How can we write objects of 10 students into a data file in Java Programming Language?

Answer 1

To write objects of 10 students into a data file in Java, you can use ObjectOutputStream in combination with FileOutputStream. First, create a Student class that implements Serializable. Then, open a FileOutputStream to the desired file, wrap it with ObjectOutputStream, and use a loop to write each student object to the file. Finally, close the output stream to ensure all data is flushed and resources are released. Here's a simple example:

FileOutputStream fileOut = new FileOutputStream("students.dat");
ObjectOutputStream out = new ObjectOutputStream(fileOut);
for (int i = 0; i < 10; i++) {
    out.writeObject(new Student(/* parameters */));
}
out.close();
