Have you ever implemented Generic classes yourself?

Yes, I have implemented Generic classes in Java to create universal and reusable components. Generics allow parameterizing types, which enhances type safety and reduces the need for casting.

An example of a simple Generic class is a container for storing a single object of any type:

public class Box<T> {
    private T value;

    public Box(T value) {
        this.value = value;
    }

    public T getValue() {
        return value;
    }

    public void setValue(T value) {
        this.value = value;
    }
}

// Usage:
Box<String> stringBox = new Box<>("Hello");
String s = stringBox.getValue();

Box<Integer> intBox = new Box<>(123);
Integer i = intBox.getValue();

This approach allows creating classes that work with different types without losing type safety.
