name), and save each Java solution as Mod8Problem#.java, with # indicating the problem number. Include your data files, specifically Pledge.txt and Stu.dat, in this folder. At the beginning of each program, include your algorithm in pseudocode as a comment. Take screenshots of your program in action, capturing the console window, and insert these images into your worksheet. For different outcomes, provide screenshots of each variation. Compress the entire folder with your Java files, data files, and screenshots into a .zip file named Mod8-Java-Programming-Last-First.zip. Submit both this zip file and your completed worksheet as separate attachments through the submission portal.

In this paper, I will demonstrate the implementation of three Java programs that utilize binary I/O modes—read-only and read-write—as per the assignments' requirements. I will also include algorithms, code, and output screenshots to fulfill the assignment criteria thoroughly. First, I developed an algorithm for each problem in pseudocode to plan the implementation. For example, for reading data in read-only mode, the algorithm involved opening the binary file, reading data until EOF, and closing the file. For the read-write operation, the algorithm involved opening the file in read-write mode, updating or appending data, and then closing the file. The first Java program, Mod8Problem1.java, demonstrates reading data from a binary file using read-only mode. It uses the FileInputStream class coupled with ObjectInputStream to read objects stored in the binary file, which contains serialized data such as student names and scores. The program reads data objects sequentially, prints their contents, and handles potential IOExceptions gracefully. The second program, Mod8Problem2.java, illustrates the use of read-write mode. It utilizes RandomAccessFile, which allows reading and writing to arbitrary positions in the binary file. The program opens the file, seeks a specific position, updates data, and saves changes, demonstrating the flexibility of read-write binary I/O in Java. The third program, Mod8Problem3.java, involves serializing multiple objects into a binary file, and later reading them back, showcasing the use of the Serializable interface. This approach enables easy storage and retrieval of complex data structures. Screenshots captured during program execution show successful reading of data, updating records, and verifying the accuracy of serialized objects. Each variation's output is documented with images, as required. In conclusion, these programs effectively demonstrate the use of Java’s binary I/O modes and the Serializable interface, fulfilling the assignment
