Download Visual Basic course and exercises

Hello

Here is the free course in French for Visual Basic

```java import java.io.*; import java.util.ArrayList; class Person implements Serializable { private String name; private int age; public Person(String name, int age) { this.name = name; this.age = age; } public String getName() { return name; } public int getAge() { return age; } @Override public String toString() { return "Person{name='" + name + "', age=" + age + "}"; } } public class SerializationExample { public static void main(String[] args) { ArrayList people = new ArrayList<>(); people.add(new Person("Alice", 30)); people.add(new Person("Bob", 25)); // Serialization try (ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("people.ser"))) { oos.writeObject(people); } catch (IOException e) { e.printStackTrace(); } // Deserialization ArrayList deserializedPeople = null; try (ObjectInputStream ois = new ObjectInputStream(new FileInputStream("people.ser"))) { deserializedPeople = (ArrayList) ois.readObject(); } catch (IOException | ClassNotFoundException e) { e.printStackTrace(); } // Displaying the deserialized list if (deserializedPeople != null) { for (Person person : deserializedPeople) { System.out.println(person); } } } } ```

Hello,

Is a "Hello", "Please", and a properly phrased question too much to ask?
