Getters and setters

Getters and setters — are methods that provide controlled access to private fields. 

public class Car {
    private String color;
    private int speed;

    // Getter for color
    public String getColor() {
        return color;
    }

    // Setter for color
    public void setColor(String color) {
        this.color = color;
    }
}

This is essential for encapsulation, allowing you to protect and control changes to data.
