Java Input/Output - School4Tech

Java I/O (Input/Output) operations refer to the process of reading data from input sources and writing data to output destinations. Java provides a comprehensive set of classes and methods in the java.io package to perform I/O operations.

Here’s an example of how Java I/O operations can be used to read and write information about cars:

import java.io.*;

class Car implements Serializable {
    private String make;
    private String model;
    private int year;
    private int speed;

    public Car(String make, String model, int year, int speed) {
        this.make = make;
        this.model = model;
        this.year = year;
        this.speed = speed;
    }

    public String getMake() {
        return make;
    }

    public String getModel() {
        return model;
    }

    public int getYear() {
        return year;
    }

    public int getSpeed() {
        return speed;
    }

    @Override
    public String toString() {
        return make + " " + model + " " + year + " " + speed;
    }
}

public class CarIOExample {
    public static void main(String[] args) {
        Car car = new Car("Toyota", "Camry", 2019, 120);

        // Write car information to a file
        try (FileOutputStream fos = new FileOutputStream("car.ser");
             ObjectOutputStream oos = new ObjectOutputStream(fos)) {
            oos.writeObject(car);
        } catch (IOException e) {
            e.printStackTrace();
        }

        // Read car information from a file
        try (FileInputStream fis = new FileInputStream("car.ser");
             ObjectInputStream ois = new ObjectInputStream(fis)) {
            Car readCar = (Car) ois.readObject();
            System.out.println("Read car: " + readCar);
        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}

import java.io.*;

class Car implements Serializable {

private String make;

private String model;

private int year;

private int speed;

public Car(String make, String model, int year, int speed) {

this.make = make;

this.model = model;

this.year = year;

this.speed = speed;

}

public String getMake() {

return make;

}

public String getModel() {

return model;

}

public int getYear() {

return year;

}

public int getSpeed() {

return speed;

}

@Override

public String toString() {

return make + " " + model + " " + year + " " + speed;

}

public class CarIOExample {

public static void main(String[] args) {

Car car = new Car("Toyota", "Camry", 2019, 120);

// Write car information to a file

try (FileOutputStream fos = new FileOutputStream("car.ser");

ObjectOutputStream oos = new ObjectOutputStream(fos)) {

oos.writeObject(car);

} catch (IOException e) {

e.printStackTrace();

}

// Read car information from a file

try (FileInputStream fis = new FileInputStream("car.ser");

ObjectInputStream ois = new ObjectInputStream(fis)) {

Car readCar = (Car) ois.readObject();

System.out.println("Read car: " + readCar);

} catch (IOException | ClassNotFoundException e) {

e.printStackTrace();

}

In this example, a Car class is defined, which implements the Serializable interface. This allows objects of the Car class to be written to and read from a file. The main method creates a Car object, writes it to a file using an ObjectOutputStream, and then reads it back using an ObjectInputStream. The read Car object is then printed to the console to demonstrate that the information was correctly written to and read from the file.Regenerate response
